Constant Value: "audio"

BATTERY_SERVICE

String BATTERY_SERVICE

Use with getSystemService(Class ) to retrieve a BatteryManager for managing battery state.

Constant Value: "batterymanager"

BIND_ABOVE_CLIENT

int BIND_ABOVE_CLIENT

Flag for bindService(Intent, ServiceConnection, int): indicates that the client application binding to this service considers the service to be more important than the app itself. When set, the platform will try to have the out of memory killer kill the app before it kills the service it is bound to, though this is not guaranteed to be the case.

Constant Value: 8 (0x00000008)

BIND_ADJUST_WITH_ACTIVITY

int BIND_ADJUST_WITH_ACTIVITY

Flag for bindService(Intent, ServiceConnection, int): If binding from an activity, allow the target service's process importance to be raised based on whether the activity is visible to the user, regardless whether another flag is used to reduce the amount that the client process's overall importance is used to impact it.

Constant Value: 128 (0x00000080)

BIND_ALLOW_OOM_MANAGEMENT

int BIND_ALLOW_OOM_MANAGEMENT

Flag for bindService(Intent, ServiceConnection, int): allow the process hosting the bound service to go through its normal memory management. It will be treated more like a running service, allowing the system to (temporarily) expunge the process if low on memory or for some other whim it may have, and being more aggressive about making it a candidate to be killed (and restarted) if running for a long time.

Constant Value: 16 (0x00000010)

BIND_AUTO_CREATE

int BIND_AUTO_CREATE

Flag for bindService(Intent, ServiceConnection, int): automatically create the service as long as the binding exists. Note that while this will create the service, its onStartCommand(Intent, int, int) method will still only be called due to an explicit call to startService(Intent). Even without that, though, this still provides you with access to the service object while the service is created.

Note that prior to ICE_CREAM_SANDWICH, not supplying this flag would also impact how important the system consider's the target service's process to be. When set, the only way for it to be raised was by binding from a service in which case it will only be important when that activity is in the foreground. Now to achieve this behavior you must explicitly supply the new flag BIND_ADJUST_WITH_ACTIVITY. For compatibility, old applications that don't specify BIND_AUTO_CREATE will automatically have the flags BIND_WAIVE_PRIORITY and BIND_ADJUST_WITH_ACTIVITY set for them in order to achieve the same result.

Constant Value: 1 (0x00000001)

BIND_DEBUG_UNBIND

int BIND_DEBUG_UNBIND

Flag for bindService(Intent, ServiceConnection, int): include debugging help for mismatched calls to unbind. When this flag is set, the callstack of the following unbindService(ServiceConnection) call is retained, to be printed if a later incorrect unbind call is made. Note that doing this requires retaining information about the binding that was made for the lifetime of the app, resulting in a leak -- this should only be used for debugging.

Constant Value: 2 (0x00000002)

BIND_EXTERNAL_SERVICE

int BIND_EXTERNAL_SERVICE

Flag for bindService(Intent, ServiceConnection, int): The service being bound is an isolated, external service. This binds the service into the calling application's package, rather than the package in which the service is declared.

When using this flag, the code for the service being bound will execute under the calling application's package name and user ID. Because the service must be an isolated process, it will not have direct access to the application's data, though. The purpose of this flag is to allow applications to provide services that are attributed to the app using the service, rather than the application providing the service.

Constant Value: -2147483648 (0x80000000)

BIND_IMPORTANT

int BIND_IMPORTANT

Flag for bindService(Intent, ServiceConnection, int): this service is very important to the client, so should be brought to the foreground process level when the client is. Normally a process can only be raised to the visibility level by a client, even if that client is in the foreground.

Constant Value: 64 (0x00000040)

BIND_NOT_FOREGROUND

int BIND_NOT_FOREGROUND

Flag for bindService(Intent, ServiceConnection, int): don't allow this binding to raise the target service's process to the foreground scheduling priority. It will still be raised to at least the same memory priority as the client (so that its process will not be killable in any situation where the client is not killable), but for CPU scheduling purposes it may be left in the background. This only has an impact in the situation where the binding client is a foreground process and the target service is in a background process.

Constant Value: 4 (0x00000004)

BIND_WAIVE_PRIORITY

int BIND_WAIVE_PRIORITY

Flag for bindService(Intent, ServiceConnection, int): don't impact the scheduling or memory management priority of the target service's hosting process. Allows the service's process to be managed on the background LRU list just like a regular application process in the background.

Constant Value: 32 (0x00000020)

BLUETOOTH_SERVICE

String BLUETOOTH_SERVICE

Use with getSystemService(Class ) to retrieve a BluetoothManager for using Bluetooth.

Constant Value: "bluetooth"

Constant Value: "carrier_config"

CLIPBOARD_SERVICE

String CLIPBOARD_SERVICE

Use with getSystemService(Class ) to retrieve a ClipboardManager for accessing and modifying ClipboardManager for accessing and modifying the contents of the global clipboard.

