public void onPreAuthCompltBtnClick(View view) {
  Intent intent = new Intent(this, PreAuthCompleteOrCancelActivity.class);
  intent.putExtra(MyPos.INTENT_EXTRA_AMOUNT, amount);
  intent.putExtra(MyPos.INTENT_EXTRA_ORDER_ID, orderId);
  intent.putExtra(MyPos.INTENT_EXTRA_IS_PRE_AUTH_CANCELLATION, false);
  startActivityForResult(intent, MyPos.REQUEST_CODE_PRE_AUTHORIZATION_COMPLETE);

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if( resultCode == RESULT_OK  && requestCode == MyPos.REQUEST_CODE_PRE_AUTHORIZATION_COMPLETE ) {
      int status = data.getIntExtra(MyPos.INTENT_EXTRA_STATUS, MyPos.STATUS_INTERNAL_API_ERROR);

      if( status == MyPos.STATUS_SUCCESS) {
