![]() java.lang.Object
|
String ANY_CURSOR_ITEM_TYPE
This is the Android platform's generic MIME type to match any MIME type of the form "CURSOR_ITEM_BASE_TYPE
/SUB_TYPE
". SUB_TYPE
is the sub-type of the application-dependent content, e.g., "audio", "video", "playlist".
Constant Value: "vnd.android.cursor.item/*"
String CURSOR_DIR_BASE_TYPE
This is the Android platform's base MIME type for a content: URI containing a Cursor of zero or more items. Applications should use this as the base type along with their own sub-type of their content: URIs that represent a directory of items. For example, hypothetical IMAP email client may have a URI content://com.company.provider.imap/inbox
for all of the messages in its inbox, whose MIME type would be reported as CURSOR_DIR_BASE_TYPE + "/vnd.company.imap-msg"
Note how the base MIME type varies between this and CURSOR_ITEM_BASE_TYPE
depending on whether there is one single item or multiple items in the data set, while the sub-type remains the same because in either case the data structure contained in the cursor is the same.
Constant Value: "vnd.android.cursor.dir"
String CURSOR_ITEM_BASE_TYPE
This is the Android platform's base MIME type for a content: URI containing a Cursor of a single item. Applications should use this as the base type along with their own sub-type of their content: URIs that represent a particular item. For example, hypothetical IMAP email client may have a URI content://com.company.provider.imap/inbox/1
for a particular message in the inbox, whose MIME type would be reported as CURSOR_ITEM_BASE_TYPE + "/vnd.company.imap-msg"
Compare with CURSOR_DIR_BASE_TYPE
.
Constant Value: "vnd.android.cursor.item"
String EXTRA_SIZE
An extra Point
describing the optimal size for a requested image resource, in pixels. If a provider has multiple sizes of the image, it should return the image closest to this size.
See also:
Constant Value: "android.content.extra.SIZE"
int NOTIFY_SKIP_NOTIFY_FOR_DESCENDANTS
Flag for notifyChange(Uri, ContentObserver, int)
: if set, this notification will be skipped if it is being delivered to the root URI of a ContentObserver that is using "notify for descendants." The purpose of this is to allow the provide to send a general notification of "something under X" changed that observers of that specific URI can receive, while also sending a specific URI under X. It would use this flag when sending the former, so that observers of "X and descendants" only see the latter.
Constant Value: 2 (0x00000002)
int NOTIFY_SYNC_TO_NETWORK
Flag for notifyChange(Uri, ContentObserver, int)
: attempt to sync the change to the network.
Constant Value: 1 (0x00000001)
String SCHEME_ANDROID_RESOURCE
Constant Value: "android.resource"
String SYNC_EXTRAS_ACCOUNT
This constant was deprecated in API level 5.
instead use requestSync(android.accounts.Account, String, android.os.Bundle)
Constant Value: "account"
String SYNC_EXTRAS_DISCARD_LOCAL_DELETIONS
Indicates that the sync adapter should not proceed with the delete operations, if it determines that there are too many. See tooManyDeletions
Constant Value: "discard_deletions"
String SYNC_EXTRAS_DO_NOT_RETRY
If this extra is set to true then the request will not be retried if it fails.
Constant Value: "do_not_retry"
String SYNC_EXTRAS_EXPEDITED
If this extra is set to true, the sync request will be scheduled at the front of the sync request queue and without any delay
Constant Value: "expedited"
String SYNC_EXTRAS_FORCE
This constant was deprecated in API level 5.
instead use SYNC_EXTRAS_MANUAL
Constant Value: "force"
String SYNC_EXTRAS_IGNORE_BACKOFF
If this extra is set to true then any backoffs for the initial attempt (e.g. due to retries) are ignored by the sync scheduler. If this request fails and gets rescheduled then the retries will still honor the backoff.
Constant Value: "ignore_backoff"
String SYNC_EXTRAS_IGNORE_SETTINGS
If this extra is set to true then the sync settings (like getSyncAutomatically()) are ignored by the sync scheduler.
Constant Value: "ignore_settings"
String SYNC_EXTRAS_INITIALIZE
Set by the SyncManager to request that the SyncAdapter initialize itself for the given account/authority pair. One required initialization step is to ensure that setIsSyncable(android.accounts.Account, String, int)
has been called with a >= 0 value. When this flag is set the SyncAdapter does not need to do a full sync, though it is allowed to do so.