Constant Value: "clipboard"

Constant Value: "connectivity"

CONSUMER_IR_SERVICE

String CONSUMER_IR_SERVICE

Use with getSystemService(Class ) to retrieve a ConsumerIrManager for transmitting infrared signals from the device.

Constant Value: "consumer_ir"

CONTEXT_IGNORE_SECURITY

int CONTEXT_IGNORE_SECURITY

Flag for use with createPackageContext(String, int): ignore any security restrictions on the Context being requested, allowing it to always be loaded. For use with CONTEXT_INCLUDE_CODE to allow code to be loaded into a process even when it isn't safe to do so. Use with extreme care!

Constant Value: 2 (0x00000002)

CONTEXT_INCLUDE_CODE

int CONTEXT_INCLUDE_CODE

Flag for use with createPackageContext(String, int): include the application code with the context. This means loading code into the caller's process, so that getClassLoader() can be used to instantiate the application's classes. Setting this flags imposes security restrictions on what application context you can access; if the requested application can not be safely loaded into your process, java.lang.SecurityException will be thrown. If this flag is not set, there will be no restrictions on the packages that can be loaded, but getClassLoader() will always return the default system class loader.

Constant Value: 1 (0x00000001)

CONTEXT_RESTRICTED

int CONTEXT_RESTRICTED

Flag for use with createPackageContext(String, int): a restricted context may disable specific features. For instance, a View associated with a restricted context would ignore particular XML attributes.

Constant Value: 4 (0x00000004)

MODE_APPEND

int MODE_APPEND

File creation mode: for use with openFileOutput(String, int), if the file already exists then write data to the end of the existing file instead of erasing it.

Constant Value: 32768 (0x00008000)

MODE_ENABLE_WRITE_AHEAD_LOGGING

int MODE_ENABLE_WRITE_AHEAD_LOGGING

Database open flag: when set, the database is opened with write-ahead logging enabled by default.

Constant Value: 8 (0x00000008)

MODE_MULTI_PROCESS

int MODE_MULTI_PROCESS

This constant was deprecated in API level 23.
MODE_MULTI_PROCESS does not work reliably in some versions of Android, and furthermore does not provide any mechanism for reconciling concurrent modifications across processes. Applications should not attempt to use it. Instead, they should use an explicit cross-process data management approach such as ContentProvider.

SharedPreference loading flag: when set, the file on disk will be checked for modification even if the shared preferences instance is already loaded in this process. This behavior is sometimes desired in cases where the application has multiple processes, all writing to the same SharedPreferences file. Generally there are better forms of communication between processes, though.

This was the legacy (but undocumented) behavior in and before Gingerbread (Android 2.3) and this flag is implied when targetting such releases. For applications targetting SDK versions greater than Android 2.3, this flag must be explicitly set if desired.

Constant Value: 4 (0x00000004)

MODE_NO_LOCALIZED_COLLATORS

int MODE_NO_LOCALIZED_COLLATORS

Database open flag: when set, the database is opened without support for localized collators.

Constant Value: 16 (0x00000010)

MODE_PRIVATE

int MODE_PRIVATE

File creation mode: the default mode, where the created file can only be accessed by the calling application (or all applications sharing the same user ID).

Constant Value: 0 (0x00000000)

MODE_WORLD_READABLE

int MODE_WORLD_READABLE

This constant was deprecated in API level 17.
Creating world-readable files is very dangerous, and likely to cause security holes in applications. It is strongly discouraged; instead, applications should use more formal mechanism for interactions such as ContentProvider, BroadcastReceiver, and Service. There are no guarantees that this access mode will remain on a file, such as when it goes through a backup and restore.

File creation mode: allow all other applications to have read access to the created file.

As of N attempting to use this mode will throw a SecurityException.

Constant Value: 1 (0x00000001)

MODE_WORLD_WRITEABLE

int MODE_WORLD_WRITEABLE

This constant was deprecated in API level 17.
Creating world-writable files is very dangerous, and likely to cause security holes in applications. It is strongly discouraged; instead, applications should use more formal mechanism for interactions such as ContentProvider, BroadcastReceiver, and Service. There are no guarantees that this access mode will remain on a file, such as when it goes through a backup and restore.

File creation mode: allow all other applications to have write access to the created file.

As of N attempting to use this mode will throw a SecurityException.

Constant Value: 2 (0x00000002)

Context

Context ()

bindService

boolean bindService (Intent service, 
                ServiceConnection conn, 
                int flags)

Connect to an application service, creating it if needed. This defines a dependency between your application and the service. The given conn will receive the service object when it is created and be told if it dies and restarts. The service will be considered required by the system only for as long as the calling context exists. For example, if this Context is an Activity that is stopped, the service will not be required to continue running until the Activity is resumed.

This function will throw SecurityException if you do not have permission to bind to the given service.

