How do I use Crashlytics for my React Native Android App?

Question

I am trying to figure out how to use Crashlytics from Fabric for my React Native Android APP. I followed the steps on the Fabric homepage and added some lines in my build.gradle files. But the builds always crash.

Is there a difference using Crashlytics for React Native Android and Crashlytics for Native Android development using Android Studio and Java?

Answer 1

For the newer versions of React Native you have to import Bundle and place your own onCreate Method like this:

// Added Bundle to use onCreate which is needed for our Fabrics workaround
import android.os.Bundle;

..........

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // Fabrics
    Fabric.with(this, new Crashlytics());

}

Not sure if this is good or not since they have removed the onCreate but it works for me
