Is there any working sample/example available to use Google People API for Android?

Question

I looked into google people API on their official documentation page

https://developers.google.com/people/quickstart/java#step_4_run_the_sample

in spite of following all necessary steps API does not work.

I came across below example on GitHub which is not working as well. https://github.com/Suleiman19/People-API-App

also, I check google example

Credential credential = new AuthorizationCodeInstalledApp(
                flow, new LocalServerReceiver()).authorize("user");

lang.NoClassDefFoundError: Failed resolution of: Ljava/awt/Desktop;

Below code is working. able to access people API

 private static class GetUserInfoTask extends AsyncTask<String, Void, Void> {
    private final Context context;
    private ISignIn iSignIn;
    private HttpTransport httpTransport = new NetHttpTransport();
    private JacksonFactory jsonFactory = new JacksonFactory();
    private String personEmail;
    private String personLastName;
    private String personFirstName;
    private String image;
    private String genderString;
    private String aboutMeLocal;
    private String phoneLocal;
    private long birthdayLocal;

    public GetUserInfoTask(Context context, ISignIn iSignIn) {
        this.context = context;
        this.iSignIn = iSignIn;
    }

    @Override
    protected Void doInBackground(String... params) {
        personEmail = params[0];
        personLastName = params[1];
        personFirstName = params[2];
        image = params[3];


        Person userProfile = null;

        mCredential.setSelectedAccountName(personEmail);

        People service = new People.Builder(httpTransport, jsonFactory, mCredential)