Note: this method can not be called from a BroadcastReceiver component. A pattern you can use to communicate from a BroadcastReceiver to a Service is to call startService(Intent) with the arguments containing the command to be sent, with the service calling its stopSelf(int) method when done executing that command. See the API demo App/Service/Service Start Arguments Controller for an illustration of this. It is okay, however, to use this method from a BroadcastReceiver that has been registered with registerReceiver(BroadcastReceiver, IntentFilter), since the lifetime of this BroadcastReceiver is tied to another object (the one that registered it).

checkCallingOrSelfPermission

int checkCallingOrSelfPermission (String permission)

Determine whether the calling process of an IPC or you have been granted a particular permission. This is the same as checkCallingPermission(String), except it grants your own permissions if you are not currently processing an IPC. Use with care!

checkCallingOrSelfUriPermission

int checkCallingOrSelfUriPermission (Uri uri, 
                int modeFlags)

Determine whether the calling process of an IPC or you has been granted permission to access a specific URI. This is the same as checkCallingUriPermission(Uri, int), except it grants your own permissions if you are not currently processing an IPC. Use with care!

checkCallingPermission

int checkCallingPermission (String permission)

Determine whether the calling process of an IPC you are handling has been granted a particular permission. This is basically the same as calling checkPermission(String, int, int) with the pid and uid returned by getCallingPid() and getCallingUid(). One important difference is that if you are not currently processing an IPC, this function will always fail. This is done to protect against accidentally leaking permissions; you can use checkCallingOrSelfPermission(String) to avoid this protection.

checkCallingUriPermission

int checkCallingUriPermission (Uri uri, 
                int modeFlags)

Determine whether the calling process and user ID has been granted permission to access a specific URI. This is basically the same as calling checkUriPermission(Uri, int, int, int) with the pid and uid returned by getCallingPid() and getCallingUid(). One important difference is that if you are not currently processing an IPC, this function will always fail.

checkPermission

int checkPermission (String permission, 
                int pid, 
                int uid)

Determine whether the given permission is allowed for a particular process and user ID running in the system.

checkSelfPermission

int checkSelfPermission (String permission)

Determine whether you have been granted a particular permission.

checkUriPermission

int checkUriPermission (Uri uri, 
                String readPermission, 
                String writePermission, 
                int pid, 
                int uid, 
                int modeFlags)

Check both a Uri and normal permission. This allows you to perform both checkPermission(String, int, int) and checkUriPermission(Uri, int, int, int) in one call.

checkUriPermission

int checkUriPermission (Uri uri, 
                int pid, 
                int uid, 
                int modeFlags)

Determine whether a particular process and user ID has been granted permission to access a specific URI. This only checks for permissions that have been explicitly granted -- if the given process/uid has more general access to the URI's content provider then this check will always fail.

clearWallpaper

void clearWallpaper ()

This method was deprecated in API level 5.
Use WallpaperManager.clear() instead.

This method requires the caller to hold the permission SET_WALLPAPER.

createConfigurationContext

Context createConfigurationContext (Configuration overrideConfiguration)

Return a new Context object for the current Context but whose resources are adjusted to match the given Configuration. Each call to this method returns a new instance of a Context object; Context objects are not shared, however common state (ClassLoader, other Resources for the same configuration) may be so the Context itself can be fairly lightweight.

createDeviceProtectedStorageContext

Context createDeviceProtectedStorageContext ()

Return a new Context object for the current Context but whose storage APIs are backed by device-protected storage.

On devices with direct boot, data stored in this location is encrypted with a key tied to the physical device, and it can be accessed immediately after the device has booted successfully, both before and after the user has authenticated with their credentials (such as a lock pattern or PIN).

Because device-protected data is available without user authentication, you should carefully limit the data you store using this Context. For example, storing sensitive authentication tokens or passwords in the device-protected area is strongly discouraged.

If the underlying device does not have the ability to store device-protected and credential-protected data using different keys, then both storage areas will become available at the same time. They remain as two distinct storage locations on disk, and only the window of availability changes.

Each call to this method returns a new instance of a Context object; Context objects are not shared, however common state (ClassLoader, other Resources for the same configuration) may be so the Context itself can be fairly lightweight.

createDisplayContext

Context createDisplayContext (Display display)

Return a new Context object for the current Context but whose resources are adjusted to match the metrics of the given Display. Each call to this method returns a new instance of a Context object; Context objects are not shared, however common state (ClassLoader, other Resources for the same configuration) may be so the Context itself can be fairly lightweight. The returned display Context provides a WindowManager (see getSystemService(String)) that is configured to show windows on the given display. The WindowManager's getDefaultDisplay() method can be used to retrieve the Display from the returned Context.

createPackageContext

Context createPackageContext (String packageName, 
                int flags)

Return a new Context object for the given application name. This Context is the same as what the named application gets when it is launched, containing the same resources and class loader. Each call to this method returns a new instance of a Context object; Context objects are not shared, however they share common state (Resources, ClassLoader, etc) so the Context instance itself is fairly lightweight.

