I'm trying to implement firebase notifications. But I have trouble finding any documentation on how to retrieve custom data from firebase notification.
But in in code how to get the custom key.
I'm using FirebaseMessagingService.onMessageReceived
to get the message data.
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
// TODO(developer): Handle FCM messages here.
// If the application is in the foreground handle both data and notification messages here.
// Also if you intend on generating your own notifications as a result of a received FCM
// message, here is where that should be initiated. See sendNotification method below.
Log.d(TAG, "From: " + remoteMessage.getFrom());
Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());
}
You can check your custom data using:
for (Map.Entry<String, String> entry : remoteMessage.getData().entrySet()) {
String key = entry.getKey();
String value = entry.getValue();
Log.d(TAG, "key, " + key + " value " + value);
}
To get specific key:
String value = remoteMessage.getData().get("<YOUR_KEY>");
