I did try that method but for some reason it wouldn't install. Seemed like it was conflicting with an already installed app (had already uninstalled it) so by using Android studio I could change the package name at the same time.
Also did see some people mention it might be a bad idea to give your API key out to randos on the internet which is fair enough.
Yea thats true, and tbf I did give them mine and i've not had my identity stolen as of yet lol.
The main reason I did mine manually was that I was getting a conflict error when installing so i wanted to change the package name too.
I ended up basicly using the Collab thing as a guide on what to change so it did come in handy.
