For using any Google services in Android, we have to generate an API key or we have to generate some unique key for using that service provided by Google. So Maps is one of the famous and most used services provided by Google. Maps can be seen in each and every app provided by Google and we also can use that service to add maps to our app. So in this article, we will take a look at the process of generating an API key for using Google Maps.
