This gives all the phone numbers from a picked contact in a hassle free manner

Start the Contact Activity,

Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);

startActivityForResult(intent, PICK_CONTACT);

Now use the following to get all the data,

@Override
public void onActivityResult(int reqCode, int resultCode, Intent data){
    super.onActivityResult(reqCode, resultCode, data);

    switch(reqCode){
       case (PICK_CONTACT):
         if (resultCode == Activity.RESULT_OK){
             Uri contactData = data.getData();
             Cursor c = managedQuery(contactData, null, null, null, null);
             ContentResolver cr = getContentResolver();

             if (c.moveToFirst())
             {
                 try
                 {
                     String id = c.getString(c.getColumnIndex(ContactsContract.Contacts._ID));
                     String name = c.getString(c.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME));
                     if (Integer.parseInt(c.getString(c.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) 
                     {
                        Cursor pCur = cr.query(
                        ContactsContract.CommonDataKinds.Phone.CONTENT_URI, 
                        null, 
                        ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?", 
                        new String[]{id}, null);
                        String phone = "";
                        while (pCur.moveToNext()) 
                        {
                            try
                            {
                                phone = phone + pCur.getString(pCur.getColumnIndex(ContactsContract.Contacts.Data.DATA1)) + ",";
                            }
                            catch(Exception ex)
                            {

                            }
                        } 
                        pCur.close();
                        if(phone.length() > 0)
                        {
                            phone = phone.substring(0,phone.length()-1);
                        }
                        txtPhone.setText(phone);
                     }
                     txtName.setText(name); 
                 }
                 catch(Exception ex)
                 {
                     Toast.makeText(AddToInnerCircle.this, "No name selected", Toast.LENGTH_SHORT).show();
                 }
             }
         }
    }
