调试Android振动 [英] Debug Android vibration

问题描述

我的手机没有任何理由振动。所以我想确定发送振动命令振动的应用程序。 Android是否会记录此类事件？或者我可以编写一个应用程序来监视另一个应用程序的 Vibrator :: vibrate（TIMEOUT）呼叫吗？

Guys my phone is vibration without any reason. So I want to determine the application which sends vibration command to vibrate. Does Android logging such events? Or can I write an application which will monitor Vibrator::vibrate(TIMEOUT) calls from another application?

注意：
我具有root访问权限。

Note: I have root access.

推荐答案

如果您查看系统日志（ logcat -b system ），它将显示核心系统服务的日志。 VibrateService仅在最新版本的Android中有一对，它将告诉您正在启动哪种振动模式。不幸的是，它不会向您显示负责该请求的UID / PID。除此之外，您还可以通过挖掘来找出振动器使用的设备接口（例如 / dev / gpio1 ）来从内核中找到一些信息。服务。如果该驱动程序公开了 / proc 或 debugfs 上的某些统计信息/调试，则您可能能够确定哪个进程负责

If you look in the system log (logcat -b system) it will show you the core system service's logs. The VibrateService only makes a couple in the latest version of Android, which will tell you what vibration pattern is being started. Unfortunately, it won't show you what UID/PID is responsible for the request. Beyond that, you may be able to find some information from the kernel by digging around to figure out which device interface (e.g. /dev/gpio1) is the one used by the vibrator service. If that driver exposes some stats/debug on /proc or debugfs you might be able to figure out which process is responsible.
