Registering the google api key for publishing app

When we are ready to publish your application,we must get a Maps API Key that is based on the certificate that be will used to sign the application for 开发者_JS百科release n then change the Maps API Key strings referenced by all of MapView elements, so that they reference the new Key.

But my problem is how to get the api key for publishing based on the certificate.
