问题
So let me start by telling you what works...
in the Buildozer Spec File I have: android.permissions = WRITE_EXTERNAL_STORAGE, READ_EXTERNAL_STORAGE, INTERNET
and in my code I have: from android.permissions import request_permissions from android.permissions import Permission request_permissions([Permission.WRITE_EXTERNAL_STORAGE, Permission.READ_EXTERNAL_STORAGE])
When I run the app for the first time it asks me (as a user) to grant permission to access storage.
On the Samsung Tablet I'm running AndroidOS 7.1.1 I can now create Folders on the INTERNAL memory and copy files to the Internal Memory (which is also referred to as external sd memory also for some reason.) But I can NOT create a folder on my removable SD card. Why?
Same on my Amazon Fire Tablet HD10 9thGen running FireOS 7.3.1.6
But on my Phone running AndroidOS 10.0 I am unable to create a folder or write files to any directory outside of my private app related folder in the root directory that I don't have access to. But I think I know why. Because of the new rules. Which I still haven't figured out yet how to grant permissions yet.
But I think first I would like to solve the problem of why I can write to my internal sd memory on AndroidOS 7.1.1 after permission is granted but WHY I am denied the ability to write to the removable sd memory. Like I stated above all permissions have been coded and granted. So what am I missing?
