7.0(0)

Upgrade the application to build and run with minimum API 28 (Android Pie 9.0) and target API 30 (Android 11) as well as remove support for older devices

This was not an easy decision but Google’s stricter rules left me no choice. The new document management system which became mandatory with API 29 (Android 10) and is fundamentally incompatible with the previous system so making the code work with both the old and new Android versions just to much work for a single programmer hobby project.

Note that some storage locations won’t be available on Android 11 and beyond as the new security system won’t allow easy access to them.

Last not least support for older devices had to be removed as Google started to apply the new rules to old releases.

Personal note: This was and still is all quite a lot of unnecessary work. Why Google had to make everyone’s live difficult with incompatible updates to the API and Play-Store is beyond me.

Version 6 #

6.9(1)

(beta test version for upcoming 7.0(0)) Upgrade the application to build for target SDK Version 29. This is not the newest Version but this intermediate step is needed as Google made several rather drastic changes to both the build system and the application programming interface. And for now I need legacy external storage as changing the storage system is quite a lot for work.
