KeyCode, KeyEvent Not working

Question

How can i stop services which is running on background. Is there any way to do it using Back and home button press

I have tried to do it using key events but still it's not working. Here you can check my code below ...

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if ((keyCode == KeyEvent.KEYCODE_HOME)) {          
        stopBackgroundAudio();// background services 
        return true;
    }
    if ((keyCode == KeyEvent.KEYCODE_BACK)) {           
        stopBackgroundAudio();
        return true;
    }
    if ((keyCode == KeyEvent.KEYCODE_MENU)) {            
        stopBackgroundAudio();
        return true;
    }
     return super.onKeyDown(keyCode, event);

}

Help me with this or suggest me other option to stop service?

These key are handled by Android OS. But you can use it using reflection. See http://stackoverflow.com/a/31872330/3496570 — Zar E Ahmer, Aug 07 '15 at 07:51

Back and home don't use that API. THe back key comes in via the backButtonPressed function, which you can override. The home button doesn't come up ever- your app just gets pushed to the background.

Also, if you want the audio to stop when you're put int he background, just stop it in onPause.

This would not solve issue since onPause is also called while moving from one activity to another – TheMohanAhuja Mar 28 '14 at 07:56
True, but he didn't specify he needed that. – Gabe Sechan Mar 28 '14 at 07:58
Right my friend, but he clearly specified that he wants to stop service only on home press or back button. – TheMohanAhuja Mar 28 '14 at 08:00

@Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {

        switch(keyCode)
        {
        case KeyEvent.KEYCODE_HOME:
        stopBackgroundAudio();// background services 
            return true;
        case KeyEvent.KEYCODE_BACK:
         stopBackgroundAudio();
            return true;
        case KeyEvent.KEYCODE_MENU:
       stopBackgroundAudio();
            return true;


        }

       return super.onKeyDown(keyCode, event);
    }

i am not sure yours service is a bind or unbind service, if it is unbind service than it may be a problem and also if it is a bind service than have a proper implementation!!

hey use return super.onKeyDown(keyCode, event); in place of return false; answer is updated — Jitesh Upadhyay, Mar 28 '14 at 08:07
