Android mobile first app stopped working after Bluemix moved to cflinuxfs2 stack
I have an android app based on the bluelist app for bluemix BMS service. it stopped working yesterday when the stack is moved to cflinuxfs2.
Today I checked my ios app on the same bluemix service, it is working. so I looked into the exception on Android, it is from MFPush, looks like a context is null. see the attached image for the line of code where the NPE is thrown.
The stacktrace is: java.lang.NullPointerException: Attempt to invoke virtual method 'android.content.Intent android.content.Context.registerReceiver(android.content.BroadcastReceiver, android.content.IntentFilter)' on a null object reference

Chances are the MFPPush SDK has not been initialized when you are attempting to call:
push.listen(notificationListener)
I suggest saving the push value:
push = MFPPush.getInstance()
Immediately after initialization or registration (whatever you feel is more appropriate) in the class.
That way you will have the appropriate initialized push instance when attempting to listen to a notification listener.
