Get the list of appWidgetIds that have been bound to the given AppWidget provider.

Get the available info about the AppWidget.

Get the extras associated with a given widget instance. The extras can be used to embed additional information about this widget to be accessed by the associated widget's AppWidgetProvider.

Return a list of the AppWidget providers that are currently installed.

Notifies the specified collection view in all the specified AppWidget instances to invalidate their data.

Notifies the specified collection view in the specified AppWidget instance to invalidate its data.

Perform an incremental update or command on the widget specified by appWidgetId. This update differs from updateAppWidget(int, RemoteViews) in that the RemoteViews object which is passed is understood to be an incomplete representation of the widget, and hence is not cached by the AppWidgetService. Note that because these updates are not cached, any state that they modify that is not restored by restoreInstanceState will not persist in the case that the widgets are restored using the cached version in AppWidgetService. Use with showNext(int), showPrevious(int), setScrollPosition(int, int) and similar commands.

It is okay to call this method both inside an ACTION_APPWIDGET_UPDATE broadcast, and outside of the handler. This method will only work when called from the uid that owns the AppWidget provider.

This method will be ignored if a widget has not received a full update via updateAppWidget(int[], RemoteViews).

Perform an incremental update or command on the widget(s) specified by appWidgetIds. This update differs from updateAppWidget(int[], RemoteViews) in that the RemoteViews object which is passed is understood to be an incomplete representation of the widget, and hence does not replace the cached representation of the widget. As of API level 17, the new properties set within the views objects will be appended to the cached representation of the widget, and hence will persist. Use with showNext(int), showPrevious(int), setScrollPosition(int, int) and similar commands.

Set the RemoteViews to use for the specified appWidgetIds. Note that the RemoteViews parameter will be cached by the AppWidgetService, and hence should contain a complete representation of the widget. For performing partial widget updates, see partiallyUpdateAppWidget(int[], RemoteViews).

The total Bitmap memory used by the RemoteViews object cannot exceed that required to fill the screen 1.5 times, ie. (screen width x screen height x 4 x 1.5) bytes.

Set the RemoteViews to use for all AppWidget instances for the supplied AppWidget provider.
