Android. Google Maps API v2 Release key. Where to dig?

Question

Android

There is an application in development mode, with a map. Everything works great. But, when creating a release

Answer 1

Create two separate API KEYs in the console (one based on the release key, the second based on the debug key)
You can take the debug key in the .android folder, and put it in the project folder.
Next in build.gradle add to the android section:
signingConfigs {
debug {
storeFile file("debug.keystore")
}
}
