How to import google contacts in android (programatically)?

Question

Can any body suggest a way, how to extract contacts from google to the android app?

Thanks!

Below is my code and I'm getting runtime error at line number 57. To be specific it shows exception in AsyncTask.

package com.example.isan.contacts;

import android.os.AsyncTask;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    try {
        this.feedUrl = new URL(url);
    } catch (MalformedURLException e) {
        e.printStackTrace();
    }

    new GetTask().execute();
}





private class GetTask extends AsyncTask<Void, Void, Void> {

        try {

Hi @Isan i am unable to import **import com.google.gdata.data.contacts.ContactFeed;** package. Could you please provide me gradle dependencies needed to fetch contacts ? — Rahul Khurana, Dec 22 '17 at 06:53

Its simple to do. You can try this code.

public static void printAllContacts(ContactsService myService)
    throws ServiceException, IOException {
  // Request the feed
  URL feedUrl = new URL("https://www.google.com/m8/feeds/contacts/liz@gmail.com/full");
  ContactFeed resultFeed = myService.getFeed(feedUrl, ContactFeed.class);
  // Print the results
  System.out.println(resultFeed.getTitle().getPlainText());
  for (int i = 0; i < resultFeed.getEntries().size(); i++) {
    ContactEntry entry = resultFeed.getEntries().get(i);
    System.out.println("\t" + entry.getTitle().getPlainText());

    System.out.println("Email addresses:");
    for (Email email : entry.getEmailAddresses()) {
      System.out.print(" " + email.getAddress());
      if (email.getRel() != null) {
        System.out.print(" rel:" + email.getRel());
      }
      if (email.getLabel() != null) {
        System.out.print(" label:" + email.getLabel());
      }
      if (email.getPrimary()) {
        System.out.print(" (primary) ");
      }
      System.out.print("\n");
    }

    System.out.println("IM addresses:");
    for (Im im : entry.getImAddresses()) {
      System.out.print(" " + im.getAddress());
      if (im.getLabel() != null) {
        System.out.print(" label:" + im.getLabel());
      }
      if (im.getRel() != null) {
        System.out.print(" rel:" + im.getRel());
      }
      if (im.getProtocol() != null) {
        System.out.print(" protocol:" + im.getProtocol());
      }
      if (im.getPrimary()) {
        System.out.print(" (primary) ");
      }
      System.out.print("\n");
    }

    System.out.println("Groups:");
    for (GroupMembershipInfo group : entry.getGroupMembershipInfos()) {
      String groupHref = group.getHref();
      System.out.println("  Id: " + groupHref);
    }

    System.out.println("Extended Properties:");
    for (ExtendedProperty property : entry.getExtendedProperties()) {
      if (property.getValue() != null) {
        System.out.println("  " + property.getName() + "(value) = " +
            property.getValue());
      } else if (property.getXmlBlob() != null) {
        System.out.println("  " + property.getName() + "(xmlBlob)= " +
            property.getXmlBlob().getBlob());
      }
    }

    String photoLink = entry.getContactPhotoLink().getHref();
    System.out.println("Photo Link: " + photoLink);

    if (photoLink.getEtag() != null) {
      System.out.println("Contact Photo's ETag: " + photoLink.getEtag());
    }

    System.out.println("Contact's ETag: " + entry.getEtag());
  }
}

Please have a look at this, for complete guide on how to use the latest Contacts API version 3.

UPDATE

You will need to import these packages.

import com.google.gdata.client.*;
import com.google.gdata.client.contacts.*;
import com.google.gdata.data.*;
import com.google.gdata.data.contacts.*;
import com.google.gdata.data.extensions.*;
import com.google.gdata.util.*;
import java.io.IOException;
import java.net.URL;

There is no way to import your google contacts in your app

But you can access your current contacts in your app.
