I just created an application, and I managed to get the phone contacts when I press a button and retrieve the number of the selected one.
My problem is that I only see phone contacts and not SIM contacts.
My code is:
@Override
    public void onActivityResult(int reqCode, int resultCode, Intent data) {
        super.onActivityResult(reqCode, resultCode, data);
        if (resultCode!=0){
             Uri uri = data.getData();
             Cursor cursor=this.getContentResolver().query(uri, null, null, null, null);
                while (cursor.moveToNext()) { 
                String contactId = cursor.getString(cursor.getColumnIndex( 
                  ContactsContract.Contacts._ID)); 
                String hasPhone = cursor.getString(cursor.getColumnIndex( 
                  ContactsContract.Contacts.HAS_PHONE_NUMBER)); 
                if ((Integer.parseInt(cursor.getString( cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0)) { 
                             // You know have the number so now query it like this
             Cursor phones = getContentResolver().query( 
               ContactsContract.CommonDataKinds.Phone.CONTENT_URI, 
               null, 
               ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId, 
                   null, null); 
                 while (phones.moveToNext()) { 
                  phoneNumber = phones.getString( 
                   phones.getColumnIndex( 
                      ContactsContract.CommonDataKinds.Phone.NUMBER));
                 } 
                 phonenumber.setText(phoneNumber);
                 phones.close(); 
                } 
              }
        }
    }
And something i cannot understand.
Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI); startActivity(intent);
Shows all contacts but i cannot pick one and for result
Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI); startActivityForResult(intent, 1);
Shows only contacts in phone why is that ?
