I replace:
var zipFile = new air.ZipFile(datastream);
===================
For this:
var zipFile = new window.runtime.nochump.util.zip.ZipFile(datastream);

TypeError: Value undefined is not a constructor. Cannot be used with new.

My code is:

var urlStream = new air.URLStream();
urlStream.addEventListener(air.Event.COMPLETE, _completeHandler);

urlStream.load( new air.URLRequest( url ) );

function _completeHandler(event){
air.Introspector.Console.log(event);
var datastream = air.URLStream(event.target);
var zipFile = new air.ZipFile(datastream);
for(var i = 0; i <= zipFile.entries.length; i++) {
var entry = zipFile.entries[i];
air.Introspector.Console.log(entry.name);
}
}
