Music service is started but song is not playing

Question

I had created music player service which stop automatically on back pressed. I want to set it continuously until songs are available or user manually close from notification window. Any help appreciated.

Here below i put some code which i had created from reference

private MediaPlayer player;
    private final IBinder musicBind = new MusicBinder();
    public void onCreate(){
        super.onCreate();
        player = new MediaPlayer();
        initMusicPlayer();
    }

    public void initMusicPlayer(){
        //set player properties
        player.setWakeMode(getApplicationContext(), 
                PowerManager.PARTIAL_WAKE_LOCK);
        player.setAudioStreamType(AudioManager.STREAM_MUSIC);
        //set listeners
        player.setOnPreparedListener(this);
        player.setOnCompletionListener(this);
        player.setOnErrorListener(this);
    }

    public class MusicBinder extends Binder {
        MusicService getService() { 
            return MusicService.this;
        }
    }

    //activity will bind to service
    @Override
    public IBinder onBind(Intent intent) {
        return musicBind;
    }

    //release resources when unbind
    @Override
    public boolean onUnbind(Intent intent){
        //player.stop();
        //player.release();
        return false;
    }
@Override
    public void onDestroy() {
        //stopForeground(true);
    }

this code is used in activity to bind service bindService(playIntent, musicConnection, Context.BIND_AUTO_CREATE); startService(playIntent);

From above code my service is started but i'm not able to play song directly i had to click on play button

public void playSong() {
        player.reset();
        try {
        sendName_image();
        player.setDataSource(URI object);
        player.prepareAsync();

        } catch (Exception e) {
        }

    }

Above method is called on button click

`catch (Exception e) { } ` is the problem firstly. You will never know if something goes wrong since you just hide the exception. `e.printStackTrace()` it at least. — Vladyslav Matviienko, May 30 '17 at 09:02
dude if there is any error then player will be stop or not ? — rk android, May 30 '17 at 09:16
`} catch (Exception e) {}` => pro java code. Use this in production environnements and in critical systems for the best results. — 2Dee, May 30 '17 at 09:38
no, since you **ignore the exception**. As I said, at least add the `e.printStackTrace()` oinside the c`catch` block, so you at least see in logs that the exception happens. — Vladyslav Matviienko, May 30 '17 at 09:47
@2Dee, I don't think that asker is proficient in programming enough to understand your sarcasm. I'm afraid that your comment even can harm if he thinks that it is not a sarcasm. — Vladyslav Matviienko, May 30 '17 at 09:48
@VladMatvienko i put catch block with printStackTrace(); but no any error found — rk android, May 30 '17 at 10:13
