Push notifications in an Android mobile app

To enable push notifications for your Android custom app, obtain and then set certain parameters in the certificate set that is associated with the Android app.

Provide the following information:

• Sender ID – a Google Cloud Messaging (GCM) services identifier used to authenticate an Android custom mobile app with the Android Push Notification Integration services.
• Server API Key – a key used by the server to authenticate with the Google Cloud Messaging (GCM) services.

To obtain these values, log in to the Google Developer Console website, select an existing project or create a new project, and enable the Google Cloud Messaging for Android in the APIs section. Refer to the Google Developer documentation for assistance with this process.
