Send push notifications from server with FCM
Recently I asked a question on sending push notifications using GCM: Send push notifications to Android. Now that there is FCM, I am wondering how different it would be from the server side development. Coding wise, are they the same? Where can I find example FCM codes showing sending push notifications from server to Android device?
Do I need to download any JAR library for sending notifications to FCM using Java codes? The example codes in Send push notifications to Android shows sending push notifications using GCM and a server side GCM JAR file is required.
However, another example in https://www.quora.com/How-do-I-make-a-post-request-to-a-GCM-server-in-Java-to-push-a-notification-to-the-client-app shows sending push notifications using GCM and no server side GCM JAR file is required since it is just sending via an HTTP connection. Can the same codes be used for FCM? The URL used is "https://android.googleapis.com/gcm/send". What would be the equivalent URL for FCM?
Thanks in advance.

How different is server-side coding?
Since there is not much difference, you can just check out most of the example server-side codes for GCM as well. Main difference with regards to GCM and FCM is that when using FCM, you can use the new features with it (as mentioned in this answer). FCM also has a Console where you can send the Message/Notification from, without having your own app server.
NOTE: Creating your own app server is up to you. Just stating that you can send a message/notification via the console.
The URL used is "https://android.googleapis.com/gcm/send". What would be the equivalent URL for FCM?
The equivalent URL for FCM is https://fcm.googleapis.com/fcm/send. You can check out the this doc for more details.
