Export settings now retries when file access permissions are granted.

Should fix #705? On my machine/test device running Android 10, I needed to change AndroidManifest.xml to get the fix to work reliably from a clean install, but didn't discover that until I had already pushed the other change 🤦‍♀️ sorry!

Hey,
Sorry it took me so long. I currently really only have time for this on the weekend and the last two weekends...

Anyway, the change you sent would in theory fix the issue, yes. However as on Android version 30, the requestlegacyexternalstorage option will no longer work (see https://stackoverflow.com/questions/63364476/requestlegacyexternalstorage-is-not-working-in-android-11-api-30). We will have to use A30 as soon as November, so in around 4 months.

So while this is a solution for the very short run, this will not really help longer than that.

I've looked a bit into this and tried changing it to use getExternalFilesDir() instead but that basically dumps it into a folder most users won't be able to touch.
I guess the best would be to use the MediaStore and save it as MediaStore.Files maybe?

Can you try to refactor the code to use that?

Absolutely, I'll try to put that together in the next couple weeks. Thanks for looking into everything :)