Throws PackageManager.NameNotFoundException if there is no application with the given package name.

Throws SecurityException if the Context requested can not be loaded into the caller's process for security reasons (see CONTEXT_INCLUDE_CODE for more information}.

databaseList

String[] databaseList ()

Returns an array of strings naming the private databases associated with this Context's application package.

deleteDatabase

boolean deleteDatabase (String name)

Delete an existing private SQLiteDatabase associated with this Context's application package.

deleteFile

boolean deleteSharedPreferences (String name)

Delete an existing shared preferences file.

enforceCallingOrSelfPermission

void enforceCallingOrSelfPermission (String permission, 
                String message)

If neither you nor the calling process of an IPC you are handling has been granted a particular permission, throw a SecurityException. This is the same as enforceCallingPermission(String, String), except it grants your own permissions if you are not currently processing an IPC. Use with care!

enforceCallingOrSelfUriPermission

void enforceCallingOrSelfUriPermission (Uri uri, 
                int modeFlags, 
                String message)

If the calling process of an IPC or you has not been granted permission to access a specific URI, throw SecurityException. This is the same as enforceCallingUriPermission(Uri, int, String), except it grants your own permissions if you are not currently processing an IPC. Use with care!

enforceCallingPermission

void enforceCallingPermission (String permission, 
                String message)

If the calling process of an IPC you are handling has not been granted a particular permission, throw a SecurityException. This is basically the same as calling enforcePermission(String, int, int, String) with the pid and uid returned by getCallingPid() and getCallingUid(). One important difference is that if you are not currently processing an IPC, this function will always throw the SecurityException. This is done to protect against accidentally leaking permissions; you can use enforceCallingOrSelfPermission(String, String) to avoid this protection.

enforceCallingUriPermission

void enforceCallingUriPermission (Uri uri, 
                int modeFlags, 
                String message)

If the calling process and user ID has not been granted permission to access a specific URI, throw SecurityException. This is basically the same as calling enforceUriPermission(Uri, int, int, int, String) with the pid and uid returned by getCallingPid() and getCallingUid(). One important difference is that if you are not currently processing an IPC, this function will always throw a SecurityException.

enforcePermission

void enforcePermission (String permission, 
                int pid, 
                int uid, 
                String message)

If the given permission is not allowed for a particular process and user ID running in the system, throw a SecurityException.

enforceUriPermission

void enforceUriPermission (Uri uri, 
                String readPermission, 
                String writePermission, 
                int pid, 
                int uid, 
                int modeFlags, 
                String message)

Enforce both a Uri and normal permission. This allows you to perform both enforcePermission(String, int, int, String) and enforceUriPermission(Uri, int, int, int, String) in one call.

enforceUriPermission

void enforceUriPermission (Uri uri, 
                int pid, 
                int uid, 
                int modeFlags, 
                String message)

If a particular process and user ID has not been granted permission to access a specific URI, throw SecurityException. This only checks for permissions that have been explicitly granted -- if the given process/uid has more general access to the URI's content provider then this check will always fail.

fileList

String[] fileList ()

Returns an array of strings naming the private files associated with this Context's application package.

getApplicationContext

Context getApplicationContext ()

Return the context of the single, global Application object of the current process. This generally should only be used if you need a Context whose lifecycle is separate from the current context, that is tied to the lifetime of the process rather than the current component.

Consider for example how this interacts with registerReceiver(BroadcastReceiver, IntentFilter):

• If used from an Activity context, the receiver is being registered within that activity. This means that you are expected to unregister before the activity is done being destroyed; in fact if you do not do so, the framework will clean up your leaked registration as it removes the activity and log an error. Thus, if you use the Activity context to register a receiver that is static (global to the process, not associated with an Activity instance) then that registration will be removed on you at whatever point the activity you used is destroyed.

• If used from the Context returned here, the receiver is being registered with the global state associated with your application. Thus it will never be unregistered for you. This is necessary if the receiver is associated with static data, not a particular component. However using the ApplicationContext elsewhere can easily lead to serious leaks if you forget to unregister, unbind, etc.

getApplicationInfo

ApplicationInfo getApplicationInfo ()

Return the full application info for this context's package.

getAssets

AssetManager getAssets ()

Returns an AssetManager instance for the application's package.

Note: Implementations of this method should return an AssetManager instance that is consistent with the Resources instance returned by getResources(). For example, they should share the same Configuration object.

getCacheDir

File getCacheDir ()

Returns the absolute path to the application specific cache directory on the filesystem. These files will be ones that get deleted first when the device runs low on storage. There is no guarantee when these files will be deleted.

Note: you should not rely on the system deleting these files for you; you should always have a reasonable maximum, such as 1 MB, for the amount of space you consume with cache files, and prune those files when exceeding that space.

