Hey try using dynamic calling of broadcast,I tried this it will surly work...

public class MainActivity extends Activity {
     //Create broadcast object
       BroadcastReceiver mybroadcast = new BroadcastReceiver() {

        //When Event is published, onReceive method is called
        @Override
        public void onReceive(Context context, Intent intent) {
            // TODO Auto-generated method stub
                Log.i("[BroadcastReceiver]", "MyReceiver");

                if(intent.getAction().equals(Intent.ACTION_SCREEN_ON)){
                    Log.i("[BroadcastReceiver]", "Screen ON");
                }
                else if(intent.getAction().equals(Intent.ACTION_SCREEN_OFF)){
                    Log.i("[BroadcastReceiver]", "Screen OFF");
                }

        }
    };

     @Override
       public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.activity_main);

       registerReceiver(mybroadcast, new IntentFilter(Intent.ACTION_SCREEN_ON));
       registerReceiver(mybroadcast, new IntentFilter(Intent.ACTION_SCREEN_OFF));
     }
    }
