AppWidgetProvider

open class AppWidgetProvider : BroadcastReceiver
kotlin.Any
   ↳ 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, onDeleted, onEnabled or onDisabled methods to implement your own AppWidget functionality.

Parameters
context Context!: The Context in which this receiver is running.
appWidgetIds IntArray!: The appWidgetIds that have been deleted from their host.

onDisabled

Added in API level 3
open fun onDisabled(context: Context!): Unit

Called in response to the AppWidgetManager#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. {@more}

Parameters
context Context!: The Context in which this receiver is running.

onEnabled

Added in API level 3
open fun onEnabled(context: Context!): Unit

Called in response to the AppWidgetManager#ACTION_APPWIDGET_ENABLED broadcast when the a AppWidget for this provider is instantiated. Override this method to implement your own AppWidget functionality. {@more} When the last AppWidget for this provider is deleted, AppWidgetManager#ACTION_APPWIDGET_DISABLED is sent by the AppWidget manager, and onDisabled is called. If after that, an AppWidget for this provider is created again, onEnabled() will be called again.

Parameters
context Context!: The Context in which this receiver is running.

onReceive

Added in API level 3
open fun onReceive(
    context: Context!,
    intent: Intent!
): Unit

Implements BroadcastReceiver#onReceive to dispatch calls to the various other methods on AppWidgetProvider.

Parameters
context Context!: The Context in which the receiver is running.
intent Intent!: The Intent being received.

onRestored

Added in API level 21
open fun onRestored(
    context: Context!,
    oldWidgetIds: IntArray!,
    newWidgetIds: IntArray!
): Unit

Called in response to the AppWidgetManager#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 so your provider can immediately generate new RemoteViews suitable for its newly-restored set of instances.

In addition, you should set AppWidgetManager#OPTION_APPWIDGET_RESTORE_COMPLETED to true indicate if a widget has been restored successfully from the provider's side. {@more}

Parameters
context Context!:
oldWidgetIds IntArray!:
newWidgetIds IntArray!:
