Procesar varios eventos en un widget en Android

En la clase que extiende el WidgetProvider

public class ExampleProvider extends AppWidgetProvider {

// our actions for our buttons
public static String ACTION_WIDGET_REFRESH = "ActionReceiverRefresh";
public static String ACTION_WIDGET_SETTINGS = "ActionReceiverSettings";
public static String ACTION_WIDGET_ABOUT = "ActionReceiverAbout";


@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
    RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.main_layout);

    Intent active = new Intent(context, ExampleProvider.class);
    active.setAction(ACTION_WIDGET_REFRESH);
    PendingIntent actionPendingIntent = PendingIntent.getBroadcast(context, 0, active, 0);
    remoteViews.setOnClickPendingIntent(R.id.button_refresh, actionPendingIntent);

    active = new Intent(context, ExampleProvider.class);
    active.setAction(ACTION_WIDGET_SETTINGS);
    actionPendingIntent = PendingIntent.getBroadcast(context, 0, active, 0);
    remoteViews.setOnClickPendingIntent(R.id.button_settings, actionPendingIntent);

    active = new Intent(context, ExampleProvider.class);
    active.setAction(ACTION_WIDGET_ABOUT);
    actionPendingIntent = PendingIntent.getBroadcast(context, 0, active, 0);
    remoteViews.setOnClickPendingIntent(R.id.button_about, actionPendingIntent);

    appWidgetManager.updateAppWidget(appWidgetIds, remoteViews);
}

@Override
public void onReceive(Context context, Intent intent) {
    if (intent.getAction().equals(ACTION_WIDGET_REFRESH)) {
        Log.i("onReceive", ACTION_WIDGET_REFRESH);
    } else if (intent.getAction().equals(ACTION_WIDGET_SETTINGS)) {
        Log.i("onReceive", ACTION_WIDGET_SETTINGS);
    } else if (intent.getAction().equals(ACTION_WIDGET_ABOUT)) {
        Log.i("onReceive", ACTION_WIDGET_ABOUT);
    } else {
        super.onReceive(context, intent);
    }
}

En la definición de la aplicación se deben registrar las acciones (aunque a mí me funciona sin definirlas)

 <receiver android:name="ExampleProvider">
        <intent-filter>
            <action android:name="android.appwidget.action.APPWIDGET_UPDATE"/>
            <action android:name="org.divenvrsk.widgets.ExampleProvider.ACTION_WIDGET_REFRESH"/>
            <action android:name="org.divenvrsk.widgets.ExampleProvider.ACTION_WIDGET_SETTINGS"/>
            <action android:name="org.divenvrsk.widgets.ExampleProvider.ACTION_WIDGET_ABOUT"/>
        </intent-filter>
        <meta-data android:name="android.appwidget.provider" android:resource="@xml/widget_info"/>
    </receiver>
</application>
