终止android服务后获得ANRs

android

我有一个使用bindService()方法启动本地服务的活动。当应用程序运行时,一切都很好,但是当我终止应用程序并从活动的onDestroy()中的服务解除绑定时,几秒钟后,我看到logcat中显示以下错误:

不太清楚这里发生了什么,因为活动和服务都已终止(onDestroy()已在这两种情况下执行)。我猜还是有线索?该服务确实创建并使用了Android MediaPlayer。

服务终止后,我也收到了ANR消息。

我的问题是应用程序的主要活动调用“bindService()”两次,一次在“startService()”之前,一次在“startService()”之后。

删除对bindService()的调用解决了这个问题。

BIND_AUTO_CREATE 你的旗帜 bindService 命令。不希望我的服务在任何时候自动启动,我只是没有使用

再说一次,我可能完全错了,但这是值得尝试的。
