how can i solve GoogleApiManager SERVICE_INVALID for App with Location permission?
i'm new to coding and as a final project on a course I decided to build and Android app, since it's what I want to focus my studies later (kinda regret it now...).
My idea is about an app that will have GPS services and actions based on GPS locations, so I started following tutorials from the basics up, now i'm following a basic tutorial about a GPS app (in Kotlin) that just displays the current location with an on/off switch.
I'm still getting familiar with Android Studio and all the methods...
