notifyAppWidgetViewDataChanged

open fun notifyAppWidgetViewDataChanged(
    appWidgetId: Int, 
    viewId: Int
): Unit

Deprecated: The corresponding API RemoteViews.setRemoteAdapter(int, Intent) associated with this method has been deprecated. Moving forward please use RemoteViews.setRemoteAdapter(int, android.widget.RemoteViews.RemoteCollectionItems) instead to set android.widget.RemoteViews.RemoteCollectionItems for the remote adapter and update the widget views by calling updateAppWidget(int[],android.widget.RemoteViews), updateAppWidget(int,android.widget.RemoteViews), updateAppWidget(android.content.ComponentName,android.widget.RemoteViews), partiallyUpdateAppWidget(int[],android.widget.RemoteViews), or partiallyUpdateAppWidget(int,android.widget.RemoteViews), whichever applicable.

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

notifyAppWidgetViewDataChanged

open fun notifyAppWidgetViewDataChanged(
    appWidgetIds: IntArray!, 
    viewId: Int
): Unit

Deprecated: The corresponding API RemoteViews.setRemoteAdapter(int, Intent) associated with this method has been deprecated. Moving forward please use RemoteViews.setRemoteAdapter(int, android.widget.RemoteViews.RemoteCollectionItems) instead to set android.widget.RemoteViews.RemoteCollectionItems for the remote adapter and update the widget views by calling updateAppWidget(int[],android.widget.RemoteViews), updateAppWidget(int,android.widget.RemoteViews), updateAppWidget(android.content.ComponentName,android.widget.RemoteViews), partiallyUpdateAppWidget(int[],android.widget.RemoteViews), or partiallyUpdateAppWidget(int,android.widget.RemoteViews), whichever applicable.

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

partiallyUpdateAppWidget

open fun partiallyUpdateAppWidget(
    appWidgetId: Int, 
    views: RemoteViews!
): Unit

Perform an incremental update or command on the widget specified by appWidgetId.

This update differs from updateAppWidget(int,android.widget.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 RemoteViews.showNext(int), RemoteViews.showPrevious(int), RemoteViews.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[],android.widget.RemoteViews).

partiallyUpdateAppWidget

open fun partiallyUpdateAppWidget(
    appWidgetIds: IntArray!, 
    views: RemoteViews!
): Unit

Perform an incremental update or command on the widget(s) specified by appWidgetIds.

This update differs from updateAppWidget(int[],android.widget.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 RemoteViews.showNext(int), RemoteViews.showPrevious(int), RemoteViews.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[],android.widget.RemoteViews).

removeWidgetPreview

open fun removeWidgetPreview(
    provider: ComponentName, 
    widgetCategories: Int
): Unit

Remove this provider's preview for the specified widget categories. If the provider does not have a preview for the specified widget category, this is a no-op.

requestPinAppWidget

open fun requestPinAppWidget(
    provider: ComponentName, 
    extras: Bundle?, 
    successCallback: PendingIntent?
): Boolean

Request to pin an app widget on the current launcher. It's up to the launcher to accept this request (optionally showing a user confirmation). If the request is accepted, the caller will get a confirmation with extra EXTRA_APPWIDGET_ID.

When a request is denied by the user, the caller app will not get any response.

Only apps with a foreground activity or a foreground service can call it. Otherwise it'll throw IllegalStateException.

It's up to the launcher how to handle previous pending requests when the same package calls this API multiple times in a row. It may ignore the previous requests, for example.

Launcher will not show the configuration activity associated with the provider in this case. The app could either show the configuration activity as a response to the callback, or show if before calling the API (various configurations can be encapsulated in successCallback to avoid persisting them before the widgetId is known).

setWidgetPreview

open fun setWidgetPreview(
    provider: ComponentName, 
    widgetCategories: Int, 
    preview: RemoteViews
): Boolean

Set a preview for this widget. This preview will be used instead of the provider's previewLayout or previewImage for previewing the widget in the widget picker and pin app widget flow.

updateAppWidget

open fun updateAppWidget(
    provider: ComponentName!, 
    views: RemoteViews!
): Unit

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

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.

updateAppWidget

open fun updateAppWidget(
    appWidgetId: Int, 
    views: RemoteViews!
): Unit

Set the RemoteViews to use for the specified appWidgetId.

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,android.widget.RemoteViews).

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.

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.

updateAppWidget

open fun updateAppWidget(
    appWidgetIds: IntArray!, 
    views: RemoteViews!
): Unit

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[],android.widget.RemoteViews).

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.

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.

updateAppWidgetOptions

open fun updateAppWidgetOptions(
    appWidgetId: Int, 
    options: Bundle!
): Unit

Update the extras for 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.

The new options are merged into existing options using android.os.Bundle#putAll semantics.

updateAppWidgetProviderInfo

open fun updateAppWidgetProviderInfo(
    provider: ComponentName!, 
    metaDataKey: String?
): Unit

Updates the info for the supplied AppWidget provider. Apps can use this to change the default behavior of the widget based on the state of the app (for e.g., if the user is logged in or not). Calling this API completely replaces the previous definition.

The manifest entry of the provider should contain an additional meta-data tag similar to META_DATA_APPWIDGET_PROVIDER which should point to any alternative definitions for the provider.

This is persisted across device reboots and app updates. If this meta-data key is not present in the manifest entry, the info reverts to default.
