I am Facing a problem and problem is I started service in activity, I used the below method in service class but its not working. 

public boolean onKeyDown(int keyevent, keyEvent event) {
    if ((keyevent == KeyEvent.KEYCODE_VOLUME_DOWN)) {

        return true;
    }
    return onKeyDown(keyevent,event);

}

Shall I override keyevents in service class?

No, because there is no onKeyDown() method in the Service class.

  • I am trying to open flash light in keyevent_volume up which is called in service. Is there any other possiblities to open flash light app running in background. – Ramakrishna Apr 17 '15 at 14:32
  • @Ramakrishna: Bear in mind that not all Android devices have volume keys. There are some keys (and volume *might* be one of them) that trigger broadcasts -- take a look at the various broadcast actions defined on `Intent`. – CommonsWare Apr 17 '15 at 14:37