The returned path may change over time if the calling app is moved to an adopted storage device, so only relative paths should be persisted.

Apps require no extra permissions to read or write to the returned path, since this path lives in their private storage.

getClassLoader

ClassLoader getClassLoader ()

Return a class loader you can use to retrieve classes in this package.

getCodeCacheDir

File getCodeCacheDir ()

Returns the absolute path to the application specific cache directory on the filesystem designed for storing cached code. The system will delete any files stored in this location both when your specific application is upgraded, and when the entire platform is upgraded.

This location is optimal for storing compiled or optimized code generated by your application at runtime.

The returned path may change over time if the calling app is moved to an adopted storage device, so only relative paths should be persisted.

Apps require no extra permissions to read or write to the returned path, since this path lives in their private storage.

getColor

int getColor (int id)

Returns a color associated with a particular resource ID and styled for the current theme.

getColorStateList

ColorStateList getColorStateList (int id)

Returns a color state list associated with a particular resource ID and styled for the current theme.

getContentResolver

ContentResolver getContentResolver ()

Return a ContentResolver instance for your application's package.

getDataDir

File getDataDir ()

Returns the absolute path to the directory on the filesystem where all private files belonging to this app are stored. Apps should not use this path directly; they should instead use getFilesDir(), getCacheDir(), getDir(String, int), or other storage APIs on this class.

The returned path may change over time if the calling app is moved to an adopted storage device, so only relative paths should be persisted.

No additional permissions are required for the calling app to read or write files under the returned path.

getDatabasePath

File getDatabasePath (String name)

Returns the absolute path on the filesystem where a database created with openOrCreateDatabase(String, int, SQLiteDatabase.CursorFactory) is stored.

The returned path may change over time if the calling app is moved to an adopted storage device, so only relative paths should be persisted.

getDir

File getDir (String name, 
                int mode)

Retrieve, creating if needed, a new directory in which the application can place its own custom data files. You can use the returned File object to create and access files in this directory. Note that files created through a File object will only be accessible by your own application; you can only set the mode of the entire directory, not of individual files.

The returned path may change over time if the calling app is moved to an adopted storage device, so only relative paths should be persisted.

Apps require no extra permissions to read or write to the returned path, since this path lives in their private storage.

getDrawable

Drawable getDrawable (int id)

Returns a drawable object associated with a particular resource ID and styled for the current theme.

getExternalCacheDir

File getExternalCacheDir ()

Returns absolute path to application-specific directory on the primary shared/external storage device where the application can place cache files it owns. These files are internal to the application, and not typically visible to the user as media.

This is like getCacheDir() in that these files will be deleted when the application is uninstalled, however there are some important differences:

• The platform does not always monitor the space available in shared storage, and thus may not automatically delete these files. Apps should always manage the maximum space used in this location. Currently the only time files here will be deleted by the platform is when running on JELLY_BEAN_MR1 or later and isExternalStorageEmulated(File) returns true.
• Shared storage may not always be available, since removable media can be ejected by the user. Media state can be checked using getExternalStorageState(File).
• There is no security enforced with these files. For example, any application holding WRITE_EXTERNAL_STORAGE can write to these files.

If a shared storage device is emulated (as determined by isExternalStorageEmulated(File)), it's contents are backed by a private user data partition, which means there is little benefit to storing data here instead of the private directory returned by getCacheDir().

Starting in KITKAT, no permissions are required to read or write to the returned path; it's always accessible to the calling app. This only applies to paths generated for package name of the calling application. To access paths belonging to other packages, WRITE_EXTERNAL_STORAGE and/or READ_EXTERNAL_STORAGE are required.

On devices with multiple users (as described by UserManager), each user has their own isolated shared storage. Applications only have access to the shared storage for the user they're running as.

The returned path may change over time if different shared storage media is inserted, so only relative paths should be persisted.

getExternalCacheDirs

File[] getExternalCacheDirs ()

Returns absolute paths to application-specific directories on all shared/external storage devices where the application can place cache files it owns. These files are internal to the application, and not typically visible to the user as media.

This is like getCacheDir() in that these files will be deleted when the application is uninstalled, however there are some important differences:

Currently the only time files here will be deleted by the platform is when running on JELLY_BEAN_MR1 or later and isExternalStorageEmulated(File) returns true.
• Shared storage may not always be available, since removable media can be ejected by the user. Media state can be checked using getExternalStorageState(File).
• There is no security enforced with these files. For example, any application holding WRITE_EXTERNAL_STORAGE can write to these files.

If a shared storage device is emulated (as determined by isExternalStorageEmulated(File)), it's contents are backed by a private user data partition, which means there is little benefit to storing data here instead of the private directory returned by getCacheDir().

Shared storage devices returned here are considered a stable part of the device, including physical media slots under a protective cover. The returned paths do not include transient devices, such as USB flash drives connected to handheld devices.

