Step 1 Download Facebook SDK

For our Facebook login Android tutorial, we first need to Download Facebook SDK for Android.

After you are done downloading, please import it in Android Studio.


Step 2 Create New Project in Android Studio

If you are new to Android Studio and don't know how to create a new project then you should checkout our other blog:


Step 3 Link Facebook SDK

Link downloaded Facebook SDK as library project with demo application:

Add Module Dependancy For Facebook SDK

If you are not aware about how to add module dependency in Android, please refere the following blog.


Step 4 Get Key Hash Value

Now you need to Get Key Hash Value for your machine. The key hash value is used by Facebook as security check for login. To get key hash value of your machine, write following code in onCreate() method of

try {
    PackageInfo info = getPackageManager().getPackageInfo(
    getPackageName(), PackageManager.GET_SIGNATURES);
    for (Signature signature : info.signatures) {
        MessageDigest md = MessageDigest.getInstance("SHA");
        Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
} catch (NameNotFoundException e) {
} catch (NoSuchAlgorithmException e) {

Step 5 Create Facebook App

We need to create facebook app in order to get Facebook App ID. To do so, create an application on FB developer site.

Go to

After login, click on Add a New App.

Type your application name. 


Choose category and click on Confirm


Once application is created, go to application dashboard and note down App ID


To register package and activity, go to Settings from left menu and click on Add Platform and select Android


Register your application package name and activity which uses Facebook sharing. And add key hash values explained in Step 4. 



Step 6 Add App ID

Add App ID in strings.xml file of your project. put your app id in place of "your app_id".

<string name="app_id">your app_id</string>

Step 7 Changes in Manifest file

Open AndroidManifest.xml of project. Make following changes:

Add Internet Permission:

<uses-permission android:name="android.permission.INTERNET">

Add meta data in tag:


Add New Activity:

<activity android:name="com.facebook.LoginActivity">

Step 8 Facebook Login

To integrate Facebook Login in Android application, call Session.openActiveSession() method of Session class in

This method of Session class is used for Facebook login.

This method takes 3 arguments:

1. Activity 

2. Boolean variable to indicate Login UI to be used or not

3. And call back to be called when status of session is changed.

Session.openActiveSession(this, true, new Session.StatusCallback() {
    // callback when session changes state
    public void call(Session session, SessionState state, Exception exception) {

Step 9 Successful Login

Now since we are done with the Facebook login integration in Android, we need to Handle onActivityResult() in

public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Session.getActiveSession().onActivityResult(this, requestCode,
resultCode, data);

Step 10 Fetching User Data

In our Facebook Integration in Android Studio example, to get user info, following permissions are required:

  • strong > basic_info
  • email

Once Facebook login is completed, call() method of StatusCallback() is called.

Inside call() method, newMeRequest() method would be executed.

After request execution, callback will be called and returns object of GraphUser.

This request will only return friends from friend list who have used (via Facebook Login) the app making the request.

Request.newMyFriendsRequest(session, new GraphUserListCallback() {
    public void onCompleted(List users, Response response) {

To get friends list following permission is required:

  • user_friends


The following permission is granted by Facebook:

  • public_profile
  • email
  • user_friends

If you need more permissions other than mentioned above, you'll need to submit the app to Facebook for review.
