Hello friends, welcome to our new tutorial. In this tutorial we will create a login with facebook android app using android studio and facebook sdk 4.0. So lets begin.
Creating Android Project
- Open Android Studio and Click on File-> New ->New Project
- Give your application a name (in my case it is AndroidLogin) and a package (mine is net.simplifiedcoding)
- Select Phone or Tablet
- Select Blank Activity with Fragment.
- Leave the rest things as it is and finish.
- Now once our project is ready we need to configure a lot of things so lets begin.
Prerequisites for creating Login with Facebook Android App
- Facebook app configured and linked to our android app
- Facebook SDK
- Facebook App ID
- Android Key Hash
- Facebook Activity
Lets start with creating Facebook App
Configuring Facebook SDK to Android Studio
- Go to your gradle scripts -> build.gradle(Module:app)
- Add the following code
1 2 3 4 5 | repositories { mavenCentral() } |
- Now add a new dependency for Facebook SDK
- Inside dependencies add this line
1 2 3 | compile 'com.facebook.android:facebook-android-sdk:4.0.0' |
- It will download facebook sdk and will take some time. It can take long time if you have a slow internet connection. So mean while lets create our facebook app.
Creating Facebook App
- Go to https://developers.facebook.com/. If you have not registered yourself as a developer yet then facebook will ask you to register as a developer. Simply register as a developer. (Congrats you are now a developer :P)
- From the top navigation menu hover over my apps.
- Then click add a new app.
- You will asked to select a platform, click on android.
- On the new page you can select quick start or you can select skip and create app id from the upper right corner.
- Click on skip and create app id.
- Give a display name and a namespace for your app as shown in the image below.
- Click create app id.
- You will be redirected to your apps dashboard.
- Here you can get your app id. Copy the app id it will be used further. (I have made my app id hidden because i cant let you see it for security reasons)
- Now from the left click on settings.
- Click on add a platform and select android.
- Enter your package name and class name of your main activity and click on save changes
- The last thing you need is your App Key Hashes.
Generating Key Hashes for your Login With Facebook Android App
- Go to android studio.
- On your project open your strings.xml file (res->values->strings.xml)
- Add the below code
1 2 3 | <string name="app_id">YOUR APP ID</string> |
- Replace your actual app id with your app id.
- Now go to your AndroidManifest.xml
- First add internet permission using the following code
1 2 3 | <uses-permission android:name="android.permission.INTERNET"/> |
- Add a this meta-data code inside your application
1 2 3 | <meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/app_id"/> |
- This is containing our app id which we defined inside strings.xml.
- Now create a new class in your package and name it MyApplication (name doesn’t matter you can name it anything)
- Copy the following code
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 | package net.simplifiedcoding.androidlogin; import android.app.Application; import android.content.pm.PackageInfo; import android.content.pm.PackageManager; import android.content.pm.Signature; import android.util.Base64; import android.util.Log; import java.security.MessageDigest; import java.security.NoSuchAlgorithmException; /** * Created by Belal on 5/3/2015. */ public class MyApplication extends Application { @Override public void onCreate() { super.onCreate(); printHashKey(); } public void printHashKey(){ // Add code to print out the key hash try { PackageInfo info = getPackageManager().getPackageInfo( "net.simplifiedcoding.androidlogin", PackageManager.GET_SIGNATURES); for (Signature signature : info.signatures) { MessageDigest md = MessageDigest.getInstance("SHA"); md.update(signature.toByteArray()); Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT)); } } catch (PackageManager.NameNotFoundException e) { } catch (NoSuchAlgorithmException e) { } } } |
- Make sure in the above code your provide your application’s package name.
- The above class will print the KeyHash in the logcat. But we still need to define this class inside your AndroidManifest.
- Go to AndroidManifest.xml again and Inside application opening tag define your class as shown below
1 2 3 4 5 6 7 8 9 10 11 12 13 | <application android:name=".MyApplication" android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/app_id"/> . . . </application> |
- Now execute your app and you will get your keyhash in your logcat.
- Copy the keyhash and enter that to your app settings in facebook and click save.
Creating your Login With Facebook Android App
