我有一个应用程序,它绑定了一个长时间运行的Service
。
我需要确保当用户从Activity
导航离开时,Service
停止。
因此,我实现了onStop()
方法来关闭服务:
以下是代码:
@Override
protected void onStop() {
super.onStop();
if(mService!=null)mService.stop();
stopService(new Intent(this, LocalService.class));
unbindService(mConnection);
stopService(intent);
}
这是我的LogCat:

感谢您的帮助!!!
onStop()
不是用来停止一个服务的,而是系统通知该服务正在被停止。 - S.D.onStop()
是在 Activity 中的,当用户从该 Activity 导航时,它会被调用,在那个onStop()
中,我需要停止和断开服务,调用stopService(new Intent(this, LocalService.class));
和unbindService(mConnection);
。 - Lisa AnnestartService()
,则需要调用stopService()
。如果您只是绑定到服务,则当所有客户端从中解除绑定时,服务将自动停止。 - S.D.
