Subject Re: Unzip ANE for Flex\AIR Desktop App
Date Sun, 23 Oct 2016 13:28:53 GMT
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()*10000));

targetDir.createDirectory();

tempDirectoryForZip = targetDir;

var npInfo:NativeProcessStartupInfo = new NativeProcessStartupInfo;

npInfo.executable = NativeProgramsSettings.UNZIP;

var args:Vector.<String> = new Vector.<String>;

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
