Activity closes when service is stopped The code which i am using to start service is

Intent intent2 = new Intent(getApplicationContext(), TService.class);
startService(intent2);

and the code to stop service is 

 Intent intent2 = new Intent(getApplicationContext(), TService.class);
stopService(intent2);

i tried an alternative to use bind service but it showed the same behavior by closing the activity

code to start bind service was 

Intent intent2 = new Intent(getApplicationContext(), TService.class);
bindService(intent2, mServerConn, Context.BIND_AUTO_CREATE);
startService(intent2);

& code to stop bind service was 

stopService(new Intent(getApplicationContext(), TService.class));
unbindService(mServerConn);

My service TService.class

public class TService extends Service {



    @Override
    public IBinder onBind(Intent arg0) {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public void onDestroy() {
        Log.d("service", "destroy");

        super.onDestroy();
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {

        Log.d("TAG", "service started");
        context = getApplicationContext();
        return START_NOT_STICKY;
    }
}

My Activity MyActivity.java

public class MyActivity extends Activity{

    Button start,stop;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        start=(Button) findViewById(R.id.start);
        stop=(Button) findViewById(R.id.stop);



        final ServiceConnection mServerConn = new ServiceConnection() {
               @Override
                public void onServiceDisconnected(ComponentName name) {
                    Log.d("LOG_TAG", "onServiceDisconnected");
                }

                @Override
                public void onServiceConnected(ComponentName name, IBinder service) {
                    // TODO Auto-generated method stub
                     Log.d("LOG_TAG", "onServiceConnected");
                }
            };


        start.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub

                Intent intent2 = new Intent(getApplicationContext(), TService.class);
                intent2.putExtra("value", "1");
                startService(intent2);

            }
        });

        stop.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub


                Intent intent2 = new Intent(getApplicationContext(), TService.class);
                intent2.putExtra("value", "2");
                stopService(intent2);


            }
        });


    }



    private int getClicks() {
        clickCount++;
        return clickCount % 2 == 0 ? R.drawable.start : R.drawable.stop;
    }

    private boolean isMyServiceRunning() {
        ActivityManager manager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
        for (RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) {
            if (TService.class.getName().equals(service.service.getClassName())) {
                return true;
            }
        }
        return false;
    }



    @Override
    protected void onPause() {

    }


}

I am really stuck on it ,any suggestion or solution will be accepted Thanks in advance

startService(intent2)从您的代码中删除以启动绑定服务。通过调用绑定服务bindService(intent2, mServerConn, Context.BIND_AUTO_CREATE)无需调用startService(intent2)。并且取消绑定服务只需使用unbindService(mServerConn)

您需要在调用 stopService 之前调用 unbindService。我认为这就是原因。如果服务处于绑定状态，则除非未绑定，否则无法停止，这可能是您的活动关闭的原因。

这是你的问题：

@Override
protected void onPause() {

}

你已经被覆盖onPause()并且你**没有调用 super.onPause() inside it**. This will cause your app to crash whenonPause()` 被调用。

你说没有堆栈跟踪，但这是不正确的。您可能正在过滤 logcat 并错过了它。确保您没有过滤 logcat，您将在 logcat 中看到错误。
