android Notification doesnt trigger BroadcastReceiver's onReceive

Question

Is it possible to have a notification start a broadcast receiver?

I tried this code but it doesnt work.

Notification is created but when I click on it nothing happens.

NOTE: When I change the notificationIntent to point from MyBroadcastReceiver.class to an activity (like MainActivity.class) it works fine.

Notification creation:

    NotificationManager notificationManager = (NotificationManager) context.getSystemService(
        Context.NOTIFICATION_SERVICE);

    int notificationIconId = XXXXXX
    Notification notification = new Notification(
        notificationIconId,
        XXXXXX,
        System.currentTimeMillis()
    );

    CharSequence contentTitle = XXXXXXX
    CharSequence contentText = XXXXXX

    Intent notificationIntent = new Intent(context,MyBroadcastReceiver.class);
    PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);

    notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);
    notificationManager.notify(1,notification);

Here is the BroadcastReceiver

public static class MyBroadcastReceiver extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {
   /*
          */

 }
}

Inside AndroidManifest.xml

<receiver android:name=".MyBroadcastReceiver" />

From your code...

PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);

When creating a PendingIntent targetting a BroadcastReceiver , you have to use getBroadcast(...) and not getActivity(...) .

See PendingIntent.getBroadcast(Context context, int requestCode, Intent intent, int flags)

Also, don't create your Intent like this...

Intent notificationIntent = new Intent(context,MyBroadcastReceiver.class);

That is an explicit Intent which targets a specific class (used for starting a specific Activity class usually).

Instead create a 'broadcast' Intent with an 'action' such as...

Intent notificationIntent = new Intent(MyApp.ACTION_DO_SOMETHING);

You'll also need to specify a <intent-filter> section for the <receiver android:name=".MyBroadcastReceiver" /> section of your manifest.
