Show progress bar and percents when packaging a native installer with adt packager

Hello,

Below is a simple example using the AIR's NativeProcess for compiling an air application into a native installer... Everything works fine, so at the end of the NativeProcess, the native installer (*.exe) is created... In this case, the application which I'm trying to compile is small (approx. 600KB)... However, if I have to package into native installer a bigger file (several MBs), I would like also to monitor the progress by using a progress bar and percents... How?

private var file:Fileprivate var nativeProcessStartupInfo:NativeProcessStartupInfo;private var nativeProcess:NativeProcess; private function compile():void{  file = new File("C:\\Program Files\\Java\\jre7\\bin\\java.exe");  nativeProcessStartupInfo = new NativeProcessStartupInfo();  var args:Vector.<String> = new Vector.<String>();  args.push("-jar");  args.push(adtPath);  args.push("-package");  args.push("-storetype");  args.push("pkcs12");  args.push("-keystore");  args.push(certPath);  args.push("-storepass");  args.push("mypass");  args.push("-target");  args.push("native");  args.push(exePath);  args.push(xmlPath);  args.push("-C");  args.push(swfPath);  args.push("testApp.swf");  args.push("icons");  nativeProcessStartupInfo.arguments = args;  nativeProcessStartupInfo.executable = file;  nativeProcess = new NativeProcess();  nativeProcess.addEventListener(ProgressEvent.STANDARD_OUTPUT_DATA, onOutputData);  nativeProcess.addEventListener(ProgressEvent.STANDARD_ERROR_DATA, onErrorData);  nativeProcess.start(nativeProcessStartupInfo);}private function onOutputData(event:ProgressEvent):void{   var op:String =  nativeProcess.standardOutput.readUTFBytes(nativeProcess.standardOutput.bytesAvailable);   trace("output = " + op);}private function onErrorData(event:ProgressEvent):void{   var er:String = nativeProcess.standardError.readUTFBytes(nativeProcess.standardError.bytesAvailable);   trace("error = " + er);}

Thanks in advance,

Nikola
