Google Cloud Messaging Quickstart

Google Cloud Messaging Android Quickstart app demonstrates registering an Android app for GCM and handling the receipt of a GCM message. InstanceID allows easy registration while GcmReceiver and GcmListenerService provide simple means of receiving and handling messages.


Getting Started

  • Follow the quickstart guide to set up your project in Android Studio.
  • Run the sample on your Android device.
  • Update API_KEY in GcmSender.java, with API key from your project.
  • Run the terminal command to send GCM message to your device.
  • A notification containing the GCM message should be displayed on the device.


The GcmSender module in this project is emulating a server for the purposes of this sample, but it's not meant to serve as an example for a production app server. For information on GCM server implementaion see About GCM Connection Server
