出于某种原因，我的Andr​​oid手机不会进入睡眠状态。我认为一个wakelock是保持其清醒，但目前还没有办法知道哪些wakelocks活跃。正在运行的服务没有列出任何可疑的，肯定没有什么异于往常。所以，我的问题是：

难道Android的绝对释放wakelocks进程结束时？是否有可能一个应用程序被写的不好并在退​​出之前没有发布wakelock？

有没有办法看到积极wakelocks？

解决方案

Android不释放wakelocks当过程结束。它应在结束之前明确释放通过的过程。

For some reason my Android phone won't go to sleep. I assume that a wakelock is keeping it awake, but there is no way to tell which wakelocks are active. The running services doesn't list anything suspicious, and certainly nothing different from usual. So my questions are:

Does Android definitely release wakelocks when a process ends? Is it possible an app was badly written and didn't release a wakelock before exiting?

Is there any way to see the active wakelocks?

This is what dumpsys power shows:

Android does not release wakelocks when the process ends. It should be explicitly released by the process before ending.
