Estou trabalhando em um widget Android. Esta é minha classe AppWidgetProvider:

public class MyWidgetProvider extends AppWidgetProvider {

public static String ACTION_CHARGE = "Charge";
public static String ACTION_BALANCE = "Balance";
public static String ACTION_SEND_BALANCE = "SendBalance";
public static String ACTION_CALL_ME = "CallMe";

@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
        int[] appWidgetIds) {

    // Get all ids
    ComponentName thisWidget = new ComponentName(context,
            MyWidgetProvider.class);
    int[] allWidgetIds = appWidgetManager.getAppWidgetIds(thisWidget);
    for (int widgetId : allWidgetIds) {

        RemoteViews remoteViews = new RemoteViews(context.getPackageName(),
                R.layout.widget_layout);

        // Register onClickListeners
        Intent intent = new Intent(context, MyWidgetProvider.class);
        intent.setAction(ACTION_CHARGE);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(context,
                0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
        remoteViews.setOnClickPendingIntent(R.id.ib_charge, pendingIntent);

        intent = new Intent(context, MyWidgetProvider.class);
        intent.setAction(ACTION_BALANCE);
        pendingIntent = PendingIntent.getBroadcast(context, 1, intent,
                PendingIntent.FLAG_UPDATE_CURRENT);
        remoteViews.setOnClickPendingIntent(R.id.ib_balance, pendingIntent);

        intent = new Intent(context, MyWidgetProvider.class);
        intent.setAction(ACTION_SEND_BALANCE);
        pendingIntent = PendingIntent.getBroadcast(context, 2, intent,
                PendingIntent.FLAG_UPDATE_CURRENT);
        remoteViews.setOnClickPendingIntent(R.id.ib_charge_send,
                pendingIntent);

        intent = new Intent(context, MyWidgetProvider.class);
        intent.setAction(ACTION_CALL_ME);
        pendingIntent = PendingIntent.getBroadcast(context, 3, intent,
                PendingIntent.FLAG_UPDATE_CURRENT);
        remoteViews.setOnClickPendingIntent(R.id.ib_call_me, pendingIntent);

        appWidgetManager.updateAppWidget(widgetId, remoteViews);
    }
}

@Override
public void onReceive(Context context, Intent intent) {
    if (intent.getAction().equals(ACTION_CHARGE)) {
        Log.d("onReceive", ACTION_CHARGE);
        context.startActivity(new Intent("android.intent.action.CALL", Uri
                .parse("tel:*789*1415" + Uri.encode("#"))));
    } else if (intent.getAction().equals(ACTION_BALANCE)) {
        Log.d("onReceive", ACTION_BALANCE);
    } else if (intent.getAction().equals(ACTION_SEND_BALANCE)) {
        Log.d("onReceive", ACTION_SEND_BALANCE);
    } else if (intent.getAction().equals(ACTION_CALL_ME)) {
        Log.d("onReceive", ACTION_CALL_ME);
    }

    super.onReceive(context, intent);
    Log.d("onReceive",
            "***********************************************************************");

}
}

ٌٌ Mas o método onReceive nunca é chamado. Onde está o problema?
