In this tutorial, we walk you through the steps to configure Firebase Cloud Messaging (FCM) with brainCloud.
- Must have created an app on the Firebase console
Use the FCM API key for brainCloud
Get the FCM Server Key
- Navigate your browser to the Firebase console
- Select your app
- Click the Settings Icon, “Project Settings” in the top left nav bar.
- Select “Cloud Messaging” and copy the Server Key
Save the Server Key in the brainCloud Portal
- Navigate to the brainCloud portal and enter this key in the Notifications | Settings for Google Play.
Enable FCM For Your App
In addition to the above steps, you will need to do the following in order for FCM to work in your app.
Get the google-services.json file
This file can be found in the Firebase dashboard, and contains most the credentials you’ll need to connect your app to Firebase.
- Navigate to the General Tab in the Firebase Project Settings
- Download the google-services.json file
- Add the downloaded file to your app
- If using Unity, you can use the brainCloud example at this link. Be sure to add change the App Id and Secret to your own
Registering FCMNotification Token With brainCloud
After Authenticating a user with brainCloud, you will want to Register their FCMnotification token with brainCloud. Specifically, you’ll want to call the BrainCloudPushNotifications.RegisterDeviceToken() and pass in the registration id. In order to get this registration id, follow these steps.
Note that this example assumes you are working in Java on an Android device. For developers using Unity (or a Unity plugin such as GamePlayServices), follow the appropriate instructions available elsewhere.
- A starting example project can be found here: https://github.com/firebase/quickstart-android/tree/master/messaging
- Use the FirebaseInstanceId to get the token
- Pass that token into the brainCloud Push Notification Service
String token = FirebaseInstanceId.getInstance().getToken(); bc.PushNotificationService.registerPushNotificationToken(Platform.GooglePlayAndroid, token, self);
