android - I'm having trouble loading email addresses from the Phone's contacts -

i trying generate list of emails phone's contacts have having trouble getting emails. can names , phone numbers not emails. arraylist sizes both 0 @ end of loop. can spot doing wrong, or tell me how emails differ phone numbers, names , other information?

    contentresolver cr = getcontentresolver();      cursor emailcur = cr.query(             contactscontract.commondatakinds.email.content_uri, null,             contactscontract.commondatakinds.email.contact_id + " = ?",             null, null);      arraylist<string> emails = new arraylist<string>();     arraylist<string> emailtypes = new arraylist<string>();      while (emailcur.movetonext()) {         // allow several email addresses         // if email addresses stored in array         string email = emailcur                 .getstring(emailcur                         .getcolumnindex(contactscontract.commondatakinds.email.data));         string emailtype = emailcur                 .getstring(emailcur                         .getcolumnindex(contactscontract.commondatakinds.email.type));          emails.add(email);         emailtypes.add(emailtype);      }      emailcur.close();      log.i("emails count", integer.tostring(emails.size()));     (int = 0; < emails.size(); i++) {         log.i("emails " + i, emails.get(i));     }      log.i("emailtypes count", integer.tostring(emailtypes.size()));     (int = 0; < emailtypes.size(); i++) {         log.i("emailtypes " + i, emailtypes.get(i));     } 

use code email device.

contentresolver cr = getcontentresolver();                  cur = cr.query(contactscontract.contacts.content_uri, null,null, null, null);                  emailindex=0;                 if (cur.getcount() > 0)                  {                      while (cur.movetonext())                      {                         string id = cur.getstring(cur.getcolumnindex(contactscontract.contacts._id));                         name = cur.getstring(cur.getcolumnindex(contactscontract.contacts.display_name));                          cursor emails = getcontentresolver().query(contactscontract.commondatakinds.email.content_uri,null,                                 contactscontract.commondatakinds.email.contact_id+ " = " + id, null, null);                         while (emails.movetonext())                          {                             // allow several email addresses                             string emailaddress = emails.getstring(emails.getcolumnindex(contactscontract.commondatakinds.email.data));                             log.v(name+"==>", emailaddress);                          }                         emails.close();                              }                     cur.close();
