What is the Facebook SDK for Android?
The Facebook SDK for Android is a collection of tools and libraries that enable you to add Facebook features to your Android app. Some of the features that you can implement using the Facebook SDK for Android are:
Login with Facebook: Allows users to log in to your app using their Facebook account and access their profile information.
Share with Facebook: Allows users to share content from your app to Facebook, such as photos, videos, links, or messages.
App Events: Allows you to track and measure user actions and conversions in your app, such as app installs, purchases, or custom events.
Graph API: Allows you to access data from Facebook's social graph, such as user profiles, friends, pages, groups, events, or posts.
App Links: Allows you to link your app content with other apps or websites, such as opening a specific page or product in your app from a web link.
Audience Network: Allows you to monetize your app by displaying ads from Facebook's advertisers.
Account Kit: Allows users to log in to your app using their phone number or email address without a password.
Why do you need to download facebook.jar?
To use the Facebook SDK for Android in your app, you need to download facebook.jar, which is the core library that contains the classes and resources that enable you to initialize the SDK and use its features. Without facebook.jar, you cannot use any of the features of the SDK in your app.
How to download facebook.jar
Using Maven (preferred method)
The preferred method of downloading facebook.jar is using Maven, which is a build automation tool that manages dependencies and libraries for your project. To use Maven, you need to add some code to your module-level build.gradle file before dependencies:
repositories // You can also use jcenter if you prefer mavenCentral()
Then, you need to add the compile dependency with the latest version of the Facebook SDK in the build.gradle file:
dependencies // Facebook SDK Core only (Analytics) compile 'com.facebook.android:facebook-core:5.+' // Facebook Login only compile 'com.facebook.android:facebook-login:5.+' // Facebook Share only compile 'com.facebook.android:facebook-share:5.+' - Facebook Places only compile 'com.facebook.android:facebook-places:5.+' // Facebook Messenger only compile 'com.facebook.android:facebook-messenger:5.+' // Facebook App Links only compile 'com.facebook.android:facebook-applinks:5.+' // Facebook Android SDK (everything) compile 'com.facebook.android:facebook-android-sdk:5.+'
After adding the dependencies, you need to sync your project with Gradle files, which will automatically download facebook.jar and other required libraries to your project.
Using direct downloads
If you cannot use Maven, you can also download facebook.jar directly from the Facebook developer website. However, this method is not recommended, as it may cause compatibility issues and require manual updates. To use this method, you need to follow these steps:
Downloading the entire Facebook SDK for Android
Go to the and click on the "Download SDK" button. You will be prompted to log in with your Facebook account and accept the terms and conditions. Then, you will be able to download a zip file that contains the entire Facebook SDK for Android.

Extracting the facebook.jar file from the zip archive
After downloading the zip file, you need to extract it to a folder of your choice. Inside the folder, you will find a subfolder called "facebook". This subfolder contains the facebook.jar file that you need for your project.
Adding the facebook.jar file to your project's libs folder
Once you have extracted the facebook.jar file, you need to copy it to your project's libs folder, which is located under app/src/main in your project directory. If the libs folder does not exist, you need to create it first. Then, you need to add the facebook.jar file as a library dependency in your module-level build.gradle file:
dependencies compile files('libs/facebook.jar')

Initializing the Facebook SDK
Before you can use any of the features of the Facebook SDK in your app, you need to initialize the SDK. To do this, you need to follow these steps:
Create a Facebook app ID for your app on the . You will need this app ID to configure your app with the SDK.
Add your app ID and other metadata to your AndroidManifest.xml file, as shown below:
Create a strings.xml file under app/src/main/res/values and add your app ID as a string resource, as shown below:
YOUR_APP_ID
Create a class that extends Application and override its onCreate() method to initialize the SDK with your app ID, as shown below:
public class MyApplication extends Application @Override public void onCreate() super.onCreate(); // Initialize the SDK with your app ID FacebookSdk.sdkInitialize(getApplicationContext());
Add your application class name to the AndroidManifest.xml file under the application tag, as shown below:
...
