When I create the /storage/emulated/0/com.boardbeard folder (and a sub-folder), the ExternalMedia::getMediaFolders() function does not detect the sub folders. Also writing the readme.txt does not work.
I manually set the storage permission of the app, but this also didn't change its behavior.
Unfortunately, I don't have any experience with the storage permission handling in android.
The app has issues with Android API 26 (Android 8.0) and newer with the access to the external storage.
In https://github.com/nibuen/SpaceAlertMissionGenerator/blob/678a6957a39e0c2ede494579f8ac0033ea6ea42b/app/src/main/java/com/boarbeard/io/ExternalMedia.java#L18 the
dir.mkdirs()
is executed, but no directory is created. Then opening the file for the readme.txt results in an exception.When I create the /storage/emulated/0/com.boardbeard folder (and a sub-folder), the
