Kivy App on Android not asking for permission

[Carsten Thielepape]

Hi,

my Kivy App on Android is not asking for permissions on first App start. I fact,, my app needs the WRITE_EXTERNAL_STORAGE permission. The permissions I need are properly in the buildozer.spec file:

When I look into the APKs manifest file, the permissions are there as well

Just on App start, there is no popup coming to ask the user to grant the permission. If I manualy grant the permission after App installation and before App start. everything works fine. Is this something, the Kivy App need to care about itself in the code?

Runtime permissions

With API level >= 21, you will need to request runtime permissions to access the SD card, the camera, and other things.

This can be done through the android module which is available per default unless you blacklist it. Use it in your app like this:

from android.permissions import request_permissions, Permission
request_permissions([Permission.WRITE_EXTERNAL_STORAGE])

It is found in the latest python for android document:
