How do I enable the RSA public key in Google Play Services in my binary Android application?

Question

First off, I'm an iOS developer. I am not an Android expert. I need to support one Android application project. About the issue of subscribing to the application, the rules between iOS and Android are so different!

At the moment, I know how to sign an Android app and publish it on Google Play.

BUT , I found this in the Google Play Developer Console -> my application -> Services and APIs:

They gave me this public key.

My question is : How and where to use this public key? I have already signed up my application using the ADT wizard.

This is an optional use item, if you want to use it to provide licensing requirements for each application, see Google Licensing here .

Basically, this is a system that allows your application to check Google’s servers with a public key and determine (based on the answer) how your applications ’behavior should continue (or not).

If you are not involved in the application of licensing restrictions, then this is absolutely not required in your latest apk.
