I'm having issues getting Kivy FileChooserListView to work.

My Python script:

# check if on android and request permissions
from sys import platform
if platform == 'android':
    from android.permissions import request_permissions, Permission
    from android.storage import app_storage_path, primary_external_storage_path

    request_permissions([
        Permission.READ_EXTERNAL_STORAGE,
        Permission.WRITE_EXTERNAL_STORAGE
    ])


class MyLayout(Widget):
    pass

class k8(App):
    def build(self):
        return MyLayout()


if __name__ == '__main__':
    k8().run()

Buildozer.spec:

...
# (list) Application requirements
# comma separated e.g. requirements = sqlite3,kivy
requirements = python3,kivy,pillow,numpy,pandas,matplotlib,pyjnius
...

# (list) Permissions
# (See https://python-for-android.readthedocs.io/en/latest/buildoptions.html for all the supported syntaxes and properties)
#android.permissions = android.permission.INTERNET, (name=android.permission.WRITE_EXTERNAL_STORAGE;maxSdkVersion=18), MANAGE_EXTERNAL_STORAGE
android.permissions = MANAGE_EXTERNAL_STORAGE

When I run the app in android I get a black screen with two texts at the top, "name" and "size".

The error report I get in logcat:

adb logcat | grep python
...
23690 23732 I python  : PermissionError: [Errno 13] Permission denied: '/'

I think the issue is that my app doesn't have permission to access the files, I'm not sure what I can do to get access.

from android.storage import primary_external_storage_path
primary = primary_external_storage_path()
FileChooserListView(path=primary)
