APAR status

• Closed as program error.

Error description

• When an application attempts to connects to a
  Worklight/MobileFirst server but does not have a connection to
  the internet,
  the application crashes with the following exception
  
  E/ActivityThread(9222): Activity
  [activity name] has leaked IntentReceiver
  com.worklight.androidgap.plugin.Push$4@42bfe8a8 that was
  originally registered here. Are you missing a call to
  unregisterReceiver()?
  
  The issue lies in Push Hybrid not providing the senderIds
  correctly to the GCM service when there is a retry to connect
  to GCM server after the first SERVICE_NOT_AVAILABLE error.

  * PROBLEM DESCRIPTION:                                         *
  * The issue occurs with the retry logic code which needs to    *
  * keep attempting to connect to GCM server with a exponential  *
  * backoff. The retry logic only kicks in after the first       *
  * failure to connect to GCM.                                   *
  ****************************************************************
  * RECOMMENDATION:                                              *
  * -                                                            *

Problem conclusion

• The fix ensures that the retry logic is correctly used from the
  gcm client. There will be a exponential backoff when attempting
  to connect to Google Cloud messaging server.
