```
classpath 'com.google.gms:google-services:4.3.15'
```
Add Firebase SDK Dependencies (App): Add the required Firebase SDK dependencies to your project's build.gradle (Module: app) file. For example, to use Firebase Authentication and Realtime Database, add the following lines to the dependencies block:
```
            implementation platform('com.google.firebase:firebase-bom:32.8.0')
            implementation 'com.google.firebase:firebase-analytics'
            implementation 'com.google.firebase:firebase-auth'
            implementation 'com.google.firebase:firebase-database'
        
```
*Note that the firebase-bom and sdk versions can vary and should be checked for latest version.
Apply the Google Services Plugin: Add the following line to the top of your project's build.gradle (Module: app) file, below the plugins block:
```
apply plugin: 'com.google.gms.google-services'
```
Sync Gradle: Sync your Gradle files to apply the changes.

Your Android project is now connected to Firebase! You can start using Firebase services in your app.

Practical Examples: Using Firebase Services in Your Android App

Let's explore some practical examples of how to use Firebase services in your Android app:

1. Firebase Authentication

Firebase Authentication simplifies user authentication with various providers. Here's how to implement email/password authentication:

Enable Email/Password Sign-in: In the Firebase Console, go to "Authentication" -> "Sign-in method" and enable the "Email/Password" provider.

Implement Registration:


            FirebaseAuth mAuth = FirebaseAuth.getInstance();
            mAuth.createUserWithEmailAndPassword(email, password)
                    .addOnCompleteListener(this, task -> {
                        if (task.isSuccessful()) {
                            // Sign in success, update UI with the signed-in user's information
                            FirebaseUser user = mAuth.getCurrentUser();
                            // Update UI
                        } else {
                            // If sign in fails, display a message to the user.
                            Toast.makeText(getApplicationContext(), "Authentication failed.",
                                    Toast.LENGTH_SHORT).show();
                        }
                    });

Implement Sign-in:


            mAuth.signInWithEmailAndPassword(email, password)
                    .addOnCompleteListener(this, task -> {
                        if (task.isSuccessful()) {
                            // Sign in success, update UI with the signed-in user's information
                            FirebaseUser user = mAuth.getCurrentUser();
                            // Update UI
                        } else {
                            // If sign in fails, display a message to the user.
                            Toast.makeText(getApplicationContext(), "Authentication failed.",
                                    Toast.LENGTH_SHORT).show();
                        }
                    });
