How to resolve conflicts when integrating Firebase Cloud Message simultaneously?

When Call Kit receives a message from FCM, if the message is not from ZEGO SDK, it will send a broadcast to the current application with the action com.zegocloud.zegouikit.call.fcm. The sample code is as follows:

Intent intent = new Intent("com.zegocloud.zegouikit.call.fcm");
intent.putExtra("remoteMessage", remoteMessage);
context.sendBroadcast(intent);

Intent intent = new Intent("com.zegocloud.zegouikit.call.fcm");
intent.putExtra("remoteMessage", remoteMessage);
context.sendBroadcast(intent);

Therefore, if you have already integrated Firebase Messaging, simply follow these steps to complete the migration:

1. Create and statically register a BroadcastReceiver in your application:

   • Create a BroadcastReceiver, for example YourCustomBroadcastReceiver.java.
   • Register it to the application node of your application's Manifest.xml file and set the action to "com.zegocloud.zegouikit.call.fcm". The example is as follows:

   <receiver
        android:name="com.zegocloud.uikit.demo.calloffline.YourCustomBroadcastReceiver"
        android:enabled="true"
        android:exported="false">
        <intent-filter>
          <action android:name="com.zegocloud.zegouikit.call.fcm"/>
        </intent-filter>
    </receiver>

   <receiver
        android:name="com.zegocloud.uikit.demo.calloffline.YourCustomBroadcastReceiver"
        android:enabled="true"
        android:exported="false">
        <intent-filter>
          <action android:name="com.zegocloud.zegouikit.call.fcm"/>
        </intent-filter>
    </receiver>

2. Remove the original FCM Service from Manifest.xml. The example is as follows:

   <service
       android:name=".java.MyFirebaseMessagingService"
       android:exported="false">
       <intent-filter>
           <action android:name="com.google.firebase.MESSAGING_EVENT" />
       </intent-filter>
   </service>

   <service
       android:name=".java.MyFirebaseMessagingService"
       android:exported="false">
       <intent-filter>
           <action android:name="com.google.firebase.MESSAGING_EVENT" />
       </intent-filter>
   </service>

   Please remove it to avoid conflicts with Zego SDK.

3. Listen to and handle related events: You need to migrate the logic from MyFirebaseMessagingService to YourCustomBroadcastReceiver. The example is as follows.

   Original code:

   public class YourFirebaseMsgService extends FirebaseMessagingService {
        @Override
        public void onMessageReceived(RemoteMessage remoteMessage) {
            // Your custom logic
        }
    }

   public class YourFirebaseMsgService extends FirebaseMessagingService {
        @Override
        public void onMessageReceived(RemoteMessage remoteMessage) {
            // Your custom logic
        }
    }

   Please migrate as follows and delete YourFirebaseMsgService.java:

   public class YourCustomBroadcastReceiver extends BroadcastReceiver {
   
        private static final String TAG = "CustomReceiver";
   
        public void onReceive(Context context, Intent intent) {
            com.google.firebase.messaging.RemoteMessage remoteMessage = intent.getParcelableExtra("remoteMessage");
            // Your custom logic
            Log.d(TAG, "onReceive.remoteMessage.getData: " + remoteMessage.getData());
        }
    }

   public class YourCustomBroadcastReceiver extends BroadcastReceiver {
   
        private static final String TAG = "CustomReceiver";
   
        public void onReceive(Context context, Intent intent) {
            com.google.firebase.messaging.RemoteMessage remoteMessage = intent.getParcelableExtra("remoteMessage");
            // Your custom logic
            Log.d(TAG, "onReceive.remoteMessage.getData: " + remoteMessage.getData());
        }
    }

By following these steps, you should be able to receive and handle your own FCM messages.
