AppWidgetProvider Class

Definition

A convenience class to aid in implementing an AppWidget provider.

[Android.Runtime.Register("android/appwidget/AppWidgetProvider", DoNotGenerateAcw=true)]
public class AppWidgetProvider : Android.Content.BroadcastReceiver
[<Android.Runtime.Register("android/appwidget/AppWidgetProvider", DoNotGenerateAcw=true)>]
type AppWidgetProvider = class
    inherit BroadcastReceiver
Inheritance
AppWidgetProvider
Attributes

Remarks

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) 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.

Constructors

AppWidgetProvider()

Constructor to initialize AppWidgetProvider.

AppWidgetProvider(IntPtr, JniHandleOwnership)

A constructor used when creating managed representations of JNI objects; called by the runtime.

Properties

AbortBroadcast

Returns the flag indicating whether or not this receiver should abort the current broadcast.

(Inherited from BroadcastReceiver)
Class

Returns the runtime class of this Object.

(Inherited from Object)
DebugUnregister

Return the last value given to #setDebugUnregister. -or- Control inclusion of debugging help for mismatched calls to Context#registerReceiver(BroadcastReceiver, IntentFilter) Context.registerReceiver().

(Inherited from BroadcastReceiver)
Handle

The handle to the underlying Android instance.

(Inherited from Object)
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.

(Inherited from BroadcastReceiver)
IsOrderedBroadcast

Returns true if the receiver is currently processing an ordered broadcast.

(Inherited from BroadcastReceiver)
JniIdentityHashCode (Inherited from Object)
JniPeerMembers
PeerReference (Inherited from Object)
ResultCode

Retrieve the current result code, as set by the previous receiver. -or- Change the current result code of this broadcast; only works with broadcasts sent through Context#sendOrderedBroadcast(Intent, String) Context.sendOrderedBroadcast.

(Inherited from BroadcastReceiver)
ResultData

Retrieve the current result data, as set by the previous receiver. -or- Change the current result data of this broadcast; only works with broadcasts sent through Context#sendOrderedBroadcast(Intent, String) Context.sendOrderedBroadcast.

(Inherited from BroadcastReceiver)
SentFromPackage

Returns the package name of the app that initially sent this broadcast.

(Inherited from BroadcastReceiver)
SentFromUid

Returns the uid of the app that initially sent this broadcast.

(Inherited from BroadcastReceiver)

Equals(Object)

Indicates whether some other object is "equal to" this one.

(Inherited from Object)
GetHashCode()

Returns a hash code value for the object.

(Inherited from Object)
GetResultExtras(Boolean)

Retrieve the current result extra data, as set by the previous receiver.

(Inherited from BroadcastReceiver)
GoAsync()

This can be called by an application in #onReceive to allow it to keep the broadcast active after returning from that function.

(Inherited from BroadcastReceiver)
InvokeAbortBroadcast()

Sets the flag indicating that this receiver should abort the current broadcast; only works with broadcasts sent through Context#sendOrderedBroadcast(Intent, String) Context.sendOrderedBroadcast.

(Inherited from BroadcastReceiver)
JavaFinalize()

Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.

(Inherited from Object)
Notify()

Wakes up a single thread that is waiting on this object's monitor.

NotifyAll()

Wakes up all threads that are waiting on this object's monitor.

(Inherited from Object)
OnAppWidgetOptionsChanged(Context, AppWidgetManager, Int32, Bundle)
