Firebase Cloud Messaging Android App

This is a sample Android project to showcase the Firebase Cloud Messaging (FCM) to manage upstream and downstream messages. To be precise, it is the client project for my XMPP Connection Server for FCM. The objective is to have an end-to-end testing:

1. Upstream message: Android - FCM CCS - XMPP Client Server.
2. Downstream message: XMPP Client Server - FCM CCS - Android.

What this project does?

Android

• Send upstream messages to the XMPP Client Server.
• Handle push notifications.

PHP

• Register tokens from devices into the database.
• Get the list of tokens from the database.
• Send push notifications to registered devices.

Firebase

XMPP Client Server

• Send downstream messages to a device. Java implementation.