- For facebook login Facebook SDK provides an activity that will open while login. You only need to add that activity to your manifest file.
- Add the facebook activity using the following code.
1 2 3 4 5 6 7 | <activity android:name="com.facebook.FacebookActivity" android:configChanges= "keyboard|keyboardHidden|screenLayout|screenSize|orientation" android:theme="@android:style/Theme.Translucent.NoTitleBar" android:label="@string/app_name" /> |
- So your final AndroidManifest.xml would be like
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 | <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="net.simplifiedcoding.androidlogin" > <uses-permission android:name="android.permission.INTERNET"/> <application android:name=".MyApplication" android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/app_id"/> <activity android:name=".MainActivity" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name="com.facebook.FacebookActivity" android:configChanges= "keyboard|keyboardHidden|screenLayout|screenSize|orientation" android:theme="@android:style/Theme.Translucent.NoTitleBar" android:label="@string/app_name" /> </application> </manifest> |
- Now come to your fragment layout and create a TextView and a Facebook Login Button. The button is provided by facebook sdk. You can use the below code.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 | <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:orientation="vertical" android:paddingTop="@dimen/activity_vertical_margin" android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivityFragment"> <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="New Text" android:id="@+id/textView" android:layout_centerHorizontal="true"/> <com.facebook.login.widget.LoginButton android:id="@+id/login_button" android:layout_width="fill_parent" android:layout_height="wrap_content" /> </LinearLayout> |
- We will show the user name in the textview after successful login.
- Go to your MainFragment.java and copy the following code.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 | package net.simplifiedcoding.androidlogin; import android.content.Intent; import android.support.v4.app.Fragment; import android.os.Bundle; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.TextView; import com.facebook.AccessToken; import com.facebook.AccessTokenTracker; import com.facebook.CallbackManager; import com.facebook.FacebookCallback; import com.facebook.FacebookException; import com.facebook.FacebookSdk; import com.facebook.Profile; import com.facebook.ProfileTracker; import com.facebook.login.LoginResult; import com.facebook.login.widget.LoginButton; /** * A placeholder fragment containing a simple view. */ public class MainFragment extends Fragment { private CallbackManager callbackManager; private TextView textView; private AccessTokenTracker accessTokenTracker; private ProfileTracker profileTracker; private FacebookCallback<LoginResult> callback = new FacebookCallback<LoginResult>() { @Override public void onSuccess(LoginResult loginResult) { AccessToken accessToken = loginResult.getAccessToken(); Profile profile = Profile.getCurrentProfile(); displayMessage(profile); } @Override public void onCancel() { } @Override public void onError(FacebookException e) { } }; public MainFragment() { } @Override public void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); FacebookSdk.sdkInitialize(getActivity().getApplicationContext()); callbackManager = CallbackManager.Factory.create(); accessTokenTracker= new AccessTokenTracker() { @Override protected void onCurrentAccessTokenChanged(AccessToken oldToken, AccessToken newToken) { } }; profileTracker = new ProfileTracker() { @Override protected void onCurrentProfileChanged(Profile oldProfile, Profile newProfile) { displayMessage(newProfile); } }; accessTokenTracker.startTracking(); profileTracker.startTracking(); } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { return inflater.inflate(R.layout.fragment_main, container, false); } @Override public void onViewCreated(View view, Bundle savedInstanceState) { super.onViewCreated(view, savedInstanceState); LoginButton loginButton = (LoginButton) view.findViewById(R.id.login_button); textView = (TextView) view.findViewById(R.id.textView); loginButton.setReadPermissions("user_friends"); loginButton.setFragment(this); loginButton.registerCallback(callbackManager, callback); } @Override public void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); callbackManager.onActivityResult(requestCode, resultCode, data); } private void displayMessage(Profile profile){ if(profile != null){ textView.setText(profile.getName()); } } @Override public void onStop() { super.onStop(); accessTokenTracker.stopTracking(); profileTracker.stopTracking(); } @Override public void onResume() { super.onResume(); Profile profile = Profile.getCurrentProfile(); displayMessage(profile); } } |

