Main Activity how can retrieve data...

 public class AddressBook extends Activity
    {
    ListView lv1;
    String[] row,row1;
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
//how can retrieve contact details ...................................................

Try with the following approach

Try to create a bean where you will store details and create an arraylist of that bean class

AddressBook.java

import java.util.ArrayList;
import java.util.Iterator;

import android.app.Activity;
import android.content.ContentResolver;
import android.content.Context;
import android.database.Cursor;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.os.Bundle;
import android.provider.BaseColumns;
import android.provider.ContactsContract;
import android.provider.ContactsContract.CommonDataKinds.Email;
import android.provider.ContactsContract.CommonDataKinds.Phone;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.Button;
import android.widget.LinearLayout;
import android.widget.ListView;

public class AddressBook extends Activity
{
ListView lv1;
String[] row,row1;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

        ArrayList<ContactEmailBean> emailContacts1 = getContactEmails(this);
        ArrayList<ContactNumberBean> phoneContacts1 = getContactNumbers(this);


    }



    public ArrayList<ContactNumberBean> getContactNumbers(Context context) {
        String contactNumber = null;
        int contactNumberType = Phone.TYPE_MOBILE;
        String nameOfContact = null;
        ArrayList<ContactNumberBean> phoneContacts = new ArrayList<ContactNumberBean>();
            ContentResolver cr = context.getContentResolver();
            Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null,
                    null, null, null);
            if (cur.getCount() > 0) {
                while (cur.moveToNext()) {
                    String id = cur.getString(cur
                            .getColumnIndex(BaseColumns._ID));

here Class B does not extends Activity. But write the following method to gwt contacts and email id in class B

                null, null, null);
        if (cur.getCount() > 0) {
            while (cur.moveToNext()) {
                String id = cur.getString(cur
                        .getColumnIndex(BaseColumns._ID));
                nameOfContact = cur
                        .getString(cur
                                .getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));

                if (Integer
                        .parseInt(cur.getString(cur

}

Write two bean class

EmailBean

public class ContactEmailBean {
        String emailType = null;
        String nameOfContact = null;

        String emailIdOfContact = null;

        public ContactEmailBean(String nameOfContact, String emailIdOfContact,
                int emailType) {
            switch (emailType) {
            case Email.TYPE_HOME:
                this.emailType = "HOME";
                // do something with the Home number here...
                break;
            case Email.TYPE_MOBILE:
                this.emailType = "MOBILE";
                // do something with the Mobile number here...
                break;
            case Email.TYPE_WORK:
                this.emailType = "WORK";
                // do something with the Work number here...
                break;

            default:
                this.emailType = "OTHER";
                break;
            }
            this.nameOfContact = nameOfContact;
            this.emailIdOfContact = emailIdOfContact;

        }

        public String getNameOfContact() {
            return this.nameOfContact;
        }

        public String getEmailType() {
            return this.emailType;
        }

        public String getEmailIdOfContact() {
            return this.emailIdOfContact;
        }
    }

ContactNumberBean

public class ContactNumberBean {
        String phoneNumberType = null;
        String nameOfContact = null;
        String contactNumber = null;

        public ContactNumberBean(String nameOfContact, String contactNumber,
                int contactNumberType) {
            switch (contactNumberType) {
            case Phone.TYPE_HOME:
                this.phoneNumberType = "HOME";
                // do something with the Home number here...
                break;
            case Phone.TYPE_MOBILE:
                this.phoneNumberType = "MOBILE";
                // do something with the Mobile number here...
                break;
            case Phone.TYPE_WORK:
                this.phoneNumberType = "WORK";
                // do something with the Work number here...
                break;
            case Phone.TYPE_WORK_MOBILE:
                this.phoneNumberType = "WORK";
                break;

            case Phone.TYPE_FAX_HOME:
                this.phoneNumberType = "FAX";
                break;
            default:
                this.phoneNumberType = "OTHER";
                break;
            }
            this.nameOfContact = nameOfContact;
            this.contactNumber = contactNumber;

        }

        public String getNameOfContact() {
            return this.nameOfContact;
        }

        public String getPhoneNumberType() {
            return this.phoneNumberType;
        }

        public String getContactNumber() {
            return this.contactNumber;
        }

}