An application may store data on any or all of the returned devices. For example, an app may choose to store large files on the device with the most available space, as measured by StatFs.

No additional permissions are required for the calling app to read or write files under the returned path. Write access outside of these paths on secondary external storage devices is not available.

The returned paths may change over time if different shared storage media is inserted, so only relative paths should be persisted.

getExternalFilesDir

File getExternalFilesDir (String type)

Returns the absolute path to the directory on the primary shared/external storage device where the application can place persistent files it owns. These files are internal to the applications, and not typically visible to the user as media.

This is like getFilesDir() in that these files will be deleted when the application is uninstalled, however there are some important differences:

• Shared storage may not always be available, since removable media can be ejected by the user. Media state can be checked using getExternalStorageState(File).
• There is no security enforced with these files. For example, any application holding WRITE_EXTERNAL_STORAGE can write to these files.

Starting in KITKAT, no permissions are required to read or write to the returned path; it's always accessible to the calling app. This only applies to paths generated for package name of the calling application. To access paths belonging to other packages, WRITE_EXTERNAL_STORAGE and/or READ_EXTERNAL_STORAGE are required.

On devices with multiple users (as described by UserManager), each user has their own isolated shared storage. Applications only have access to the shared storage for the user they're running as.

The returned path may change over time if different shared storage media is inserted, so only relative paths should be persisted.

Here is an example of typical code to manipulate a file in an application's shared storage:

void createExternalStoragePrivateFile() {
    // Create a path where we will place our private file on external
    // storage.
    File file = new File(getExternalFilesDir(null), "DemoFile.jpg");

    try {
        // Very simple code to copy a picture from the application's
        // resource into the external file.  Note that this code does
        // no error checking, and assumes the picture is small (does not
        // try to copy it in chunks).  Note that if external storage is
        // not currently mounted this will silently fail.
        InputStream is = getResources().openRawResource(R.drawable.balloons);
        OutputStream os = new FileOutputStream(file);
        byte[] data = new byte[is.available()];
        is.read(data);
        os.write(data);
        is.close();
        os.close();
    } catch (IOException e) {
        // Unable to create file, likely because external storage is
        // not currently mounted.
        Log.w("ExternalStorage", "Error writing " + file, e);
    }
}

void deleteExternalStoragePrivateFile() {
    // Get path for the file on external storage.  If external
    // storage is not currently mounted this will fail.
    File file = new File(getExternalFilesDir(null), "DemoFile.jpg");
    if (file != null) {
        file.delete();
    }
}

boolean hasExternalStoragePrivateFile() {
    // Get path for the file on external storage.  If external
    // storage is not currently mounted this will fail.
    File file = new File(getExternalFilesDir(null), "DemoFile.jpg");
    if (file != null) {
        return file.exists();
    }
    return false;
}

If you supply a non-null type to this function, the returned file will be a path to a sub-directory of the given type. Though these files are not automatically scanned by the media scanner, you can explicitly add them to the media database with MediaScannerConnection.scanFile. Note that this is not the same as Environment.getExternalStoragePublicDirectory(), which provides directories of media shared by all applications. The directories returned here are owned by the application, and their contents will be removed when the application is uninstalled. Unlike Environment.getExternalStoragePublicDirectory(), the directory returned here will be automatically created for you.

Here is an example of typical code to manipulate a picture in an application's shared storage and add it to the media database:

void createExternalStoragePrivatePicture() {
    // Create a path where we will place our picture in our own private
    // pictures directory.  Note that we don't really need to place a
    // picture in DIRECTORY_PICTURES, since the media scanner will see
    // all media in these directories; this may be useful with other
    // media types such as DIRECTORY_MUSIC however to help it classify
    // your media for display to the user.
    File path = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
    File file = new File(path, "DemoPicture.jpg");

    try {
        // Very simple code to copy a picture from the application's
        // resource into the external file.  Note that this code does
        // no error checking, and assumes the picture is small (does not
        // try to copy it in chunks).  Note that if external storage is
        // not currently mounted this will silently fail.
        InputStream is = getResources().openRawResource(R.drawable.balloons);
        OutputStream os = new FileOutputStream(file);
        byte[] data = new byte[is.available()];
        is.read(data);
        os.write(data);
        is.close();
        os.close();