Constant Value: "initialize"
String SYNC_EXTRAS_MANUAL
Setting this extra is the equivalent of setting both SYNC_EXTRAS_IGNORE_SETTINGS
and SYNC_EXTRAS_IGNORE_BACKOFF
Constant Value: "force"
String SYNC_EXTRAS_OVERRIDE_TOO_MANY_DELETIONS
Indicates that the sync adapter should proceed with the delete operations, even if it determines that there are too many. See tooManyDeletions
Constant Value: "deletions_override"
String SYNC_EXTRAS_REQUIRE_CHARGING
If this extra is set to true, the sync request will be scheduled only when the device is plugged in. This is equivalent to calling setRequiresCharging(true) on SyncRequest
.
Constant Value: "require_charging"
String SYNC_EXTRAS_UPLOAD
Indicates that this sync is intended to only upload local changes to the server. For example, this will be set to true if the sync is initiated by a call to notifyChange(android.net.Uri, android.database.ContentObserver, boolean)
Constant Value: "upload"
int SYNC_OBSERVER_TYPE_ACTIVE
Constant Value: 4 (0x00000004)
int SYNC_OBSERVER_TYPE_PENDING
Constant Value: 2 (0x00000002)
int SYNC_OBSERVER_TYPE_SETTINGS
Constant Value: 1 (0x00000001)
ContentProviderClient acquireContentProviderClient (Uri uri)
Returns a ContentProviderClient
that is associated with the ContentProvider
that services the content at uri, starting the provider if necessary. Returns null if there is no provider associated wih the uri. The caller must indicate that they are done with the provider by calling release()
which will allow the system to release the provider it it determines that there is no other reason for keeping it active.
Parameters | |
---|---|
uri |
Uri : specifies which provider should be acquired |
Returns | |
---|---|
ContentProviderClient |
a ContentProviderClient that is associated with the ContentProvider that services the content at uri or null if there isn't one. |
ContentProviderClient acquireContentProviderClient (String name)
Returns a ContentProviderClient
that is associated with the ContentProvider
with the authority of name, starting the provider if necessary. Returns null if there is no provider associated wih the uri. The caller must indicate that they are done with the provider by calling release()
which will allow the system to release the provider it it determines that there is no other reason for keeping it active.
Parameters | |
---|---|
name |
String : specifies which provider should be acquired |
Returns | |
---|---|
ContentProviderClient |
a ContentProviderClient that is associated with the ContentProvider with the authority of name or null if there isn't one. |
ContentProviderClient acquireUnstableContentProviderClient (String name)
Like acquireContentProviderClient(String)
, but for use when you do not trust the stability of the target content provider. This turns off the mechanism in the platform clean up processes that are dependent on a content provider if that content provider's process goes away. Normally you can safely assume that once you have acquired a provider, you can freely use it as needed and it won't disappear, even if your process is in the background. If using this method, you need to take care to deal with any failures when communicating with the provider, and be sure to close it so that it can be re-opened later. In particular, catching a DeadObjectException
from the calls there will let you know that the content provider has gone away; at that point the current ContentProviderClient object is invalid, and you should release it. You can acquire a new one if you would like to try to restart the provider and perform new operations on it.
Parameters | |
---|---|
name |
String
|
Returns | |
---|---|
ContentProviderClient |
ContentProviderClient acquireUnstableContentProviderClient (Uri uri)

void addPeriodicSync (Account account, String authority, Bundle extras, long pollFrequency)
Specifies that a sync should be requested with the specified the account, authority, and extras at the given frequency. If there is already another periodic sync scheduled with the account, authority and extras then a new periodic sync won't be added, instead the frequency of the previous one will be updated.
These periodic syncs honor the "syncAutomatically" and "masterSyncAutomatically" settings. Although these sync are scheduled at the specified frequency, it may take longer for it to actually be started if other syncs are ahead of it in the sync operation queue. This means that the actual start time may drift.
Periodic syncs are not allowed to have any of SYNC_EXTRAS_DO_NOT_RETRY
, SYNC_EXTRAS_IGNORE_BACKOFF
, SYNC_EXTRAS_IGNORE_SETTINGS
, SYNC_EXTRAS_INITIALIZE
, SYNC_EXTRAS_FORCE
, SYNC_EXTRAS_EXPEDITED
, SYNC_EXTRAS_MANUAL
set to true. If any are supplied then an IllegalArgumentException
will be thrown.
