The error message you’ve posted indicates that there is an issue with Firebase initialization in your Android application. Specifically, it’s complaining that the Default FirebaseApp is not initialized in your process com.example.firebaseauth, and it suggests that you should call FirebaseApp.initializeApp(Context) first.

Here are the key points to address this issue:

Solution:
1. Firebase Initialization in Kotlin:
  Make sure you have properly initialized Firebase in your Android application. Firebase should be initialized in the onCreate method of your Application class or the first Activity that gets launched.
```
import android.app.Application
import com.google.firebase.FirebaseApp

class MyApplication : Application() {
    override fun onCreate() {
        super.onCreate()
        FirebaseApp.initializeApp(this)
        // Other initialization code if needed.
    }
}
```
2. Check Firebase Dependencies in Kotlin:
  Ensure that you have the Firebase SDK dependencies correctly added to your build.gradle file. Here’s an example in Kotlin:
```
implementation("com.google.firebase:firebase-auth:22.1.2") // Use your specific version
implementation("com.google.firebase:firebase-core:22.1.2") // Core Firebase SDK
// Add other Firebase dependencies if your app uses them.
```
3. Update Firebase SDK in Kotlin:
  Keep your Firebase SDK up to date. You can check for the latest version of Firebase SDKs and update your dependencies accordingly.
4. Rebuild and Clean Project in Kotlin:
  Sometimes, issues like this can be resolved by cleaning and rebuilding your project. Go to "Build" > "Clean Project" and then "Build" > "Rebuild Project" in Android Studio.
5. Check Proguard/R8 Rules in Kotlin:
  If you are using Proguard or R8 for code obfuscation and minification, ensure that you have the necessary rules to keep Firebase classes intact.
6. Check Application Id in Kotlin:
  Ensure that the application ID in your build.gradle file matches the one registered in your Firebase project. You can find the application ID in your google-services.json file.
7. Check for Duplicate Initialization in Kotlin:
  Double-check that you’re not calling FirebaseApp.initializeApp(Context) multiple times in your code.
By addressing these points using Kotlin code, you should be able to resolve the issue and ensure that Firebase is properly initialized in your Android app.