        // Tell the media scanner about the new file so that it is
        // immediately available to the user.
        MediaScannerConnection.scanFile(this,
                new String[] { file.toString() }, null,
                new MediaScannerConnection.OnScanCompletedListener() {
            public void onScanCompleted(String path, Uri uri) {
                Log.i("ExternalStorage", "Scanned " + path + ":");
                Log.i("ExternalStorage", "-> uri=" + uri);
            }
        });
    } catch (IOException e) {
        // Unable to create file, likely because external storage is
        // not currently mounted.
        Log.w("ExternalStorage", "Error writing " + file, e);
    }
}

void deleteExternalStoragePrivatePicture() {
    // Create a path where we will place our picture in the user's
    // public pictures directory and delete the file.  If external
    // storage is not currently mounted this will fail.
    File path = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
    if (path != null) {
        File file = new File(path, "DemoPicture.jpg");
        file.delete();
    }
}

boolean hasExternalStoragePrivatePicture() {
    // Create a path where we will place our picture in the user's
    // public pictures directory and check if the file exists.  If
    // external storage is not currently mounted this will think the
    // picture doesn't exist.
    File path = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
    if (path != null) {
        File file = new File(path, "DemoPicture.jpg");
        return file.exists();
    }
    return false;
}

getExternalFilesDirs

File[] getExternalFilesDirs (String type)

Returns absolute paths to application-specific directories on all shared/external storage devices where the application can place persistent files it owns. These files are internal to the application, and not typically visible to the user as media.

This is like getFilesDir() in that these files will be deleted when the application is uninstalled, however there are some important differences:

No additional permissions are required for the calling app to read or write files under the returned path. Write access outside of these paths on secondary external storage devices is not available.

The returned path may change over time if different shared storage media is inserted, so only relative paths should be persisted.

getExternalMediaDirs

File[] getExternalMediaDirs ()

Returns absolute paths to application-specific directories on all shared/external storage devices where the application can place media files. These files are scanned and made available to other apps through MediaStore.

This is like getExternalFilesDirs(String) in that these files will be deleted when the application is uninstalled, however there are some important differences:

• Shared storage may not always be available, since removable media can be ejected by the user. Media state can be checked using getExternalStorageState(File).

The returned paths may change over time if different shared storage media is inserted, so only relative paths should be persisted.

getFileStreamPath

File getFileStreamPath (String name)

Returns the absolute path on the filesystem where a file created with openFileOutput(String, int) is stored.

The returned path may change over time if the calling app is moved to an adopted storage device, so only relative paths should be persisted.

getFilesDir

File getFilesDir ()

Returns the absolute path to the directory on the filesystem where files created with openFileOutput(String, int) are stored.

The returned path may change over time if the calling app is moved to an adopted storage device, so only relative paths should be persisted.

No additional permissions are required for the calling app to read or write files under the returned path.

getMainLooper

Looper getMainLooper ()

Return the Looper for the main thread of the current process. This is the thread used to dispatch calls to application components (activities, services, etc).

By definition, this method returns the same result as would be obtained by calling Looper.getMainLooper().

getNoBackupFilesDir

File getNoBackupFilesDir ()

Returns the absolute path to the directory on the filesystem similar to getFilesDir(). The difference is that files placed under this directory will be excluded from automatic backup to remote storage. See BackupAgent for a full discussion of the automatic backup mechanism in Android.

The returned path may change over time if the calling app is moved to an adopted storage device, so only relative paths should be persisted.

No additional permissions are required for the calling app to read or write files under the returned path.

getObbDir

File getObbDir ()

Return the primary shared/external storage directory where this application's OBB files (if there are any) can be found. Note if the application does not have any OBB files, this directory may not exist.

This is like getFilesDir() in that these files will be deleted when the application is uninstalled, however there are some important differences:

• Shared storage may not always be available, since removable media can be ejected by the user. Media state can be checked using getExternalStorageState(File).
• There is no security enforced with these files. For example, any application holding WRITE_EXTERNAL_STORAGE can write to these files.

To access paths belonging to other packages, WRITE_EXTERNAL_STORAGE and/or READ_EXTERNAL_STORAGE are required.

On devices with multiple users (as described by UserManager), multiple users may share the same OBB storage location. Applications should ensure that multiple instances running under different users don't interfere with each other.

getObbDirs

File[] getObbDirs ()

Returns absolute paths to application-specific directories on all shared/external storage devices where the application's OBB files (if there are any) can be found. Note if the application does not have any OBB files, these directories may not exist.

No additional permissions are required for the calling app to read or write files under the returned path. Write access outside of these paths on secondary external storage devices is not available.

getPackageCodePath

String getPackageCodePath ()

Return the full path to this context's primary Android package. The Android package is a ZIP file which contains application's primary code and assets.

Note: this is not generally useful for applications, since they should not be directly accessing the file system.

getPackageManager

PackageManager getPackageManager ()

Return PackageManager instance to find global package information.

getPackageName

String getPackageName ()

Return the name of this application's package.

getPackageResourcePath

String getPackageResourcePath ()

Note: this is not generally useful for applications, since they should not be directly accessing the file system.

getResources

Resources getResources ()

Returns a Resources instance for the application's package.

Note: Implementations of this method should return a Resources instance that is consistent with the AssetManager instance returned by getAssets(). For example, they should share the same Configuration object.

getSharedPreferences

SharedPreferences getSharedPreferences (String name, 
                int mode)

Retrieve and hold the contents of the preferences file 'name', returning a SharedPreferences through which you can retrieve and modify its values. Only one instance of the SharedPreferences object is returned to any callers for the same name, meaning they will see each other's edits as soon as they are made.

getString

String getString (int resId, 
                Object... formatArgs)

Returns a localized formatted string from the application's package's default string table, substituting the format arguments as defined in Formatter and format(String, Object...).

