Google's Android 11, and Amazon's Fire OS 8.1 implement "Scoped Storage" which removes the ability of the adb program to access /sdcard/Android/data/.
This has the unfortunate side-effect of preventing adblink from accessing Kodi's data located at /sdcard/Android/data/org.xbmc.kodi. This means no backup/restore, no cloning, no edit of xml files, etc.
Luckily, Kodi allows us to relocate its data to an accessible location. If adblink determines that the file location /sdcard/Android/data is sandboxed it will instruct Kodi to look for its data at /sdcard/kodi_data/ via the text file /sdcard/xbmc_env.properties file which adblink will create. Kodi will read this file at startup to determine its data's location.
Additionally, when restoring a backup to a Android 11 device, adblink will set the MANAGE_EXTERNAL_STORAGE permission to "allow" which will permit Kodi to read the xbmc_env.properties file at startup. Otherwise Kodi is not permitted to access local files outside of its sandbox.
If you need to grant or revoke the MANAGE_EXTERNAL_STORAGE permission manually, you can do this for Kodi or any app via adblink's Utility menu function: "Set app permissions" seen in the dialog above.
