Since Google already fixed this method, System tracing will not works if the Android System WebView application is at version 114.xxx or above So you need to uninstall the update.

After you done uninstall the update, recommend to turn off auto update apps your Google Play Store

HOW TO SOLVED ERORR

Permissions denied
- It's means you don't give permission on termux ( You can manually give permission, Apps info > permissions > files > allow)
strings: 'testing.txt': No such file
- It's means you wrong save the file, name not match
- If you open via Qute probably you don't give permission, you can enter ls for check it or version android system WebView apps 114.xx
If after you enter script and nothing appear
- Try check category settings and only check list WebView
- Go apps management and see version android system WebView if already install version 114 you need to uninstall the update and tracing again
- Set CPU log buffer trace to 32
- Before you end tracing try see 2-3 page gacha history
If gacha link not fully appears
- change the script ~~tail -2~~ to head -2 or the other way around
If after you uninstall the update android system WebView and Games can't open, You can force stop Your games or restart your phone

IF YOU'VE FOLLOWED THE INSTRUCTIONS AND IT'S STILL NOT WORKING, THERE MAY BE SOMETHING WRONG WITH YOUR INSTALLATION PROCESS OR A PROBLEM WITH YOUR DEVICE.
