I tried to implement GCM Demo Application’s code to my application, so here is the code.

GCMRegistrar.checkDevice(this);
GCMRegistrar.checkManifest(this);

registerReceiver(mHandleMessageReceiver, new IntentFilter(DISPLAY_MESSAGE_ACTION));
final String regId = GCMRegistrar.getRegistrationId(this);

if (regId.equals("")) {
    // Automatically registers application on
    // startup.
    GCMRegistrar.register(this, SENDER_ID);
} else {
    Log.v(TAG, "Already registered");
    // Device is already registered on GCM, needs to
    // check if it is
    // registered on our server as well.
    if (!GCMRegistrar.isRegisteredOnServer(this)) {
        // Try to register again, but not in the UI
        // thread.
        // It's also necessary to cancel the thread
        // onDestroy(),
        // hence the use of AsyncTask instead of a
        // raw thread.
        final Context context = this;
        mRegisterTask = new AsyncTask<Void, Void, Void>() {
            mRegisterTask.execute(null, null, null);
        }
    }
}

I found my problem, its all of my fault and sillyness.

I was added GCMRegistrar.unregister () code to Evaluations; so every step on debug cause to reevaluate this code and call unregister.

I don’t want to delete it, may be there is someone like me 😉
