Wie verbinde ich meine geplante Android-App mit Kotlin und Jetpack Compose mit dem Firebase-Api, um einen Benutzer mit Google Auth zu authentifizieren?
To connect your Android application developed with Kotlin and Jetpack Compose to Firebase and authenticate users with Google Auth, follow these steps: + 1. Configure Firebase in your Android project 1. Go to the [Firebase] website (https://firebase.google.com/). and create an account or log in. 2. Create a new Firebase project and follow the instructions. 3. Add Firebase to your Android project by following the instructions in the [official document] (https://firebase.google.com/docs/android/setup). 4. Make sure to add the `google-services.json` file to your project. + 3. Add Firebase to your Android project by following the instructions in the [official document].(https://firebase.google.com/docs/android/setup. 4.

Use `AuthticationManager` in your application You can use the `AuthenticationManager` class in your application to manage user login and log-in closure. Here's an example of how to use it in a login screen with Jetpack Compose: {kotlin @Composable fun SignInInScreen(autificationManager: AuthenticationManager: AuthenticationManager) { val context = LocalContext.current value value signinininInLaunmemberLauncherForForActivityResult( contract = ActivityResultResultContractsContractscontractsContractsContractsContractsConvertsConvertsConvertsConvertsConvertsConvert
