For now it's better if you just read the source/code.
JavaStream(input_stream)
SystemFileChooser(mime_type, multiple)
uri_to_extension(uri)
uri_to_filename(uri)
uri_to_stream(uri)
uri_image_to_texture(uri)

Permissions and Runtime-permissions

You don't have to state anything.

Example code of use

from androidssystemfilechooser import (SystemFileChooser,
                                       uri_image_to_texture,
                                       uri_to_extension,
                                       uri_to_stream)
from kivy.app import App
from kivy.core.image import Image as CoreImage
from kivy.lang import Builder
from kivy.properties import StringProperty
from kivy.uix.button import Button
from kivy.uix.image import Image

KV = '''

        multiple: True
        text: 'Choose and execute results!'
