How do I implement Firebase authentication in a React Navigation app for Android?

To implement Firebase authentication in your React Navigation app, first, ensure you have Firebase set up in your project. Then, you can use the Firebase Authentication SDK to handle user sign-in and sign-up.

What are the steps to set up Firebase in my React Native project?

1. Create a Firebase project in the Firebase console. 2. Add your Android app to the project. 3. Download the google-services.json file and place it in your android/app directory. 4. Install Firebase SDK using npm or yarn.

Can you show me an example of how to sign in a user?

Sure! You can use the following code snippet:

import auth from '@react-native-firebase/auth';

const signIn = async (email, password) => {
  try {
    await auth().signInWithEmailAndPassword(email, password);
    console.log('User signed in!');
  } catch (error) {
    console.error(error);
  }
};
