LinkedIn SDK (Unofficial)

Unofficial SDK for LinkedIn v2 REST APIs

Features

• Sign In with LinkedIn
• Fetch LinkedIn user full profile (id , firstName , lastName , profilePicture , emailAddress)

Getting Started

1- Create app on LinkedIn Developers Console

2- From Auth section get Client ID and Client Secret and do not forget to add “Redirect URL”. The reason being, it will be later used to get callback for identifying the response in native webviews. You can put in any Redirect URL and not necessarily a real one. It can be any value starting with https:// prefix. For example Redirect Url

  https://com.kromer.linkedin.oauth/oauth

3- Add in your root build.gradle at the end of repositories

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

4- Add the dependency in your app build.gradle file

  dependencies {
    implementation 'com.github.kerolloskromer:linkedin-sdk:<latest-version>'
  }

5- Sign in with LinkedIn with single line

  Linkedin.signIn(MainActivity.this, clientId, clientSecret, redirectURL, state);

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

6- Receive sign in response

  @Override
  protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == Linkedin.REQ_CODE_SIGN_IN) {
      if (resultCode == Linkedin.SUCCESS) {
        LinkedinUser linkedinUser = data.getParcelableExtra(Linkedin.USER);
        Toast.makeText(MainActivity.this, linkedinUser.getFirstName(), Toast.LENGTH_SHORT).show();
      } else if (resultCode == Linkedin.FAILURE) {
        int errorType = data.getIntExtra(Linkedin.ERROR_TYPE, 0);
        switch (errorType) {
          case Linkedin.ERROR_NO_INTERNET:
            Toast.makeText(MainActivity.this, "Please check your internet connection",
                Toast.LENGTH_SHORT).show();
            break;
          case Linkedin.ERROR_USER_CANCELLED:
            Toast.makeText(MainActivity.this, "User cancelled authorization", Toast.LENGTH_SHORT)
                .show();
            break;
          case Linkedin.ERROR_OTHER:
            Toast.makeText(MainActivity.this, "Something went wrong", Toast.LENGTH_SHORT).show();
            break;
        }
      }
    }
  }