This method requires the caller to hold the permission WRITE_SYNC_SETTINGS
.
The bundle for a periodic sync can be queried by applications with the correct permissions using getPeriodicSyncs(Account, String)
, so no sensitive data should be transferred here.
Parameters | |
---|---|
account |
Account : the account to specify in the sync |
authority |
String : the provider to specify in the sync request |
extras |
Bundle : extra parameters to go along with the sync request |
pollFrequency |
long : how frequently the sync should be performed, in seconds. A minimum value of 1 hour is enforced. |
Throws | |
---|---|
IllegalArgumentException |
if an illegal extra was set or if any of the parameters are null. |
Object addStatusChangeListener (int mask, SyncStatusObserver callback)
Request notifications when the different aspects of the SyncManager change. The different items that can be requested are:
The caller can set one or more of the status types in the mask for any given listener registration.Parameters | |
---|---|
mask |
int : the status change types that will cause the callback to be invoked |
callback |
SyncStatusObserver : observer to be invoked when the status changes |
Returns | |
---|---|
Object |
a handle that can be used to remove the listener at a later time |
ContentProviderResult[] applyBatch (String authority, ArrayList<ContentProviderOperation> operations)
Applies each of the ContentProviderOperation
objects and returns an array of their results. Passes through OperationApplicationException, which may be thrown by the call to apply(ContentProvider, ContentProviderResult[], int)
. If all the applications succeed then a ContentProviderResult
array with the same number of elements as the operations will be returned. It is implementation-specific how many, if any, operations will have been successfully applied if a call to apply results in a OperationApplicationException
.
Parameters | |
---|---|
authority |
String : the authority of the ContentProvider to which this batch should be applied |
operations |
ArrayList : the operations to apply |
Returns | |
---|---|
ContentProviderResult[] |
the results of the applications |
Throws | |
---|---|
OperationApplicationException |
thrown if an application fails. See apply(ContentProvider, ContentProviderResult[], int) for more information. |
RemoteException |
thrown if a RemoteException is encountered while attempting to communicate with a remote provider. |
int bulkInsert (Uri url, ContentValues[] values)
Inserts multiple rows into a table at the given URL. This function make no guarantees about the atomicity of the insertions.
Parameters | |
---|---|
url |
Uri : The URL of the table to insert into. |
values |
ContentValues : The initial values for the newly inserted rows. The key is the column name for the field. Passing null will create an empty row. |
Returns | |
---|---|
int |
the number of newly created rows. |
Bundle call (Uri uri, String method, String arg, Bundle extras)
Call a provider-defined method. This can be used to implement read or write interfaces which are cheaper than using a Cursor and/or do not fit into the traditional table model.
Parameters | |
---|---|
uri |
Uri
|
method |
String : provider-defined method name to call. Opaque to framework, but must be non-null. |
arg |
String : provider-defined String argument. May be null. |
extras |
Bundle : provider-defined Bundle argument. May be null. |
Returns | |
---|---|
Bundle |
a result Bundle, possibly null. Will be null if the ContentProvider does not implement call. |
Throws | |
---|---|
NullPointerException |
if uri or method is null |
IllegalArgumentException |
if uri is not known |
void cancelSync (Uri uri)
This method was deprecated in API level 5.
instead use cancelSync(android.accounts.Account, String)
Cancel any active or pending syncs that match the Uri. If the uri is null then all syncs will be canceled.
Parameters | |
---|---|
uri |
Uri : the uri of the provider to sync or null to sync all providers. |
void cancelSync (SyncRequest request)
Remove the specified sync. This will cancel any pending or active syncs. If the request is for a periodic sync, this call will remove any future occurrences.
If a periodic sync is specified, the caller must hold the permission WRITE_SYNC_SETTINGS
.
Parameters | |
---|---|
request |
SyncRequest : SyncRequest object containing information about sync to cancel. |
void cancelSync (Account account, String authority)
Cancel any active or pending syncs that match account and authority. The account and authority can each independently be set to null, which means that syncs with any account or authority, respectively, will match.
