Solution 1:

You don't have to use api key in android code.

You have to use this api key at server side to send notifications and use project number in android code to register device for GCM and obtain unique device id for receiving notifications.

• Register the Android app with GCM to receive Registration Id “RegId“
• Share “RegId” with the server
• Send a message from server to GCM using HTTP POST request
