GCM android Error receiving broadcast Intent { act=DISPLAY.MESSAGE flg=0x10 (has extras)

I have troubles when I start the app and register device in Gcm

Any idea how to fix it?

The rest is working fine, I receive the notification and correctly. 

private final BroadcastReceiver mHandleMessageReceiver = new BroadcastReceiver() {

        @Override
        public void onReceive(Context context, Intent intent) {

            Log.v("MESSAGE", intent.getExtras().getString("message") );
            String newMessage = intent.getExtras().getString("message");
            // Waking up mobile if it is sleeping
            aController.acquireWakeLock(getApplicationContext());       
            Toast.makeText(getApplicationContext(), "Got Message: " + newMessage, Toast.LENGTH_LONG).show();
            // Releasing wake lock
            aController.releaseWakeLock();
        }
    };

Error

Try 

Log.v("MESSAGE", intent.getExtras().getString("price"));
String newMessage = intent.getExtras().getString("price");

your code for extra is returning null, 

String newMessage = intent.getExtras().getString("message");

use try catch, and make sure you have extra to be received from there!
