Bluetooth Headphone Button Triggering in Android studio, SDK level Min API 15 and Max API 28

Question

I need to detect the bluetooth HeadPhone device button click in my application. I followed many stackoverflow links, but doesn't seem to work for me.

Actual Working, When Headphone Button Clicked, Text apper in application "Button Pressed" or any other else

In this link I have tried, API 28 but its not Working Registering a headset button click with BroadcastReceiver in Android

No Error and No Output

public class RemoteControlReceiver extends BroadcastReceiver {

public RemoteControlReceiver(){
    super();
}

@Override
public void onReceive(Context context, Intent intent) {
    String intentAction = intent.getAction();
    Log.i ("TAG", intentAction.toString() + " happended");
    if (!Intent.ACTION_MEDIA_BUTTON.equals(intentAction)) {
        Log.i ("TAG", "no media button information");
        return;
    }
    KeyEvent event = (KeyEvent)intent.getParcelableExtra(Intent.EXTRA_KEY_EVENT);
    if (event == null) {
        Log.i ("TAG", "no keypress");
        return;
    }

}

MainActivity

    IntentFilter filter = new IntentFilter(Intent.ACTION_MEDIA_BUTTON);
    RemoteControlReceiver r = new RemoteControlReceiver();
    registerReceiver(r, filter);
