How Shizuku is used

Can show a live FPS overlay for the foreground app via `dumpsys` shell commands.

This is an AI-assisted analysis of Shizuku-related usages in the app's public source code. It is best effort, so it may not catch every single usage.

How this app uses Shizuku

Shizuku is used to collect frame rate and foreground app information for the floating FPS display.

Show live FPS overlay: shows the current frame rate of the foreground app in a floating window, using hardware frame rate files plus dumpsys SurfaceFlinger, dumpsys gfxinfo, dumpsys activity and dumpsys window shell commands through Shizuku.

Changelog

What's new for version 1.0

Version: 1.1 I apologize for the app not measuring accurately before; I created it just for entertainment and didn't focus on it. => Now it measures much more accurately with Shizuku/Adb/Root permissions. I tested it with two devices: a Samsung A9 2018 (60hz) and a Nubia Neo 5G (120hz).The results I think are correct or incorrect. Please use them and let me know the results. Thank very much..!
