android - 使用 bindService 使 android 服务保持 Activity 状态

Question

我使用 bindService 方法启动服务。

但是当我点击 android 模拟器上的后退按钮时，我的服务被破坏了。

如何让服务在整个应用程序中保持 Activity 状态(我必须使用 bindService 与 Activity 进行通信)？

谢谢

更新这是错误日志

如果您使用 BIND_AUTO_CREATE 标志，那么您的服务将在 Activity 关闭时被销毁。您应该在 bindService() 之前使用 startService() 来防止这种情况
