Re: Unzip ANE for Flex\AIR Desktop App

[Fréderic Cox]

You can use File.applicationDirectory and put the 7za.exe in your project
folder. I placed it in /native_bin/win/7za.exe. Make sure the file has
"execute" permissions (right-click for properties of the file in Flash
Builder).

I have defined it as NativeProgramsSettings.UNZIP =
File.applicationDirectory.resolvePath("native_bin/win/7za.exe"); for
Windows and NativeProgramsSettings.UNZIP =
File.applicationDirectory.resolvePath("native_bin/mac/7za"); for Mac
(depending on Capabilities.OS)

Then for unzipping (I don't use zip functionality in my app) it is as
follows:

private function unzipNative(zipFile:File):void{

this.dispatchEvent(new Event("indicatorShowRequest"));

var targetDir:File = File.applicationStorageDirectory.resolvePath("unzipped"
);

targetDir.createDirectory();

targetDir = targetDir.resolvePath("unzip_" + new Date().time + "_" +
Math.round(Math.random()*1));

targetDir.createDirectory();

tempDirectoryForZip = targetDir;

var npInfo:NativeProcessStartupInfo = new NativeProcessStartupInfo;

npInfo.executable = NativeProgramsSettings.UNZIP;

var args:Vector. = new Vector.;

args.push("x");

args.push(zipFile.nativePath);

args.push("-r");

args.push("-o" + targetDir.nativePath);

npInfo.arguments = args;

var np:NativeProcess = new NativeProcess;

np.addEventListener(NativeProcessExitEvent.EXIT, npUnzipExitHandler);

np.start(npInfo);

}


For zip you need to have different arguments of course. You can check by
googling "7za command line".


Hope it works for you

Re: Unzip ANE for Flex\AIR Desktop App

[Deepak MS]

Interesting. I never knew about that. Doesn't that mean user needs to have
7za installed on their systems? If so, what if users don't have it
installed. Can we package the 7za.exe within our AIR app and use it?

I looked into some of the examples. But not quite getting it to work:

Same code with pretty print : https://codepaste.net/82gk2q


if(NativeProcess.isSupported)
{
var nativeProcessStartupInfo:NativeProcessStartupInfo = new
NativeProcessStartupInfo();
var file:File = new File('c://zip//7za.exe'); //instead of using it from
local file system, i want to place exe file withing source and use it here
nativeProcessStartupInfo.executable = file;
var processArgs:Vector. = new Vector.();
processArgs.push("7z e file.zip");//+localZipFile.nativePath); //"file.zip"
resides inside "c://zip//", tried "7za e file.zip", tried "7za.exe
file.zip", none of those work
nativeProcessStartupInfo.arguments = processArgs;
process = new NativeProcess();
process.start(nativeProcessStartupInfo);
process.addEventListener(ProgressEvent.STANDARD_OUTPUT_DATA, onOutputData);
process.addEventListener(ProgressEvent.STANDARD_ERROR_DATA, onErrorData);
process.addEventListener(NativeProcessExitEvent.EXIT, onExit);
process.addEventListener(IOErrorEvent.STANDARD_OUTPUT_IO_ERROR, onIOError);
process.addEventListener(IOErrorEvent.STANDARD_ERROR_IO_ERROR, onIOError);
}

For all the options that i tried above, I get following trace:

(onOutputData)
Got:
7-Zip (A) 9.20  Copyright (c) 1999-2010 Igor Pavlov  2010-11-18

(onErrorData)
Error:
Incorrect command line

(onExit)
Process exited with  7


Kindly let me know if I am missing something there.

Re: Unzip ANE for Flex\AIR Desktop App

[Fréderic Cox]

I successfully used 7za for both Mac and Windows. You don't need a native
extension for desktop but you can just use the NativeProcess API with the
extendedDesktop profile.

Re: Unzip ANE for Flex\AIR Desktop App

[Deepak MS]

Hi Hans,
Yes, I did try that. It works fine for smaller files. But unfortunately,
unzipping process crashes if we use it for bigger files. My zip file size
is around 500MB.  It fails at ByteArray.uncompress() as it tries to
uncompress entire file at a time. That is the reason I was looking out for
native way of unzipping the file.

For iOS, I have used ANEZipFile library :
https://github.com/xperiments/ANEZipFile

It works flawlessly and takes just 5 - 6 seconds to unzip a 500MB zip file.
That is just for iOS though.

There is another library:
http://airnativeextensions.com/extension/com.distriqt.ZipUtils which works
on both iOS and Android, but it's not free.

-Deepak

Re: Unzip ANE for Flex\AIR Desktop App

[Hans Nuecke]

Hi,

I use an openSource Library for that: 
http://flex.coltware.com/2010/05/01/as3-zip-unzip-lib-airxzip/


Search for keywords "coltware airxzip" and you'll find some nice posts 
at stackoverflow with links to the sources or a swc file. And also hints 
how to use it.


BTW: What unzipt ANE are you using? I'm considering going the other way: 
convert my desktop APP (or better: parts of it) to an iOS/Android app

Hans
