Here I am accessing name and phone number from mobile and uploading to server. I am not facing any problem in this. I have made some modifications to access email also. But I am not able to fetch the email. In place of email it is displaying phone number. I have used System.out.print to check the details. Here is my code.
DisplayContact
public class DisplayContact extends Activity implements OnItemClickListener{
//ArrayList to store name and phone number
List<String> name1 = new ArrayList<String>();
List<String> phno1 = new ArrayList<String>();
List<String> email1 = new ArrayList<String>();
MyAdapter ma ;
Button select;
private String vault;
public static final String kvault = "vault_no";
public static final String kname = "name";
public static final String kphone = "phone";
public static final String kemail = "email";
public static final String kcontacts = "contacts";
public static final String SHARED_PREF_NAME = "myloginapp";

super.onCreate(savedInstanceState);

vault = sharedPreferences.getString(ProfileLogin.EMAIL_SHARED_PREF,"Not Available");
getAllContacts(this.getContentResolver());
ListView lv= (ListView) findViewById(R.id.lv);
ma = new MyAdapter();
lv.setAdapter(ma);
lv.setOnItemClickListener(this);
lv.setItemsCanFocus(false);
lv.setTextFilterEnabled(true);
// adding

select.setOnClickListener(new View.OnClickListener()

I think I am missing something in this part it seems.
phones = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null,null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME+" ASC");
Try this :--
private String retriveContactEmail(Uri uriContact) {
String useremail = null;
// getting contacts ID
Cursor cursorID = getActivity().getContentResolver().query(uriContact, new String[]{ContactsContract.Contacts._ID}, null, null, null);
if (cursorID.moveToFirst()) {
contactID = cursorID.getString(cursorID.getColumnIndex(ContactsContract.Contacts._ID));
}
cursorID.close();
// get email and type
Cursor emailCur = getActivity().getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, null, ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?", new String[]{contactID}, null);
while (emailCur.moveToNext()) {
// This would allow you get several email addresses
// if the email addresses were stored in an array
String email = emailCur.getString(emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
String emailType = emailCur.getString(emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.TYPE));
useremail = email;
}
emailCur.close();
return useremail;
}
