I have a question regarding storage changes in Android 11. If I understand correctly, app can read/write/delete the files it created. Also I can then access those files for example like this:
File path = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS).toString() + "/ExampleApp/" + fileName);
ExampleApp is the app folder I created in the public Downloads folder.
But once the app gets uninstalled, it losses the ownership over all the files it created. Is there a way to regain the ownership of the ExampleApp folder by the app once it gets reinstalled?
One could use scoped storage & ACTION_OPEN_DOCUMENT_TREE, but that would then have to be done on every fresh start of application, no? Files in the app folder are in multiple sub-folders and of non media format, so I can't utilize Media Store API.
Permissions used:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
Scoped storage permissions:

No.

No. Programmers can use takePersistableUriPermission() on ContentResolver to get durable access to user-selected tree.
