When using setOnGroupClickListener method report an error “cannot find symbol”

When using setOnGroupClickListener method report an error “cannot find symbol”，
I try to use setOnGroupClickListener to register sublist click event listener to list control，But an error is reported during compilation

Remove Unknown tags (C3, BF40, C2) from TLV using TLVUtility on terminalSdk-2.0.3.jar

I am trying to remove some Unknown tags (C3, BF40, C2,.. etc) from ByteArray using TLVUtility (mastercard class from terminalSdk-2.0.3.jar), Tags was not removing from the ByteArray. I am trying like this,
Here is my TLV Data I have,
ppseResponse = ByteUtility.hexStringToByteArray("6F54840E325041592E5359532E4444463031C30F4920414D2054484520424553542033BF4003C20101A52BBF0C28610C4F07A0000000041010870101610C4F07A0000000043060870103610A4F05B0123456788701099000")
I am trying this to remove the Unknown tags like,
"BEFORE << ${ByteUtility.byteArrayToHexString(ppseResponse)}".toLog(activity, TAG) //To print Log
val unknownTags = byteArrayOf((0x00C3).toByte(),(0xBF40).toByte(), (0x00C2).toByte())
var removed = TLVUtility.removeTag(ppseResponse, ContentType.TLV,unknownTags)
"AFTER << ${ByteUtility.byteArrayToHexString(removed)}".toLog(activity, TAG) //To print Log
Here is the function removeTag on terminalSdk-2.0.3.jar function look likes,

I fixed this issue by creating new custom function. Here is the function. Now on this function I am removing all the Unknown Tags and its Skipping all Known Tags and Third party data and Optional Tags Tags
First we need to define optional Tag,
private var optionalTags: ArrayList<ByteArray> = getOptionalTags()
Here is the function I am adding Optional Tags,
private fun getOptionalTags(): ArrayList<ByteArray> {
optionalTags = ArrayList()
optionalTags.add(ByteUtility.hexStringToByteArray("9F3E")) //Terminal Categories Supported List
optionalTags.add(ByteUtility.hexStringToByteArray("9F3F")) //Selection Data Object List
optionalTags.add(ByteUtility.hexStringToByteArray("9F2A")) //Kernel Identifier
optionalTags.add(ByteUtility.hexStringToByteArray("9F0A")) //Application Selection Registered Proprietary Data
return optionalTags
}
Here is the function to remove the Unknown tags,
private fun removeUnknownTags(ppseResponse: ByteArray): ByteArray {
var parentTags: MutableMap<ByteArray, Int> = LinkedHashMap()
var ppseResp = ppseResponse;
var i = 0
"PPSE (Length: ${ppseResp.size}) : HexString: ${ByteUtility.byteArrayToHexString(ppseResp)} \n ByteArray: ${ppseResp.toList()}".toLog()

for (tag in parentTags.entries.reversed()) {

Exchange rate currency format setting in Flutter

I have an exchange rate application in flutter, but I want to make the currency format the same as below, how can I do it?
My Code :
import 'package:flutter/services.dart';
import 'package:intl/intl.dart';
import '../Utils.dart';
class CurrencyInputFormatter extends TextInputFormatter {
TextEditingValue formatEditUpdate(
TextEditingValue oldValue, TextEditingValue newValue) {
if (newValue.selection.baseOffset == 0) {
print(true);
return newValue;
}
double value = double.parse(newValue.text);
final formatter = NumberFormat("#,##0", "tr-TR");
String newText = formatter.format(value);
print(newText);
return newValue.copyWith(
text: newText,
selection: new TextSelection.collapsed(offset: newText.length));
}
}
I want to do

Intl actually provides you a way to do so.
import 'package:intl/intl.dart';
final moneyText = 1000;
NumberFormat.simpleCurrency().format(moneyText);
If you are already using translation, you should have intl already.

You can achieve this with flutter_masked_text package it can do exactly the same.

I solved. works great.
library currency_text_input_formatter;
import 'dart:math';
import 'package:flutter/services.dart';
import 'package:intl/intl.dart';

/// Put '\$' for symbol

/// Defaults `decimalDigits` is 2.

