WHICH PERMISSIONS DOES GEOLOGGER NEED?

+ Permission "INTERNET"

GEOLOGGER needs to download map data from OpenStreetMap servers and therefore needs access to the internet.

+ Permission "ACCESS_NETWORK_STATE" and "ACCESS_WIFI_STATE"

GEOLOGGER uses osmdroid to draw its maps. osmdroid needs to know the current state of your device’s connectivity.

+ Permission "ACCESS_COARSE_LOCATION" and "ACCESS_FINE_LOCATION"