Parameters | |
---|---|
account |
Account : filters the syncs that match by this account |
authority |
String : filters the syncs that match by this authority |
Uri canonicalize (Uri url)
Transform the given url to a canonical representation of its referenced resource, which can be used across devices, persisted, backed up and restored, etc. The returned Uri is still a fully capable Uri for use with its content provider, allowing you to do all of the same content provider operations as with the original Uri -- query(Uri, String[], String, String[], String)
, openInputStream(android.net.Uri)
, etc. The only difference in behavior between the original and new Uris is that the content provider may need to do some additional work at each call using it to resolve it to the correct resource, especially if the canonical Uri has been moved to a different environment.
If you are moving a canonical Uri between environments, you should perform another call to canonicalize(Uri)
with that original Uri to re-canonicalize it for the current environment. Alternatively, you may want to use uncanonicalize(Uri)
to transform it to a non-canonical Uri that works only in the current environment but potentially more efficiently than the canonical representation.
Parameters | |
---|---|
url |
Uri : The Uri that is to be transformed to a canonical representation. Like all resolver calls, the input can be either a non-canonical or canonical Uri. |
Returns | |
---|---|
Uri |
Returns the official canonical representation of url, or null if the content provider does not support a canonical representation of the given Uri. Many providers may not support canonicalization of some or all of their Uris. |
See also:
int delete (Uri url, String where, String[] selectionArgs)
Deletes row(s) specified by a content URI. If the content provider supports transactions, the deletion will be atomic.
Parameters | |
---|---|
url |
Uri : The URL of the row to delete. |
where |
String : A filter to apply to rows before deleting, formatted as an SQL WHERE clause (excluding the WHERE itself). |
selectionArgs |
String
|
Returns | |
---|---|
int |
The number of rows deleted. |
SyncInfo getCurrentSync ()
This method was deprecated in API level 11.
Since multiple concurrent syncs are now supported you should use getCurrentSyncs()
to get the accurate list of current syncs. This method returns the first item from the list of current syncs or null if there are none.
If a sync is active returns the information about it, otherwise returns null.
This method requires the caller to hold the permission READ_SYNC_STATS
.

This method requires the caller to hold the permission READ_SYNC_STATS
.
Returns | |
---|---|
List<SyncInfo> |
a List of SyncInfo objects for the currently active syncs. |
int getIsSyncable (Account account, String authority)

Returns | |
---|---|
List<UriPermission> |
List<PeriodicSync> getPeriodicSyncs (Account account, String authority)
Get the list of information about the periodic syncs for the given account and authority.

void notifyChange (Uri uri, ContentObserver observer, boolean syncToNetwork)
Notify registered observers that a row was updated. To register, call registerContentObserver()
. By default, CursorAdapter objects will get this notification. If syncToNetwork is true, this will attempt to schedule a local sync using the sync adapter that's registered for the authority of the provided uri. No account will be passed to the sync adapter, so all matching accounts will be synchronized.
Parameters | |
---|---|
uri |
Uri : The uri of the content that was changed. |
observer |
ContentObserver : The observer that originated the change, may be null. The observer that originated the change will only receive the notification if it has requested to receive self-change notifications by implementing |

boolean : If true, same as NOTIFY_SYNC_TO_NETWORK . |
void notifyChange (Uri uri, ContentObserver observer, int flags)
Notify registered observers that a row was updated. To register, call registerContentObserver()
. By default, CursorAdapter objects will get this notification. If syncToNetwork is true, this will attempt to schedule a local sync using the sync adapter that's registered for the authority of the provided uri. No account will be passed to the sync adapter, so all matching accounts will be synchronized.
Parameters | |
---|---|
uri |
Uri : The uri of the content that was changed. |

AssetFileDescriptor openAssetFileDescriptor (Uri uri, String mode, CancellationSignal cancellationSignal)
Open a raw file descriptor to access data under a URI. This interacts with the underlying openAssetFile(Uri, String)
method of the provider associated with the given URI, to retrieve any file stored there.
