I have a key to enable Google Maps V2 on android, I did everything I had to do in Manifest and Gradle, when I run the application, the Google-named Fragment appears, but it does not loads nothing, it's in Beige light color, with nothing on the screen, however, the key I received by email from the company, where the same bought the license and sent me the key, I'm new with Google Maps and realized that to generate the key is necessary to have the SHA-1 of your developing PC, I am orienting myself through GOOGLE ANDROID 3rd edition > Novatec , and in it explains that to access the services of Google by cloud.google.com I would need to access with a gmail account, but there is the doubt, I did not generate the key, SHA-1 will be different, and the gmail account would not have to be from the person who bought the license?
The X of the question is, since I have the key, how do I enable and make it work in my app ???
Here is the image of the App:
