Let’s start by creating new android project using Android Studio or you can use any other development environment like eclipse to integrate facebook login in android app/game. Create new project with project name: Facebook Integration Android and minimum API 15: Android 4.0.3.
Open facebook developer site developers.facebook.com . Open MyApp tab and click on the Add a New App. Here you need to fill up app information like name, contact email, app category etc. and click Create App Id button.
In Product Setup (Add Product) page click Facebook Login Get Started button. Enable Client OAuth Login, Web OAuth Login, Embedded Browser OAuth Login, Force Web OAuth Reauthentication and click Save Changes button.
From fb app dashboard click Choose Platform button and select Android.
Now you need to get key hash value for your app. The key hash value is used by facebook as security check for login. To get hash key for your app, follow the following steps:
1. Open command prompt (Terminal)
2. Run the following command:
keytool -exportcert -alias androiddebugkey -keystore C:\Program Files\Java\jdk1.8.0_25\bin\debug.keystore | C:\OpenSSL\bin\openssl sha1 -binary | C:\OpenSSL\bin\openssl base64
Make sure you have installed jdk and OpenSSL in your PC and replace C:\Program Files\Java\jdk1.8.0_25\bin with your jdk bin directory and C:\OpenSSL\bin with your OpenSSL bin directory.
Now you will get hash key something like 2jmj7w0yVb/vlkK/YBwk= copy it.
Go to facebook developer page and select your app. From setting section click Add Platform and choose Android.
Here you need to provide more information about app like app package name, class name, hash key that we have generated above and so on. Add these information, enable Single Sign On and click Save Changes button.
Google Play Package Name: com.viralandroid.facebookandroidintegration
Class Name: com.viralandroid.facebookandroidintegration.MainActivity
Key Hashes: 2jmj7w0yVb/vlkK/YBwk=
From App Review section enable Make Android Integration public.
Open module build.gradle file from android studio. Add repositories {mavenCentral()} and compile 'com.facebook.android:facebook-android-sdk:[4,5)' as dependency and build your project. Build.gradle file will look like below.