When i create a Blank Activity with Fragment it creates me an activity that extends from ActionBarActivity and then creates a class that extends from Fragment, how can i execute my MainFragment from an class that extends form ActionBarActivity.
I am not getting what you want to ask? Tell me your actual requirement.. or you can check details about fragments from here – > http://developer.android.com/training/basics/fragments/creating.html
hey bilal khan …can you make an tutorial on sharing photos videos or status from android app to facebook automatically…
from your activity you can go to mainfragment, after setcontentview paste this
if (savedInstanceState == null){
getSupportFragmentManager().beginTransaction()
.add(android.R.id.content, new MainFragment ()).commit();}
Your tutorial is great and helped me a lot but I want to create the login button on a popup window, how should I do that? and how can I hide the login button when the user has already loged in? and will you do some tutorials on facebook sharing and like button too?
Ok stay tuned I will try to help you with some more tutorials ASAP 🙂
Is there a way to use the FB SDK log in button without using a fragment? Can I just put it straight on the MainActivity? If so, how do I do this?
Yeah you can obviously do that
How can i integrate this code in my main activity without creating a fragment class??
//refer the link
http://www.androidwarriors.com/2016/02/facebook-integration-in-android-studio.html

Hi, great tutorial but i seem to have an error through your code. when i run inspect code in android studio it comes up with an error such as…
Location
class anonymous in FacebookCallback callback (mobliedevelopment.terrelsimeongordon.hwl_fb.MainFragment)
Problem synopsis
Variable ‘accessToken’ at line 38 is never used
i downloaded the source code yet the same error comes up
this is the code that android is complaining about?
private FacebookCallback callback = new FacebookCallback() {
@Override
public void onSuccess(LoginResult loginResult) {
AccessToken accessToken = loginResult.getAccessToken();
Profile profile = Profile.getCurrentProfile();
displayMessage(profile);
}
do you have any clue why it is not working and why it can not find accessToken? grateful if you could help answer this 1 million dollar question 🙂
Hi sorry about that i just found the issue 🙂
just wondering if its possible to extend just an activity instead of an ActionBarActivity for the MainActivity? if so how would you i go about altering this code to that requirement?

Hi,
I am able to integrate facebook login into my app successfully by follwing your post. The actual req of my app is to trigger facebook status at the end of every month. When i try to login after two months login dialog does not open up. It throws a FacebookAuthorizationException. Can you please help me in figuring it out.
Note: I believe due to access token expiry facebook login dialog does not open. You can check it
Thanks.
After clicking the Facebook login button, I am getting an error saying you are not logged in. please log in and try again…how to login?

Hi, that was an really awesome tutorial, I run the app, go the output. But I tried to reopen means its shows the HashKey error. Please guide me
Check you have generated the HashKey correctly or not?
How can i dentify the keyhash on the logcat ? :/
follow the post carefully.. and after writing the keyhash part run you app and check the logcat for keyhash
Hi Belal u have done a good job. I tried many totorials but got disappointed. i used your tutorial in my case it is working, but if i try to login second time it shows the message “This app has no Android key hashes configured. pls configure hash key. but i configured key hash succesfully still get error msg from second time login.. pls help me..

Hi Bilal,
Thank you for this great tutorial. I just want to share one solution for those who’s getting error of hash key. When you run your programme at first time it’s successfully login but second time it give error of hash key. The solution is the key which is shown in device as a error is your correct hash key so save this key on facebook app setting and the error is gone. thanks
