I created an application that uses Google Play Services to display a map and receive coordinates (Lat / Long) either automatically or by allowing the user to manually select a specific location on the map and long press to get that specific coordinate. I got the API key and put it in my manifest, all I have to do. The application works fine on my personal phone, shows a map with the current position and everything, but on another device used for testing, with the same Android OS (4.2) the map area is empty, but I can click "Get GPS", and still get my current Lat / Long. It just stops me from manually choosing a location. I was wondering if there is any API key that I must have in order to provide proper functionality on several devices, and maybe I just got one that will work on one device, or if this is due to the fact that one Does the device use my google account? When I make changes to the application and reinstall on my personal phone, it still works, but again, the same problem on other devices.
