After Android 11, how to obtain cpu usage within android application?

Target

• I want to monitor the CPU usage for my APP (global CPU usage is also okay for me) within android application.

Background

• After Android 11, the normal application cannot access to /proc/stat, and
• HardwarePropertiesManager cannot be used in normal application for the permission "android.permission.DEVICE_POWER" is only granted to system apps.
• All the solutions that I can obtain in google are the same with the above two methods.

Question

• So is there any way that I can obtain CPU usage within an android application after Android 11?
