Android Update Widget From Broadcast Receiver

I have an widget and I must update the widget when action android.media.RINGER_MODE_CHANGED occurs. I have the folowing broadcast receiver: public void onReceive(Context context, I

Solution 1:

it seems that AppWidgetProvider extends BroadcastReceiver so here is my code :

public class ExampleAppWidgetProvider extends AppWidgetProvider {
    DateFormat df = new SimpleDateFormat("hh:mm:ss");

    public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
        //my update code here
    }

    @Override
    public void onReceive(Context context, Intent intent) {
        AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(context.getApplicationContext());
        ComponentName thisWidget = new ComponentName(context.getApplicationContext(), ExampleAppWidgetProvider.class);
        int[] appWidgetIds = appWidgetManager.getAppWidgetIds(thisWidget);
        if (appWidgetIds != null && appWidgetIds.length > 0) {
            onUpdate(context, appWidgetManager, appWidgetIds);
        }
    }
}

<receiver android:name=".ExampleAppWidgetProvider" android:label="demo widget">
    <intent-filter>
        <action android:name="android.appwidget.action.APPWIDGET_UPDATE"/>
    </intent-filter>
    <intent-filter>
        <action android:name="android.media.RINGER_MODE_CHANGED"/>
    </intent-filter>
    <meta-data android:name="android.appwidget.provider" android:resource="@xml/widget1_info"/>
</receiver>
