Subject: [PATCH 1/2] This commit will let us know if the message is sent or
 not for android. I used android "BroadcastReceiver" to check if the SMS is
 sent or not. The broadcast receiver will handle all types of message failures
 in android. - No credit - No service for SMS - Null PDU - Airplane mode
 turned on
