Support Android 9+ #52

Closed lxwntr closed 5 months ago

lxwntr commented 5 months ago

I got the app to work on Android 9 and tested it on a real device.

The UI code needed minor changes to get window metrics on Android <11.

The backup function did not work on my device (access denied), so I rewrote it to use Intent.ACTION_CREATE_DOCUMENT (API level 19). This API uses streams (it can store, for example, to a cloud provider) and required a workaround to work with Zip4j because ZipOutputStream does not provide the addFolder method and requires iterating over and manually adding metadata+content for each file. I opted to keep using ZipFile with a temporary file and it gets copied to the destination.

No other changes were necessary and identification worked out of the box.

Closes #22, #50

Thanks, but it was on purpose that I decided to request Android 11 as minimum. Lower Android versions will increase the maintenance effort also for future features and I do not have time for that. So I do currently not plan to merge it. But if you like you can upload an apk in an Android 9 issue so others can download it.

For now I changed my mind. I had my code already changed, so merging did not work. But the feature is now integrated. https://github.com/woheller69/whoBIRD/commit/02baacafb2f6c1d328d4c4ca68dc77b10000743c

Hi @lxwntr ,

If you got some version to work on older Android versions could you provide an apk for me to try it out?

Thanks in advance