SCHEME_CONTENT
)SCHEME_ANDROID_RESOURCE
)SCHEME_FILE
)SCHEME_ANDROID_RESOURCE
) SchemeA Uri object can be used to reference a resource in an APK file. The Uri should be one of the following formats:
android.resource://package_name/id_number
package_name
is your package name as listed in your AndroidManifest.xml. For example com.example.myapp
id_number
is the int form of the ID.Uri uri = Uri.parse("android.resource://com.example.myapp/" + R.raw.my_resource");
android.resource://package_name/type/name
package_name
is your package name as listed in your AndroidManifest.xml. For example com.example.myapp
type
is the string form of the resource type. For example, raw
or drawable
. name
is the string form of the resource name. That is, whatever the file name was in your res directory, without the type extension. The easiest way to construct this form is Uri uri = Uri.parse("android.resource://com.example.myapp/raw/my_resource");
Note that if this function is called for read-only input (mode is "r") on a content: URI, it will instead call openTypedAssetFileDescriptor(Uri, String, Bundle)
for you with a MIME type of "*/*". This allows such callers to benefit from any built-in data conversion that a provider implements.
Parameters | |
---|---|
uri |
Uri : The desired URI to open. |
mode |
String : The file mode to use, as per ContentProvider.openAssetFile . |
cancellationSignal |
CancellationSignal : A signal to cancel the operation in progress, or null if none. If the operation is canceled, then OperationCanceledException will be thrown. |
Returns | |
---|---|
AssetFileDescriptor |
Returns a new ParcelFileDescriptor pointing to the file. You own this descriptor and are responsible for closing it when done. |
Throws | |
---|---|
FileNotFoundException |
Throws FileNotFoundException of no file exists under the URI or the mode is invalid. |

ParcelFileDescriptor openFileDescriptor (Uri uri, String mode, CancellationSignal cancellationSignal)
Open a raw file descriptor to access data under a URI. This is like openAssetFileDescriptor(Uri, String)
, but uses the underlying openFile(Uri, String)
ContentProvider.openFile()} method, so will not work with providers that return sub-sections of files. If at all possible, you should use openAssetFileDescriptor(Uri, String)
. You will receive a FileNotFoundException exception if the provider returns a sub-section of a file.
SCHEME_CONTENT
)SCHEME_FILE
)See openAssetFileDescriptor(Uri, String)
for more information on these schemes.
If opening with the exclusive "r" or "w" modes, the returned ParcelFileDescriptor could be a pipe or socket pair to enable streaming of data. Opening with the "rw" mode implies a file on disk that supports seeking. If possible, always use an exclusive mode to give the underlying ContentProvider
the most flexibility.
If you are writing a file, and need to communicate an error to the provider, use closeWithError(String)
.
Parameters | |
---|---|
uri |
Uri : The desired URI to open. |
mode |
String : The file mode to use, as per ContentProvider.openFile . |
cancellationSignal |
CancellationSignal : A signal to cancel the operation in progress, or null if none. If the operation is canceled, then OperationCanceledException will be thrown. |
Returns | |

AssetFileDescriptor openTypedAssetFileDescriptor (Uri uri, String mimeType, Bundle opts, CancellationSignal cancellationSignal)
Open a raw file descriptor to access (potentially type transformed) data from a "content:" URI. This interacts with the underlying openTypedAssetFile(Uri, String, Bundle)
method of the provider associated with the given URI, to retrieve retrieve any appropriate data stream for the data stored there.
Unlike openAssetFileDescriptor(Uri, String)
, this function only works with "content:" URIs, because content providers are the only facility with an associated MIME type to ensure that the returned data stream is of the desired type.
All text/* streams are encoded in UTF-8.
Parameters | |
---|---|
uri |
Uri : The desired URI to open. |
mimeType |
String : The desired MIME type of the returned data. This can be a pattern such as */*, which will allow the content provider to select a type, though there is no way for you to determine what type it is returning. |
opts |
Bundle : Additional provider-dependent options. |
cancellationSignal |
CancellationSignal : A signal to cancel the operation in progress, or null if none. If the operation is canceled, then OperationCanceledException will be thrown. |
Returns | |
---|---|
AssetFileDescriptor |
Returns a new ParcelFileDescriptor from which you can read the data stream from the provider. Note that this may be a pipe, meaning you can't seek in it. The only seek you should do is if the AssetFileDescriptor contains an offset, to move to that offset before reading. You own this descriptor and are responsible for closing it when done. |
Throws | |
---|---|
FileNotFoundException |
Throws FileNotFoundException of no data of the desired type exists under the URI. |
AssetFileDescriptor openTypedAssetFileDescriptor (Uri uri, String mimeType, Bundle opts)