#override

} else if (newValue.text == ".") {
return newValue.copyWith(

selection: TextSelection.collapsed(offset: 2),
);
} else {
NumberFormat f = NumberFormat("#,###,###.00", "en_US");
double newNumber = 0;
if ((!newValue.text.contains(".")) && oldValue.text.contains('.')) {
String tempString = newValue.text.replaceAll(f.symbols.GROUP_SEP, '');
tempString = tempString.substring(0, tempString.length - 2) +

newNumber = double.parse(tempString);
} else {

}
String newString = f.format(newNumber);
int cursorPosition = 0;

Haxe, OpenFL android debug giving error in for cpp

I'm developing an app in FlashDevelop, using Haxe and OpenFl
When I test my app in flash target, it works fine. But when I compile for android, it comes up with this error during the compilation:
./src/ReaderView2.cpp: In member function 'virtual Void ReaderView2_obj::setZoom()':
./src/ReaderView2.cpp:653: error: base operand of '->' has non-pointer type 'String'
Build halted with errors (haxelib.exe).
...Which is obviously something to do with cpp, which I'm not really an expert.
Does any body know what the error means?
Here's the setZooom function: (the whole file is quite large)
public function setZoom()
{
hideOptions();
while (numChildren > 0)
{
Main.remove(getChildAt(0));
}
if (image != null) if (image.parent != null) image.parent.removeChild(image);
images = new Array();
field = new TextField();
var fieldFont = Assets.getFont("fonts/Kreon-Regular.ttf");
var format:TextFormat = new TextFormat(fieldFont.fontName, currentZoom, 0x4F4F4F);
format.align = TextFormatAlign.LEFT;
field.defaultTextFormat = format;
field.embedFonts = true;
field.text = fullText;
field.selectable = false;
field.wordWrap = true;
field.border = false;
field.autoSize = TextFieldAutoSize.LEFT;
field.width = displayWidth;
//field.x = 0;
//split string into words
var allParas:Array<String> = fullText.split("\r\n");
var words:Array<String>;
var fields:Array<TextField> = new Array();
var tempField:TextField = null;
var contentHeight:Float = displayHeight;
var wordI:Int;
var paraI:Int = 0;
var tempArr2:Array<String>;
while (paraI < allParas.length)
{
if (false) //check img tag
{
}
else //if para is words
{
wordI = 0;
words = allParas[paraI].split(" ");
while (wordI < words.length)
{
if (tempField == null || tempField.textHeight > contentHeight)
{
if (tempField != null) {
wordI--;
tempArr2 = tempField.text.toString().split(" ");
for (i in 0... tempArr2.length)
{
tempArr2.remove("");
}
tempArr2.pop();
tempField.text = tempArr2.join(" ");
}
tempField = new TextField();
tempField.defaultTextFormat = field.getTextFormat();
tempField.embedFonts = true;
tempField.text = "";
tempField.border = false;
tempField.selectable = false;
tempField.wordWrap = true;
tempField.autoSize = TextFieldAutoSize.LEFT;
tempField.width = displayWidth-2;
tempField.x = 0;
fields.push(tempField);
}
else
{
tempField.appendText(words[wordI] + (wordI == words.length - 1? "\n": " "));
wordI++;
}
}
}
paraI++;
}
var bd:BitmapData;
for (i in 0... fields.length)
{
bd = new BitmapData(Std.int(fields[i].width), Std.int(fields[i].height));
bd.draw(fields[i]);
images.push(new Bitmap(bd, PixelSnapping.AUTO, true));
}
//addChild(fields[0]);
images[0].x = 10;
addChild(images[0]);
currentPageInstance = images[0];
currentPage = 0;
drawScrollBar();
if (optionsBtn!=null)addChild(optionsBtn);
}

So apparently using the toString() funcion gives problems for a cpp target.

Unable to receive values more than 255 on Android device from Arduino

I am developing an application to receive data on an Android device from an Arduino. It displays values only up to 255 when I convert it to integer, but I want those values which are sent by the Arduino board. I have tried converting them to strings but that didn't work either.

It looks like the problem is in the Arduino sketch. The msg array contains (unsigned) bytes which have a maximum value of 255.
The line:
msg[1] = value/10
implicitly truncates value/10 (which is an integer between 0 and 1023 - see http://arduino.cc/en/Reference/analogRead) to a maximum of 255.
To send value/10 you'll need to split it over 2 bytes. For example:
msg[1] = (uint8_t) (i & 0xFF);
msg[2] = (uint8_t) ((i >> 8) & 0xFF);
And msg will have to be one byte longer to accomodate.
On the Android (Java) side you'll need to do something like:
int value = (int) buffer[0];
// ...
int tds = buffer[1] + (buffer[2] << 8);
m.obj = new ValueMsg('f', value, ret, tds,
buffer[3], buffer[4], buffer[5], buffer[6]);
which will require a change to the definition of ValueMsg to accomodate.
Also, there may be a problem with the calls to SndData (assuming the library being used here is the USB_Host_Shield_2.0) as they always send 6 bytes even though in the first time through loop all 6 bytes of msg won't have been initialized.
