You need to add this in your code.

您需要在代码中添加它。

@Override
protected void onDestroy() {
    super.onDestroy();
    unbindService(m_serviceConnection);
    Toast.makeText(MainActivity.this, "Service Un-Binded", Toast.LENGTH_LONG).show();
};

Another good practice to do this could be adding a flag to know when the service was added.

另一个很好的做法是添加一个标志来了解何时添加服务。

private boolean m_serviceBound = false;
private ServiceConnection m_serviceConnection = new ServiceConnection() 
{
    ...
};


@Override
protected void onCreate(Bundle savedInstanceState) 
{
    ...
    Intent intent = new Intent(this, CallNotifierService.class);
    bindService(intent, m_serviceConnection, Context.BIND_AUTO_CREATE);
    m_serviceBound = true;
    ...
}

@Override
protected void onDestroy() {
    ...
    if (m_serviceBound) {
        unbindService(m_serviceConnection);
        m_serviceBound = false;
    }
    ...
};

This is useful if you bind and unbind the service in different segments of the app's life cycle.

如果您在应用程序生命周期的不同阶段绑定和取消绑定服务，这将非常有用。

onStop()

停止（）

is another place where you can unbind a service in your activity.

是另一个您可以在您的活动中取消绑定服务的地方。

This approach is quite preferable when you want to interact with a service only when your Activity is in the foreground. See official Android Developer guide suggestion

当您只想在您的 Activity 在前台时与服务交互时，这种方法非常可取。查看官方 Android 开发者指南建议

Override
protected void onStop() {
   super.onStop();
   unbindService(m_serviceConnection);
};

In this case, prefered way to bind service is in the onStart()method of the Activity.

在这种情况下，绑定服务的首选方式是在onStart()Activity的方法中。
