Solution 1:

Use Pending Intent

A pending intent is a token that you give to another application (e.g., notification manager, alarm manager or other 3rd party applications), which allows this other application to use the permissions of your application to execute a predefined piece of code.

To perform a broadcast via a pending intent, get a PendingIntent via the getBroadcast() method of the PendingIntent class. To perform an activity via a pending intent, you receive the activity via PendingIntent.getActivity().

Or

PendingIntent + Alarm Manager + Broadcast Receiver combination can work fine you have to register and unregistere broadcast receiver dynamically not in manifest. Like

publicvoidonResume()
  {
    IntentFilter filter = new IntentFilter();
    filter.addAction("android.provider.Telephony.SMS_RECEIVED");
    registerReceiver(mybroadcast, filter);  

  }

  publicvoidonPause()
  {
    unregisterReceiver(mybroadcast);
  }
