android - 终止android服务后获取ANR

Question

我有一个使用 bindService() 方法启动本地服务的 Activity 。应用程序运行时一切正常，但是当我在 Activity 的 onDestroy() 中终止应用程序并与服务解除绑定(bind)时，几秒钟后我看到 logcat 中出现以下错误:

不太确定这里发生了什么，因为 Activity 和服务都已终止(onDestroy() 已在两者中执行)。我猜还有一个线程在某处运行？该服务确实会创建和使用 Android MediaPlayer。

Answer 1

我在服务终止后也收到了 ANR 消息。

我的问题是应用程序的主要 Activity 调用了两次“bindService()”——一次在“startService()”之前，一次之后。

删除对 bindService() 的调用都解决了问题。
