Error saving files/changing media save location

[gliffs]

I try to save any sort of media from any board, and I get a popup notification that says "save failed".
When I try to change media save location, the app crashes and force closes.
I verified the app has media save permissions in Android 2x, by reinstalling and checking the permissions manually in application settings.

Pixel 2 xl on Android q beta 5
fresh install of current Kuroba release. recreated the issues and pasted the logs.

Try opening Settings -> Import/Export. You will be asked to give your permission to write to external storage. Give the permission then try changing directory/downloading an image again.

I verified the app has media save permissions

It should be WRITE_EXTERNAL_STORAGE.

The app said "error trying to export settings permission denied"
Now I looked in the app permissions and it says nothing was denied. I gave it permission to view/modify media and I'm still getting the error.

Something is wrong. Try reinstalling the app and opening Settings -> Import/Export again. It should show you the permission window. If it doesn't then it's some kind of weird bug. I have exactly the same phone and Android Q Beta 5 too and everything works.

[gliffs]

That's exactly what I did. The permissions window did pop up, I tapped accept, and I'm still getting the error

[K1rakishou]

This should have worked. This is either an Android beta bug or there is something wrong with your phone. I'm afraid I don't know what else to suggest to you.

[Adamantcheese]

I suspect that the changes mentioned here https://developer.android.com/preview/privacy/scoped-storage are what's messing with it. It does say that Q B5 shouldn't have any issues with storage however, however I'll add in that manifest attribute just to be sure.

[K1rakishou]

Scoped storage has been posponed until Android R. So it shouldn't be it. And I have Android Q Beta 5 too and don't have this problem.

[Adamantcheese]

Hey, just double checking, but does this still occur with that manifest attribute added in?

[Adamantcheese]

Since that didn't seem to work (or I'll assume it didn't due to a lack of response), I'm going to close this and bump it to API 29 later on when #172 is implemented, which should fix the problem.
