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:

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.
