My React native app (using Expo) is working perfectly fine with Firebase SDK in the Expo Go app. (auth, firestore queries, storage, etc)

But as soon as I build the app as an apk using: "eas build -p android --profile preview", the app installs and opens and crashes on launch - meaning a blank screen appears and the app closes by itself.

After several debugging and builds and trial and errors, I've determined the Firebase SDK is causing the crash. When I removed Firebase npm from my project, the app builds and runs fine, but with Firebase it crashes.

My question is, in a RN Expo app, does the Firebase SDK work properly (versions below) or does react native expo only support the @react-native-firebase library?

I'm using:

• expo: "~52.0.38"
• react: "18.3.1"
• react-native: "0.76.7"
• firebase: "^10.13.1"

• Please provide the crash trace log. It will help us to figure out what went wrong. – Sally Azulay Commented Mar 12 at 19:32
• there are none! it just crashes on launch and works fine in expo go – Scorpion Edge Commented Mar 12 at 20:17

Hope that you'll find your solution here.

If you're using PendingIntent for a notification, update your code as follows:

PendingIntent pendingIntent = PendingIntent.getActivity(
context, 
0, 
intent, 
PendingIntent.FLAG_IMMUTABLE // or PendingIntent.FLAG_MUTABLE if needed

);

If you are using Firebase Cloud Messaging (FCM):

  @Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    Intent intent = new Intent(this, YourActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    
    PendingIntent pendingIntent = PendingIntent.getActivity(
        this, 0, intent, PendingIntent.FLAG_IMMUTABLE
    );

    NotificationCompat.Builder notificationBuilder =
        new NotificationCompat.Builder(this, CHANNEL_ID)
            .setSmallIcon(R.drawable.ic_notification)
            .setContentTitle(remoteMessage.getNotification().getTitle())
            .setContentText(remoteMessage.getNotification().getBody())
            .setAutoCancel(true)
            .setContentIntent(pendingIntent);

    NotificationManager notificationManager =
        (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

    notificationManager.notify(0, notificationBuilder.build());
}

Hope that helps.
