To me, it feels a bit strange to store settings but not the actually important things – the subscriptions. We already have an open issue for backing up the subscriptions: Store list of subscriptions (possibly settings) through Google's Auto Backup for Apps · Issue #1899 · AntennaPod/AntennaPod · GitHub There is also some code that looks like it does something like this: AntennaPod/storage/importexport/src/main/java/de/danoeh/antennapod/storage/importexport/OpmlBackupAgent.java at develop · AntennaPod/AntennaPod · GitHub I don’t know if the code works, though. I don’t upload my app data to Google
In my opinion, backing up the settings is quite a low priority change. It might even be an advantage that users are reset to the default settings when changing devices. That way, potentially “misconfigured” settings get changed back to the default.
