The Realtime Framework Pub/Sub messaging system

Part of the The Realtime® Framework, Realtime Cloud Messaging (aka ORTC) is a secure, fast and highly scalable cloud-hosted Pub/Sub real-time message broker for web and mobile apps.

If your website or mobile app has data that needs to be updated in the user’s interface as it changes (e.g. real-time stock quotes or ever changing social news feed) Realtime Cloud Messaging is the reliable, easy, unbelievably fast, “works everywhere” solution.

The Android + FCM Push Notifications sample app

This sample app uses the Realtime® Framework Pub/Sub Android library to connect, send and receive messages through a Realtime® Server in the cloud. Through the integrated use of Firebase Cloud Messaging (FCM) messages are delivered to users as push notifications when the app is not running.

###This app is compatible with the iOS sample. See https://github.com/realtime-framework/MessagingObjectivecChat

NOTE: For simplicity these samples assume you're using a Realtime® Framework developers' application key with the authentication service disabled (every connection will have permission to publish and subscribe to any channel). For security guidelines please refer to the Security Guide.

Don't forget to replace YOUR_APPLICATION_KEY with your Realtime application key and YOUR_FIREBASE_SENDER_ID with your Firebase Sender ID in the Config.java file. If you don't already have a free Realtime® Framework application key, get one now.
