question

I am trying to implement TIP flow along with order process. For that I am starting intent "Intents.ACTION_CUSTOMER_ADD_TIP" with start activity for result. But issue is it will start TIP screen to select but same time, instantly it will send result cancelled to parent activity from where customer tip activity is started. After TIP selection and done, parent activity is not receiving any thing. Here below is my code snippet.

Intent intent = new Intent(Intents.ACTION_CUSTOMER_ADD_TIP);
intent.putExtra(Intents.EXTRA_AMOUNT, OrderAmount); 
intent.putExtra(Intents.EXTRA_ORDER_ID, OrderId);
startActivityForResult(intent, REQUEST_CODE_TIP);


@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    Log.d("TIP", "on result");

	if (requestCode == REQUEST_CODE_TIP) {
	    if (resultCode == Activity.RESULT_OK) {
        	Log.d("TIP", ""+data.getLongExtra(Intents.EXTRA_TIP_AMOUNT,0l));
	    } else if (resultCode == Activity.RESULT_CANCELED) {
        	Log.d("on result TIP", "cancelled");
    	    }
	}
}
