Error 1120: Access of undefined property air

I'm new with Air and I've found following code on the net:

code:

---

var file = air.File.applicationStorageDirectory.resolvePath("  test.txt");

var str = "Hello.";

file.addEventListener(air.Event.COMPLETE, fileSaved);

file.save(str);

function fileSaved(event)

{

air.trace("Done.");

}

---

But I get following errors:

Code:

---

1120: Access of undefined property air.    air.trace("Done.");

1120: Access of undefined property air.    var file = air.File.applicationStorageDirectory.resolvePath("test.txt");

1120: Access of undefined property air.    file.addEventListener(air.Event.COMPLETE, fileSaved);

I'm using Flash CS4. I also tried publishing but it didn't work. Can anyone help me?

remove .air from each of those lines.

It's not needed as you are programming in flash and not using the Air sdk

dudeqwerty, thanks for help. But this time it gave different error:

Code:

---

ReferenceError: Error #1069: Property save not found on flash.filesystem.File and there is no default value.
    at deleteme_fla::MainTimeline/frame1()[deleteme_fla.MainTimeline::frame1:7]

I made some corrections (var file:File / var str:String). But it gave different error: 1061: Call to a possibly undefined method save through a reference with static type flash.filesystem:File.

Ok, the problem here is that you are trying to use Air features, such as the file class, in Flash.

In order to use those features you will have to use the Air SDK: http://www.adobe.com/products/air/tools/sdk/

Code:

---

var data = "sdfs";
var target=File.documentsDirectory.resolvePath("airitems.txt");
if (target.exists) {
        return;
}
var fileStream = new FileStream();
fileStream.open(target, FileMode.WRITE);
fileStream.writeMultiByte(data, File.systemCharset);
fileStream.close();
