Inner Broadcast receiver does not work?

I create an inner receiver InnerReceiver

  public class MainActi开发者_如何学运维vity extends Activity{
  ...

       class InnerReceiver extends BroadcastReceiver {
          @Override
          public void onReceive(Context context, Intent intent) {
             Log.v("InnerReceiver", "onReceive");
          }
       }

 ...
 }

The receiver is called as following:

   AlarmManager mgr=(AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
   PendingIntent pi=PendingIntent.getBroadcast(context, 0, new Intent(context,MainActivity.InnerReceiver.class), 0);

   mgr.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,
                SystemClock.elapsedRealtime()+1000,
                10000,
                pi);

The inner class is declared as:

However, the inner receiver is never called! Is anything wrong ? Thanks.

You need to register it in the <receiver> tag in your AndroidManifest.xml or dynamically by calling registerReceiver().

It may need to be declared public, rather than package-private as you have it. See more about Java access control here.

You will also need to broadcast something for it to receive, such as by calling sendBroadcast().