Note: System services obtained via this API may be closely associated with the Context in which they are obtained from. In general, do not share the service objects between various different contexts (Activities, Applications, Services, Providers, etc.)

getSystemService

Object getSystemService (String name)

Return the handle to a system-level service by name. The class of the returned object varies by the requested name. Currently available names are:

getSystemServiceName

String getSystemServiceName (Class<?> serviceClass)

Gets the name of the system-level service that is represented by the specified class.

getText

CharSequence getText (int resId)

grantUriPermission

void grantUriPermission (String toPackage, 
                Uri uri, 
                int modeFlags)

Grant permission to access a specific Uri to another package, regardless of whether that package has general permission to access the Uri's content provider. This can be used to grant specific, temporary permissions, typically in response to user interaction (such as the user opening an attachment that you would like someone else to display).

Normally you should use Intent.FLAG_GRANT_READ_URI_PERMISSION or Intent.FLAG_GRANT_WRITE_URI_PERMISSION with the Intent being used to start an activity instead of this function directly. If you use this function directly, you should be sure to call revokeUriPermission(Uri, int) when the target should no longer be allowed to access it.

To succeed, the content provider owning the Uri must have set the grantUriPermissions attribute in its manifest or included the <grant-uri-permissions> tag.

isDeviceProtectedStorage

boolean isDeviceProtectedStorage ()

Indicates if the storage APIs of this Context are backed by device-protected storage.

boolean isRestricted ()

Indicates whether this Context is restricted.

moveDatabaseFrom

boolean moveDatabaseFrom (Context sourceContext, 
                String name)

moveSharedPreferencesFrom

boolean moveSharedPreferencesFrom (Context sourceContext, 
                String name)

Move an existing shared preferences file from the given source storage context to this context. This is typically used to migrate data between storage locations after an upgrade, such as moving to device protected storage.

peekWallpaper

Drawable peekWallpaper ()

This method was deprecated in API level 5.
Use WallpaperManager.peek() instead.

registerComponentCallbacks

void registerComponentCallbacks (ComponentCallbacks callback)

Add a new ComponentCallbacks to the base application of the Context, which will be called at the same times as the ComponentCallbacks methods of activities and other components are called. Note that you must be sure to use unregisterComponentCallbacks(ComponentCallbacks) when appropriate in the future; this will not be removed for you.

registerReceiver

Intent registerReceiver (BroadcastReceiver receiver, 
                IntentFilter filter)

Register a BroadcastReceiver to be run in the main activity thread. The receiver will be called with any broadcast Intent that matches filter, in the main application thread.

The system may broadcast Intents that are "sticky" -- these stay around after the broadcast as finished, to be sent to any later registrations. If your IntentFilter matches one of these sticky Intents, that Intent will be returned by this function and sent to your receiver as if it had just been broadcast.

There may be multiple sticky Intents that match filter, in which case each of these will be sent to receiver. In this case, only one of these can be returned directly by the function; which of these that is returned is arbitrarily decided by the system.

If you know the Intent your are registering for is sticky, you can supply null for your receiver. In this case, no receiver is registered -- the function simply returns the sticky Intent that matches filter. In the case of multiple matches, the same rules as described above apply.

See BroadcastReceiver for more information on Intent broadcasts.

As of ICE_CREAM_SANDWICH, receivers registered with this method will correctly respect the setPackage(String) specified for an Intent being broadcast. Prior to that, it would be ignored and delivered to all matching registered receivers. Be careful if using this for security.

Note: this method cannot be called from a BroadcastReceiver component; that is, from a BroadcastReceiver that is declared in an application's manifest. It is okay, however, to call this method from another BroadcastReceiver that has itself been registered at run time with registerReceiver(BroadcastReceiver, IntentFilter), since the lifetime of such a registered BroadcastReceiver is tied to the object that registered it.

registerReceiver

Intent registerReceiver (BroadcastReceiver receiver, 
                IntentFilter filter, 
                String broadcastPermission, 
                Handler scheduler)

Register to receive intent broadcasts, to run in the context of scheduler. See registerReceiver(BroadcastReceiver, IntentFilter) for more information. This allows you to enforce permissions on who can broadcast intents to your receiver, or have the receiver run in a different thread than the main application thread.

removeStickyBroadcast

void removeStickyBroadcast (Intent intent)

This method was deprecated in API level 21.
Sticky broadcasts should not be used. They provide no security (anyone can access them), no protection (anyone can modify them), and many other problems. The recommended pattern is to use a non-sticky broadcast to report that something has changed, with another mechanism for apps to retrieve the current value whenever desired.
