In my app I'm using google maps. Now, I realized that you have a build google maps key and release google maps key. When I launch my signed apk into the app store for testing the google maps screen goes grey. And i have to keep signing a new apk and loading it into play store and then test it.
How do I test a release build? Please provide very simple and easy step by step instructions or if you know how to solve the problem with google maps that would be helpful.
Here is a screen shot of how i set up my google maps api in the console for my release one.
