Its throwing exception while calling GCM.register(this,SENDER_ID);
java.lang.UnsupportedOperationException: Device does not have package com.google.android.gsf
What is alternative option of GCM on Amazon devices?
回答1:
Kindle Fire don't have "Google Play Services" library installed, so GCM won't work. Try ADM instead.
回答2:
GCM have some limitation,
In android device must have google play store, second one is android device configure with google account (This limitation in some devices.).
You got error this because kindle dose not have this package which gcm needed.
