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() {

        @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)) {

Because nobody mentioned it: You can't register receivers for screen on/off actions in the manifest. These ones only work when registered programmatically. – JacksOnF1re May 24 '16 at 12:32
it is possible to add multiple actions to one intent filter – Jacques Giraudel Nov 23 '17 at 14:01

If you want this receiver to be called by the system, you would need to export it. You set exported = "false", change this to true or remove exported entirely and this will start working. Normally this would be insecure, but as both SCREEN_ON and SCREEN_OFF are protected-broadcasts, and you verify the actions, only more trusted system code can send them too you, so it's pretty safe.

Sadly this wont work in this case as the intents broadcast have the following flags: Intent.FLAG_RECEIVER_REGISTERED_ONLY | Intent.FLAG_RECEIVER_FOREGROUND

Can you try with getting battery value:

public class Broadcast 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) {
            //Get battery percentage
            int batterylevel = intent.getIntExtra("level", 0);    
            //get progressbar
            ProgressBar myprogressbar = (ProgressBar) findViewById(R.id.progressbar);
            myprogressbar.setProgress(batterylevel);
            TextView tv = (TextView) findViewById(R.id.textfield);
            //Set TextView with text
            tv.setText("Battery Level: " + Integer.toString(batterylevel) + "%");
        }
    });

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_broadcast);   
        registerReceiver(mybroadcast, new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
    }
}

yaa it is working, bt i want that it is work after closing my app bcoz I m making lock screen, so u have any idea for that ? — user2290872, Apr 23 '13 at 05:46
