GPS permissions on ANdroid requested by App, but no request is displayed to user

[Gary Kuipers]

I have another app that uses this code but I apparently missed something important becasue I am getting the following when requesting and then checking permissions:

MAIN: Permissions gps_fine_permission=False
MAIN: Permissions gps_fine_permission=False after request
MAIN: Permissions gps_coarse_permission=False
MAIN: Permissions gps_coarse_permission=False after request
