Android has nice and useful services to backup application data, where is any way to kodi is registered?
Backup Service can be very useful to to store 
:
– DB
– user data setting (advancedsettings.xml, playercorefactory.xml ecc.. )
– network Shared link
so every time update/restore firmware kodi is auto-setup.
i find that Google report 3 type of back-up:
– Android Backup Service
– Auto Backup for Apps for Android 6.0 (API 23)
– Backing up App Data to the Cloud ( google drive )
thanks
