Migrate from gcm to fcm in the server

问题

in this article (https://developers.google.com/cloud-messaging/android/android-migrate-fcm#update-server-endpoints) it says that for migrating from gcm to fcm all you need to do in the server is change the endpoint.

but how do i do this?

currently i'm using gcm client library for Java. what exactly do i need to do? i couldn't find anywhere instruction how to update the endpoint.

do i need to stop using the gcm client library and move to the fcm client library?

回答1:

There is no FCM client library. It is actually supported by the one you already use.

You can specify to which endpoint a message should be sent in the constructor for Sender.

Sender sender = new Sender(apiKey, Constants.FCM_SEND_ENDPOINT);
Message message = new Message.Builder()
    .addData("message", "a message")
    .build();
Result result = sender.send(message, registrationId, numberOfRetries)

Note that if you do not specify an endpoint, it defaults to FCM.

If you are using a recent version of the lib, you probably don't have to change anything.
