  1. Add the android package name, the application nickname and the SHA-1 details. Click on the Register App button once the details are entered. Click on ‘Download google-services.json’ button to get the google-services.json file’. Add the file to the root directory of your project. Add the dependencies as mentioned to the gradle files.

  1. Refer https://firebase.google.com/docs/cloud-messaging/android/client to configure your mobile app to receive the push notifications.

  2. You need to subscribe to a channel from where you will get the push notification. You will get this channel from the response received in gotProfileInfo() callback when you call the subscribe method using the SDK.The response of callbacks contains a key named as “push_channel”. This contains the push notification channel. You can subscribe to push channel using the following line:

  1. For push notifications in the group, you will get “push_channel” from the response received in success callback of the joinGroup method. Once you subscribe to this channel, you will start receiving push notifications for the group.

  2. For push notifications in Announcement, you will get “push_an_channel” in the response of gotProfileInfo() callback when you call the subscribe method using the SDK. In the response, you will receive a key named ‘push_an_channel’. Once you subscribe to this channel you will start receiving the push notification for announcements sent from CometChat administration panel.
