service本地服务通信（无法查看状态）

Question

可以绑定服务与解绑，但是无法查看状态

也没有服务断开连接的提示

MainActivity的代码

public class MainActivity extends AppCompatActivity {
    MyService.MyBinder myBinder;
    //定义一个ServiceConnection对象
    private ServiceConnection connection = new ServiceConnection() {
        @Override
        public void onServiceConnected(ComponentName componentName, IBinder iBinder) {
            Log.v("MainActivity", "服务连接成功");
            myBinder = (MyService.MyBinder) iBinder;
        }
        @Override
        public void onServiceDisconnected(ComponentName componentName) {
            Log.v("MainActivity", "服务断开连接");
        }
    };
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
    public void onClick(View view) {
            switch (view.getId()) {
                case R.id.b1:
                    //绑定服务service
                    Intent intent = new Intent(this, MyService.class);
                    bindService(intent, connection, BIND_AUTO_CREATE);
                    break;
                case R.id.b2:
                    //解除绑定服务service
                    unbindService(connection);
                    break;
                case R.id.b3:
                    Toast.makeText(this, myBinder.getCount(), Toast.LENGTH_SHORT).show();
                    break;
                default:
                    break;
            }
        }
    }
