SearchRecentSuggestionsProvider

public class SearchRecentSuggestionsProvider
extends ContentProvider

java.lang.Object
↳	android.content.ContentProvider
	↳	android.content.SearchRecentSuggestionsProvider

This superclass can be used to create a simple search suggestions provider for your application. It creates suggestions (as the user types) based on recent queries and/or recent views.

In order to use this class, you must do the following.

Implement and test query search, as described in SearchManager. (This provider will send any suggested queries via the standard ACTION_SEARCH Intent, which you'll already support once you have implemented and tested basic searchability.)
Create a Content Provider within your application by extending SearchRecentSuggestionsProvider. The class you create will be very simple - typically, it will have only a constructor. But the constructor has a very important responsibility: When it calls setupSuggestions(String, int), it configures the provider to match the requirements of your searchable activity.

Create a manifest entry describing your provider. Typically this would be as simple as adding the following lines:

     <!-- Content provider for search suggestions -->
     <provider android:name="YourSuggestionProviderClass"
               android:authorities="your.suggestion.authority" />

Please note that you do not instantiate this content provider directly from within your code. This is done automatically by the system Content Resolver, when the search dialog looks for suggestions.
In order for the Content Resolver to do this, you must update your searchable activity's XML configuration file with information about your content provider. The following additions are usually sufficient:
```
     android:searchSuggestAuthority="your.suggestion.authority"
     android:searchSuggestSelection=" ? "
```
In your searchable activities, capture any user-generated queries and record them for future searches by calling SearchRecentSuggestions.saveRecentQuery().

Inherited methods

From class android.content.ContentProvider

`ContentProviderResult[]`	`applyBatch(ArrayList<ContentProviderOperation> operations)` Override this to handle requests to perform a batch of operations, or the default implementation will iterate over the operations and call `apply(ContentProvider, ContentProviderResult[], int)` on each of them.
`void`	`attachInfo(Context context, ProviderInfo info)` After being instantiated, this is called to tell the content provider about itself.
`int`	`bulkInsert(Uri uri, ContentValues[] values)` Override this to handle requests to insert a set of new rows, or the default implementation will iterate over the values and call `insert(Uri, ContentValues)` on each of them.
`Bundle`	`call(String method, String arg, Bundle extras)` Call a provider-defined method.
`Uri`	`canonicalize(Uri url)` Implement this to support canonicalization of URIs that refer to your content provider.
`abstract int`	`delete(Uri uri, String selection, String[] selectionArgs)` Implement this to handle requests to delete one or more rows.
`void`	`dump(FileDescriptor fd, PrintWriter writer, String[] args)` Print the Provider's state into the given stream.
`final String`	`getCallingPackage()` Return the package name of the caller that initiated the request being processed on the current thread.
`final Context`	`getContext()` Retrieves the Context this provider is running in.
`final PathPermission[]`	`getPathPermissions()` Return the path-based permissions required for read and/or write access to this content provider.
`final String`	`getReadPermission()` Return the name of the permission required for read-only access to this content provider.
`String[]`	`getStreamTypes(Uri uri, String mimeTypeFilter)` Called by a client to determine the types of data streams that this content provider supports for the given URI.
`abstract String`	`getType(Uri uri)` Implement this to handle requests for the MIME type of the data at the given URI.
`final String`	`getWritePermission()` Return the name of the permission required for read/write access to this content provider.
`abstract Uri`	`insert(Uri uri, ContentValues values)` Implement this to handle requests to insert a new row.
`boolean`	`isTemporary()` Returns true if this instance is a temporary content provider.
`void`	`onConfigurationChanged(Configuration newConfig)` Called by the system when the device configuration changes while your component is running. This method is always called on the application main thread, and must not perform lengthy operations.
`abstract boolean`	`onCreate()` Implement this to initialize your content provider on startup.
`void`	`onLowMemory()` This is called when the overall system is running low on memory, and actively running processes should trim their memory usage. This method is always called on the application main thread, and must not perform lengthy operations.
`void`	`onTrimMemory(int level)` Called when the operating system has determined that it is a good time for a process to trim unneeded memory from its process.
`AssetFileDescriptor`	`openAssetFile(Uri uri, String mode, CancellationSignal signal)` This is like `openFile(Uri, String)`, but can be implemented by providers that need to be able to return sub-sections of files, often assets inside of their .apk.
`AssetFileDescriptor`	`openAssetFile(Uri uri, String mode)` This is like `openFile(Uri, String)`, but can be implemented by providers that need to be able to return sub-sections of files, often assets inside of their .apk.
`ParcelFileDescriptor`	`openFile(Uri uri, String mode, CancellationSignal signal)` Override this to handle requests to open a file blob.
`ParcelFileDescriptor`	`openFile(Uri uri, String mode)` Override this to handle requests to open a file blob.
`final ParcelFileDescriptor`	`openFileHelper(Uri uri, String mode)` Convenience for subclasses that wish to implement `openFile(Uri, String)` by looking up a column named "_data" at the given URI.
`<T> ParcelFileDescriptor`	`openPipeHelper(Uri uri, String mimeType, Bundle opts, T args, PipeDataWriter<T> func)` A helper function for implementing `openTypedAssetFile(Uri, String, Bundle)`, for creating a data pipe and background thread allowing you to stream generated data back to the client.
`AssetFileDescriptor`	`openTypedAssetFile(Uri uri, String mimeTypeFilter, Bundle opts)` Called by a client to open a read-only stream containing data of a particular MIME type.
`AssetFileDescriptor`	`openTypedAssetFile(Uri uri, String mimeTypeFilter, Bundle opts, CancellationSignal signal)` Called by a client to open a read-only stream containing data of a particular MIME type.
