Sample Google Licensing Output

Google Play Licensing is a network-based service that lets an application query a trusted Google Play licensing server to determine whether the application is licensed to the current device user. The licensing service is based on the capability of the Google Play licensing server to determine whether a given user is licensed to use a given application. Google Play considers a user to be licensed if the user is a recorded purchaser of the application.

This application checks whether its downloaded from google play and accordingly show message to the user in the textview. If user is to be allowed access we show "Allow the user access" in textview. If user has not downloaded from the play store and has another apk we show "Don't allow the user access".
