Example of Android Push Notification with Firebase Console

This example demonstrates receiving push notifications from the Firebase
Console, and then displays the content on the screen in JSON format. You
can send push notifications to the devices running this example by using
the notifications composer in the Firebase Console. The Firebase servers
will notify the registered application that the new message is available
to sync.

+
+    \image pushnotification-example.png Screenshot of the example
+
+    \e {Firebase Cloud Messaging (FCM)} is a messaging solution. It reliably
+    delivers messages via the \e FCM servers. Using \e FCM, you can send
+    notification messages to notify a client app that a new message is available
+    to sync. To learn more, visit \l
+    {https://firebase.google.com/docs/cloud-messaging}.
+
+    This example demonstrates receiving push notifications from the \e {Firebase
+    Console}, and then displays the content on the screen in JSON format. You
+    can send push notifications to devices running this example by using the
+    notifications composer in the \e {Firebase Console}. The fields such as \e
+    message-text and \e custom-data are sent to this application in a payload
+    composed of key/value pairs.
+
+    To use this example, the user must install \e {Firebase SDK} to their
+    environment. See https://firebase.google.com/docs/android/setup
+    \note Set environment variable \e GOOGLE_FIREBASE_SDK to the root directory
+    of \e {Firebase C++ SDK}.
+    \note Download the registered \c google-service.json from the \e {Firebase
+    Console} and save it as \c android-sources/google-services.json, replacing
+    the sample file.
