I am using GCM for push notifications for my project, but am stuck at acquiring wake lock.
Log message:

GCMIntentService----> This class file is inside com.thinkappz.advancedtictactoe package, but my R.java file is generated inside example.pro. I don't know why.

I also tried <service android:name="example.pro.GCMIntentService" /> But then it is giving me an error while registering, saying that it can't instantiate service.
You are using the com.google.android.gcm.GCMBroadcastReceiver broadcast receiver from the Google GCM client library. This class expects the intent service to be in the main package of your app (example.pro) but your intent service is in a different package - com.thinkappz.advancedtictactoe. That's why the receiver can't find the service.
You should either move the GCMIntentService to the main package of your app, or override GCMBroadcastReceiver.
