この方法を試した方はいますか？

1. Downloaded the Xposed Framework installer located at:
https://forum.xda-developers.com/xpo...aller-t3137758
2. Get some sort of File Explorer app. I personally recommend ES File Explorer.
2. Install APK normally with either browser or file manager app (ex: ES File Explorer)
3. Open app and go to official tab.
4. You should see something that looks like xposed-v87-sdk22-arm, next to it there should be a little downward facing arrow.
Click on it.
5. Select xposed-v87-sdk22-arm64 from the dropdown menu.
6. Click on Install or Install/Update
7. By now you should see a little console window popped up displaying that there was an error finding "app_process64". This is normal.
8. Go to home screen and open your File Explorer app.
9. Navagate to /system/bin/ and delete the file: "app_process64_xposed"
10. Reboot your tablet ("Optimizing System blah blah blah" is normal when booting.)
11. Open the Xposed installer app we downloaded earlier
12. If you see a green box with a checkmark in the middle it worked!
