In the first chapter, we learned how to set up a development environment to kick-start an app development process. In order to install our Google maps application, we need to register our maps application in the Google Developer Console with our SHA1 fingerprint. This can be obtained by using the Java keytool and it is used in an authentication process. Let's learn about it in detail in this chapter.
In this chapter, we will cover the following topics:
Generating the SHA1 fingerprint on Windows, Linux, and Mac OS X
Registering our application in the Google Developer Console
Configuring Google Play services with our application
Adding permissions and defining the API key
Creating our first map application
