Linkedin Android SDK (Unofficial)

LinkedinSDK allows you to get linkedin access token inside your Android application.

Installation

To install the SDK:

Add it in your root build.gradle at the end of repositories:

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

Add the dependency:

implementation 'com.github.ovidos:linkedin-android-sdk:0.1.9'

For login flow to work, LinkedinSignInActivity needs to be added to AndroidManifest.xml:

<activity android:name="com.omralcorut.linkedinsignin.ui.LinkedinSignInActivity"/>

Also, you need to add internet permission to AndroidManifest.xml:

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

Authentication

Linkedin SDK is allows you to authenticate with OAuth2 authentication. This means that, you are allowed to manage other people's account that are authorized with your application.

Getting Started

First of all you need to retrieve Client ID, Client Secret and Redirect Uri from Linkedin. To add Client ID, Client Secret and Redirect Uri into your application:

1. Open your Application Class and add the following

// Kotlin

Linkedin.initialize(context = applicationContext,
        	clientId = "LINKEDIN_CLIENT_ID",
        	clientSecret = "LINKEDIN_CLIENT_SECRET",
        	redirectUri = "LINKEDIN_REDIRECT_URI",
        	state = "RANDOM_STRING",
        	scopes = listOf("r_liteprofile", "r_emailaddress"))

// Java

Linkedin.Companion.initialize(getApplicationContext(),
            	"LINKEDIN_CLIENT_ID",
            	"LINKEDIN_CLIENT_SECRET",
            	"LINKEDIN_REDIRECT_URI",
            	"RANDOM_STRING",
            	Arrays.asList("r_liteprofile", "r_emailaddress"));

"State" is a unique string of your choice designed to protect against CSRF attacks.

2. To authorize a user for your application:

// Kotlin

Linkedin.login(this, object : LinkedinLoginViewResponseListener {
      	override fun linkedinDidLoggedIn(linkedinToken: LinkedinToken) {
          	// Success
      	}
      	override fun linkedinLoginDidFail(error: String) {
          	// Fail
      	}

})

// Java

Linkedin.Companion.login(this, new LinkedinLoginViewResponseListener() {
      	@Override
      	public void linkedinDidLoggedIn(@NotNull LinkedinToken linkedinToken) {
          	// Success
      	}

      	@Override
      	public void linkedinLoginDidFail(@NotNull String error) {
          	// Fail
      	}
});
