Step 1: Generate a Key Hash for Your App

Before you can use the Facebook SDK in your Android app, you need to generate a key hash for every device you run this application on until it's in development mode. To do this, follow these steps:

1. Open a terminal or command prompt and navigate to the directory where your keystore file is located.

2. Run the following command to export the certificate: `keytool -exportcert -alias androiddebugkey -keystore 'C:\Path\To\Your\Keystore' | openssl sha1 -binary | openssl base64`

3. Copy and paste the resulting hash key into the Key hashes field in your Facebook app settings.

Step 2: Set Up Single Sign-on (SSO)

To set up SSO, follow these steps:

1. Go to the 'Settings' tab in your Android Studio project.

2. Scroll down to the 'Facebook SDK' section and toggle the switch next to 'Single Sign-on (SSO)' to enable it.

Step 3: Add the Facebook App ID to Your Strings.xml File

To add the Facebook app ID to your strings.xml file, follow these steps:

1. Open your project's strings.xml file in Android Studio.

2. Add the following line to the file: `facebook_app_id='YOUR_APP_ID'`

3. Replace `YOUR_APP_ID` with the actual ID of your Facebook app.

Step 4: Configure Your Project to Use the Facebook SDK

To configure your project to use the Facebook SDK, follow these steps:

1. Open your project's build.gradle file in Android Studio.

2. Add the following dependency to the file: `implementation ':facebook-android-sdk:4.31.0'`

3. Replace `4.31.0` with the latest version of the SDK.

Step 5: Verify That the SDK is Added Successfully

To verify that the SDK is added successfully, follow these steps:

1. Open your project's MainActivity.java file in Android Studio.

2. Add the following import statements to the file: `import com.facebook.FacebookSdk; import com.facebook.appevents.AppEventsLogger;`

3. If there are no errors, the build was successful.

Step 6: Test Your App

To test your app, follow these steps:

1. Run your app on a device or emulator.

2. Log in to Facebook using the login button provided by the SDK.

3. Verify that you are logged in successfully and can access your Facebook profile information.

By following these steps, you should be able to integrate the Facebook SDK into your Android application using Android Studio.
