Building an Android app to receive push notifications

A push notification works in the same way as iOS for Google; however, instead of using the Apple Notification Service, you will be working through the FCM server, which is a new replacement for Google Cloud Messaging (GCM). However, OneSignal abstracts this process so that you don't have to code using a different API. You will be using the same push object as for the iOS app.

Note

For more information about the differences between FCM and GCM, visit the FAQs at https://firebase.google.com/support/faq.

In this section, you will learn how to do the following things:

• Set up OneSignal for Android push notification
• Configure the Firebase project for the push API
• Write code to receive push notifications on Android

You will be using the same code base as your iOS push notification example. The main difference is the process to set up in your Firebase and OneSignal account.

Getting ready

You can test the Android push notification using the Android emulator...
