Login With Facebook Android Studio using Facebook SDK 4

May 4, 2015 by Belal Khan 111 Comments

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

    repositories {
        mavenCentral()
    }

repositories {

mavenCentral()

}

Now add a new dependency for Facebook SDK
Inside dependencies add this line

compile 'com.facebook.android:facebook-android-sdk:4.0.0'

1	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.

Creating Facebook App ID

Click create app id.
You will be redirected to your apps dashboard.

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.

Adding a Platform for your App

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

<string name="app_id">YOUR APP ID</string>

1	<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

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

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

Add a this meta-data code inside your application

    <meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/app_id"/>

1	<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

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) {

        }
    }
}

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

    <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>

<application

android:name=".MyApplication"

android:allowBackup="true"

android:icon="@mipmap/ic_launcher"

android:label="@string/app_name"

android:theme="@style/AppTheme" >

</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.

      <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" />

<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

<?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>

<?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" >

<activity

android:name=".MainActivity"

android:label="@string/app_name" >

<intent-filter>

</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.

<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>

<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.

package net.simplifiedcoding.androidlogin;

import android.content.Intent;
import android.support.v4.app.Fragment;

        };

        accessTokenTracker.startTracking();
        profileTracker.startTracking();
    }

    @Override

    private void displayMessage(Profile profile){

  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();}

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?

  List permissions = new ArrayList();
  permissions.add(“email”);
  
  Add all the permissions you need and then
  loginButton.setReadPermissions(permissions);
  
  For more information you can check the sdk docs from here https://developers.facebook.com/docs/facebook-login/android/permissions

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.

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
