I still have to test this myself, but this looks very promising and helpful for something I want to do in my app. The code is very clean and easy to understand. Edit: I'm not authorized to use this specific google api. That's too bad. I still agree to the statement I made earlier. It's a good tutorial.

[@DanaiKamvoussiora]

Maybe you have restricted the api key you used to just one API function. Or maybe you haven't enabled the Directions API on your account.

[@LucasFilmtDoor]

@@DanaiKamvoussiora I was indeed using it for something else already (the location of the device), but my edited part was what I made up from the error notifications and the support on Google API's.
