如何查看哪些唤醒锁处于活动状态

问题描述

出于某种原因，我的 Android 手机无法进入睡眠状态.我假设唤醒锁使其保持唤醒状态，但无法判断哪些唤醒锁处于活动状态.正在运行的服务没有列出任何可疑的东西，当然也和平常没有什么不同.所以我的问题是:

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:

1. Android 一定会在进程结束时释放唤醒锁吗?是否有可能应用程序编写不当并且在退出前没有释放唤醒锁?

1. 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?

有什么办法可以看到活动的唤醒锁吗?

Is there any way to see the active wakelocks?

这是dumpsys power 显示的内容:

推荐答案

在新版本的 Android 中，您可以在此处查看唤醒锁列表:

In new versions of Android you can see list of wakelocks here:

adb shell "cat /sys/kernel/debug/wakeup_sources"
