I have just started my app it does not have a gcm id so how can it recieve a message as in my logcat the last 2 line suggest and also my code for getting id is when i move to my login page. The app crashes the first time i start it and then when i start it again it runs smoothly without the above exception.
This looks like a known problem with a very old version of the GCM library. I would recommend updating to the latest version, as detailed here: https://developers.google.com/cloud-messaging/android/client
