Answer 1

您需要在代码中添加此内容。

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

Answer 2

另一种好的做法是添加一个标志，以了解何时添加了服务。

List<String> list = new ArrayList<String>();
list.add("A");
list.add("B");
list.add("C");
List<String> copyList = new ArrayList<String>(); 
Consumer<String> consumer = s->copyList.add(s);
list.stream().forEach(consumer);

如果您在应用程序生命周期的不同阶段中绑定和取消绑定服务，这将非常有用。

Answer 3

onStop（）

是您可以在活动中取消绑定服务的另一个位置。

当您想与仅当您的活动处于前台时才提供服务。 See official Android Developer guide suggestion

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

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

android.app.ServiceConnectionLeaked：Activity ... MainActivity泄露了ServiceConnection ... MainActivity $ 1 @ e794142最初绑定在这里
