AppWidgetProvider

public class AppWidgetProvider
extends BroadcastReceiver

java.lang.Object
↳	android.content.BroadcastReceiver
	↳	android.appwidget.AppWidgetProvider

A convenience class to aid in implementing an AppWidget provider. Everything you can do with AppWidgetProvider, you can do with a regular BroadcastReceiver. AppWidgetProvider merely parses the relevant fields out of the Intent that is received in onReceive(Context,Intent), and calls hook methods with the received extras.

Extend this class and override one or more of the onUpdate(Context, AppWidgetManager, int[]), onDeleted(Context, int[]), onEnabled(Context) or onDisabled(Context) methods to implement your own AppWidget functionality.

Summary

Public constructors
`AppWidgetProvider()` Constructor to initialize AppWidgetProvider.

Public methods
`void`	`onAppWidgetOptionsChanged(Context context, AppWidgetManager appWidgetManager, int appWidgetId, Bundle newOptions)` Called in response to the `ACTION_APPWIDGET_OPTIONS_CHANGED` broadcast when this widget has been layed out at a new size.
`void`	`onDeleted(Context context, int[] appWidgetIds)` Called in response to the `ACTION_APPWIDGET_DELETED` broadcast when one or more AppWidget instances have been deleted. Override this method to implement your own AppWidget functionality.
`void`	`onDisabled(Context context)` Called in response to the `ACTION_APPWIDGET_DISABLED` broadcast, which is sent when the last AppWidget instance for this provider is deleted. Override this method to implement your own AppWidget functionality.
`void`	`onEnabled(Context context)` Called in response to the `ACTION_APPWIDGET_ENABLED` broadcast when the a AppWidget for this provider is instantiated. Override this method to implement your own AppWidget functionality.
`void`	`onReceive(Context context, Intent intent)` Implements `onReceive(Context, Intent)` to dispatch calls to the various other methods on AppWidgetProvider.
`void`	`onRestored(Context context, int[] oldWidgetIds, int[] newWidgetIds)` Called in response to the `ACTION_APPWIDGET_RESTORED` broadcast when instances of this AppWidget provider have been restored from backup. If your provider maintains any persistent data about its widget instances, override this method to remap the old AppWidgetIds to the new values and update any other app state that may be relevant. This callback will be followed immediately by a call to `onUpdate(Context, AppWidgetManager, int[])` so your provider can immediately generate new RemoteViews suitable for its newly-restored set of instances.
`void`	`onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds)` Called in response to the `ACTION_APPWIDGET_UPDATE` and `ACTION_APPWIDGET_RESTORED` broadcasts when this AppWidget provider is being asked to provide `RemoteViews` for a set of AppWidgets. Override this method to implement your own AppWidget functionality.

Inherited methods

From class


  
    android.content.BroadcastReceiver

`final void`	`abortBroadcast()` Sets the flag indicating that this receiver should abort the current broadcast; only works with broadcasts sent through `Context.sendOrderedBroadcast`.
`final void`	`clearAbortBroadcast()` Clears the flag indicating that this receiver should abort the current broadcast.
`final boolean`	`getAbortBroadcast()` Returns the flag indicating whether or not this receiver should abort the current broadcast.
`final boolean`	`getDebugUnregister()` Return the last value given to `setDebugUnregister(boolean)`.
`final int`	`getResultCode()` Retrieve the current result code, as set by the previous receiver.
`final String`	`getResultData()` Retrieve the current result data, as set by the previous receiver.
`final Bundle`	`getResultExtras(boolean makeMap)` Retrieve the current result extra data, as set by the previous receiver.
`final BroadcastReceiver.PendingResult`	`goAsync()` This can be called by an application in `onReceive(Context, Intent)` to allow it to keep the broadcast active after returning from that function.
`final boolean`	`isInitialStickyBroadcast()` Returns true if the receiver is currently processing the initial value of a sticky broadcast -- that is, the value that was last broadcast and is currently held in the sticky cache, so this is not directly the result of a broadcast right now.
`final boolean`	`isOrderedBroadcast()` Returns true if the receiver is currently processing an ordered broadcast.
`abstract void`	`onReceive(Context context, Intent intent)` This method is called when the BroadcastReceiver is receiving an Intent broadcast.
`IBinder`	`peekService(Context myContext, Intent service)` Provide a binder to an already-running service.
`final void`	`setDebugUnregister(boolean debug)` Control inclusion of debugging help for mismatched calls to `Context.registerReceiver()`.
`final void`	`setOrderedHint(boolean isOrdered)` For internal use, sets the hint about whether this BroadcastReceiver is running in ordered mode.
`final void`	`setResult(int code, String data, Bundle extras)` Change all of the result data returned from this broadcasts; only works with broadcasts sent through `Context.sendOrderedBroadcast`.
`final void`	`setResultCode(int code)` Change the current result code of this broadcast; only works with broadcasts sent through `Context.sendOrderedBroadcast`.
`final void`	`setResultData(String data)` Change the current result data of this broadcast; only works with broadcasts sent through `Context.sendOrderedBroadcast`.
`final void`	`setResultExtras(Bundle extras)` Change the current result extras of this broadcast; only works with broadcasts sent through `Context.sendOrderedBroadcast`.

From class


  
    java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long millis, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long millis)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void`	`wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