Implementing Facebook features in your app
After initializing the SDK, you can start using the Facebook features in your app. Depending on the features you want to use, you may need to add some additional code and permissions to your app. Here are some examples of how to implement some of the most common features:
Login with Facebook
To allow users to log in to your app with their Facebook account, you need to add a LoginButton to your layout file, as shown below:
You also need to add a callback manager to handle the login result in your activity class, as shown below:
public class MainActivity extends AppCompatActivity // Create a callback manager to handle login responses private CallbackManager callbackManager; @Override protected void onCreate(Bundle savedInstanceState) super.onCreate(savedInstanceState); // Initialize the callback manager callbackManager = CallbackManager.Factory.create(); setContentView(R.layout.activity_main); // Get the login button from the layout LoginButton loginButton = (LoginButton) findViewById(R.id.login_button); // Set the permissions you want to request from the user loginButton.setPermissions(Arrays.asList("email", "public_profile")); // Register a callback to handle the login result loginButton.registerCallback(callbackManager, new FacebookCallback() @Override public void onSuccess(LoginResult loginResult) // Login success, do something with the login result Log.d("Facebook", "Login success: " + loginResult); @Override public void onCancel() // Login canceled, do something else Log.d("Facebook", "Login canceled"); @Override public void onError(FacebookException error) // Login error, handle the error Log.e("Facebook", "Login error: " + error); ); @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) super.onActivityResult(requestCode, resultCode, data); // Pass the activity result to the callback manager callbackManager.onActivityResult(requestCode, resultCode, data);
You also need to add the following permission to your AndroidManifest.xml file:
Share with Facebook
To allow users to share content from your app to Facebook, you need to use the ShareDialog or the ShareButton. The ShareDialog allows you to show a dialog with various sharing options, such as sharing a link, a photo, a video, or a message. The ShareButton allows you to show a button that triggers the ShareDialog when clicked. Here is an example of how to use the ShareDialog in your activity class:
public class MainActivity extends AppCompatActivity // Create a share dialog private ShareDialog shareDialog; @Override protected void onCreate(Bundle savedInstanceState) super.onCreate(savedInstanceState); // Initialize the share dialog shareDialog = new ShareDialog(this); setContentView(R.layout.activity_main); // Create a share button and set its onClickListener Button shareButton = (Button) findViewById(R.id.share_button); shareButton.setOnClickListener(new View.OnClickListener() @Override public void onClick(View v) // Create a share content object with the content you want to share ShareLinkContent content = new ShareLinkContent.Builder() .setContentUrl(Uri.parse(" .setQuote("This is an example of sharing a link with Facebook") .build(); // Show the share dialog with the content shareDialog.show(content); );
You also need to add the following activity tag to your AndroidManifest.xml file under the application tag:
App Events
To track and measure user actions and conversions in your app, you need to use App Events. App Events allow you to log events that occur in your app, such as app installs, purchases, or custom events. You can then view and analyze these events on the Facebook Analytics dashboard. Here is an example of how to log an app install event in your application class:
public class MyApplication extends Application @Override public void onCreate() super .onCreate(); // Initialize the SDK with your app ID FacebookSdk.sdkInitialize(getApplicationContext()); // Log an app install event AppEventsLogger.activateApp(this);
You can also log other events in your activity classes, such as purchases or custom events. Here is an example of how to log a purchase event in your activity class:
public class MainActivity extends AppCompatActivity @Override protected void onCreate(Bundle savedInstanceState) super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); // Get the app events logger instance AppEventsLogger logger = AppEventsLogger.newLogger(this); // Log a purchase event with the amount, currency, and parameters logger.logPurchase(BigDecimal.valueOf(4.99), Currency.getInstance("USD"), null);
You can also create and log custom events with your own event name and parameters. Here is an example of how to log a custom event in your activity class:
public class MainActivity extends AppCompatActivity @Override protected void onCreate(Bundle savedInstanceState) super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); // Get the app events logger instance AppEventsLogger logger = AppEventsLogger.newLogger(this); // Create a bundle with the parameters for the custom event Bundle params = new Bundle(); params.putString("level", "5"); params.putInt("score", 100); // Log a custom event with the event name and parameters logger.logEvent("game_completed", params);
