FCM Vs GCM? Why we need to migrate from GCM to FCM

  1. Why we need this FCM.

Answer : FCM (Firebase Cloud Messaging) is a improved version of the Google Cloud Messaging API & it have all features of GCM with some additional features also. Google recommending this, they wrote “Firebase is known for being cross platform, so FCM now makes a natural fit in the Firebase suite of features designed for Android, iOS, and mobile web”. Google just announced that Google Cloud Messaging is now Firebase Cloud Messaging. See new Release Source URL : https://developers.google.com/cloud-messaging/faq

  1. FCM over GCM.

Answer : FCM is the new version of GCM under the Firebase brand. It inherits GCM’s core infrastructure, with new SDKs to make Cloud Messaging development easier. Benefits of upgrading to FCM SDK include:

Simpler client development. You no longer have to write your own registration or subscription retry logic. An out-of-the-box notification solution. You can use Firebase Notifications, a serverless notifications solution with a web console that lets anyone send notifications to target specific audiences based on Firebase Analytics insights.

  1. Is GCM now depreciated. Are they going to stop all services & support of gcm.

Answer : Yes some features of GCM is already depreciated and now in coming days GCM are going to fully depreciated. See here , But Google says We will continue to support the current version of GCM Android and iOS SDKs because we know a lot of developers are using GCM SDKs today to handle notifications, and client app upgrade takes time. But all new client-side features will be added to FCM SDKs only moving forward. You are strongly encouraged to upgrade to FCM SDKs. Source URL : https://developers.google.com/cloud-messaging/faq
