How can I register the device id for push notifications

[cgsneem...@gmail.com]

II have dealt with the following lines, but I do not get the registry of the devide, I am working with netbeans

Hashtable meta = new Hashtable();

                meta.put(com.codename1.push.Push.GOOGLE_PUSH_KEY, GCM_SENDER_ID);        

                Display.getInstance().registerPush(meta, true);

In which device type are you having a problem?
Notice that push doesn't really work in the simulator.

Did you implement PushCallback in your main class?
Are any of the push callback methods invoked?
