Google yesterday announced a great new feature for Android app auto backup and restore (similar to what iOS already has):
Auto Backup for Apps makes seamless app data backup and restore possible with zero lines of application code. This feature will be available on Android devices running the upcoming M release. All you need to do to enable it for your app is update the targetSdkVersion to 23
That seems like it should be trivial to implement. Can anyone from Corona confirm when this will be supported? Thanks!
