String strEmailIdOfContact;
int emailType = Email.TYPE_WORK;
String strContactName = null;

if (requestCode == ACTIVITY_PICK_CONTACT)
{
if(resultCode == RESULT_OK)
{
ContentResolver cr = this.getContentResolver();
Cursor cur = managedQuery(data.getData(), null, null, null, null);

if (cur.moveToNext())
{
String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
strContactName = cur.getString(cur.getColumnIndex(People.DISPLAY_NAME));

cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID
+ ” = ?”, new String[] { id }, null);

Cursor emails = cr.query(Email.CONTENT_URI, null,Email.CONTACT_ID + ” = ” + id, null, null);
if (emails.moveToNext()) {

strEmailIdOfContact = emails.getString(emails.getColumnIndex(Email.DATA));

emailType = emails.getInt(emails.getColumnIndex(Phone.TYPE));

if(_objClickedView == btnImportContactsTo)
{
String strGetTo = txtTo.getText().toString();
if(!strGetTo.equals(strEmailIdOfContact))
