android - 如何在 Android 后台监控应用程序的传感器使用情况？

Question

Android 系统告诉应用程序的方式是在后台使用 GPS。
例如，我怎样才能以编程方式让一个应用程序告诉我除我以外的另一个应用程序正在使用麦克风或陀螺仪？该应用程序的目的是向用户展示一些关于后台应用程序/服务使用传感器的统计数据。

回答:没有root就不行

You could write an app to try and monitor what's happening on the device, but it would require elevated permissions for your app like running as System or requesting a large set of permissions, so that you could query the appropriate services and access system resources to guess at what other apps are doing. The packagemanager exposes api calls for determining the installed applications and even examining their permissions, At best though like mentioned in the earlier answer all apps run in their own instance of the dalvik vm.
