How to start a service in Oncreate without button Onclick ,but it should be stopped using button

Question

I am trying to play music continuously in background without any button click,it should play on launching activity,and again it can be stopped by stop button.But it is not stopping as it is placed in Oncreate() ,what can be the solution for this. Please anyone tell me how to stopservice.Thankyou in advance.

 @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    start = findViewById(R.id.startbutton);
    stop = findViewById(R.id.stopbutton);


    Intent i = new Intent(this, Service.class);
    this.startService(i);
    stop.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent i = new Intent(view.getContext(), Service.class);
            stopService(i);
            Toast.makeText(MainActivity.this, "stop service called", Toast.LENGTH_SHORT).show();
        }
    });
    start.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent i = new Intent(view.getContext(), Service.class);
            startService(i);
        }
    });

}

Below is my Service code

private MediaPlayer player;
public Service() {
    super();
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
  player= MediaPlayer.create(this,
          Settings.System.DEFAULT_RINGTONE_URI);
  player.setLooping(true);
  player.start();
  return START_STICKY;
}

@Override
public void onDestroy() {
    super.onDestroy();
    player.stop();
}

@Nullable
@Override
public IBinder onBind(Intent intent) {
    return null;
}

}

can you update your question with `ESS_Service` where you start and stop the music? — Sagar, Jun 29 '18 at 06:53

Please Add this override method and call what ever service you need.

@Override
 public void onResume() {
  super.onResume();
  startService(new Intent(YourActivity.this, ServiceName.class));
}

Service is getting called,but it is not stopping by clicklistener when I close the app and reopen. – user9396014 Jun 29 '18 at 09:28
in onDestroy you can stopservice, and also in clicklistener of stop view using stopSelf(). – Harish Reddy Jun 29 '18 at 13:46

I have thought of two solutions :

1:Just don't use clicklistener . Immediately start the service when launching the activity

2: If you want to use start button , call start.performClick()

To stop the player on home screen use this method

    @Override
public void onPause() {
    super.onPause();
    player.stop();
}

Yeah I am starting service immediately without clicklistener,but how can I stop service on clicklistener,that is my question. – user9396014 Jun 29 '18 at 09:08
write the `stop.setOnClickListener` code outside onCreate and try – Kevin Kurien Jun 29 '18 at 09:25
If still not working try writing the code in `onStart` or `onResume` – Kevin Kurien Jun 29 '18 at 09:31
I tried both ,still stop service is not working after closing and reopening app – user9396014 Jun 29 '18 at 09:43
Have you declared the service in AndroidManifest.xml. `` – Kevin Kurien Jun 29 '18 at 10:51
you are calling `player.stop` in `onDestroy` which is only called when you remove the app from the recent apps stack from your mobile – Kevin Kurien Jun 29 '18 at 10:53
I have added a code in my answer try it and tell me what happens – Kevin Kurien Jun 29 '18 at 11:00
There is no onPause method in Android service lifecycle.So I am not able to add it. – user9396014 Jun 29 '18 at 11:19
Try to add onPause it in MainActivity class – Kevin Kurien Jun 29 '18 at 11:24
I have tried it in onPause and in all lifecycle methods in MainActivity class. – user9396014 Jun 29 '18 at 11:34

I am returning START_NOT_STICKY in onStartCommand method in Service class instead of START_STICKY.Because of that my service was restarting every time when I reopen the app.So now I am able to stop service and my problem got solved.

@Override
protected void onPause() {
    super.onPause();
    this.stopService(i);
}

@Override
protected void onResume() {
    super.onResume();
    this.startService(i);
}

@Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    start = findViewById(R.id.startbutton);
    stop = findViewById(R.id.stopbutton);


     i = new Intent(this, MusicService.class);
    this.startService(i);
    stop.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            if(i!=null) {
                stopService(i);
                Toast.makeText(MainActivity.this, "stop service called", Toast.LENGTH_SHORT).show();
            }
            }
    });
}

Make intent a class variable and override onPause and onResume. That should do the trick. As mentioned by Harish Reddy. — saiyan, Jan 21 '22 at 06:11
