AutoUpdate of AIR application - actionscript

Question

I am learning Auto-update feature of AIR application. I created simple application which is not working. code is below:
AutoUpdate.mxml
<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"
creationComplete="checkForUpdate()" >
<fx:Script><![CDATA[
import air.update.ApplicationUpdaterUI;
import air.update.events.UpdateEvent;
private var appUpdater:ApplicationUpdaterUI=new ApplicationUpdaterUI();
private function checkForUpdate():void
{
setApplicationVersion();
appUpdater.delay = 1;
appUpdater.isDownloadProgressVisible = true;
appUpdater.isDownloadUpdateVisible = true
appUpdater.isInstallUpdateVisible = true;
appUpdater.isFileUpdateVisible = true;
appUpdater.updateURL = "http://localhost:8081/DynamicWeb/release/update.xml";
appUpdater.isCheckForUpdateVisible = false;
appUpdater.addEventListener(UpdateEvent.INITIALIZED, onUpdate);
appUpdater.addEventListener(ErrorEvent.ERROR, onError);
appUpdater.initialize();
}
}
// Find the current version for our Label below
private function setApplicationVersion():void
{
var appXML:XML = NativeApplication.nativeApplication.applicationDescriptor;
var ns:Namespace = appXML.namespace();
lbl.text = "Current version is " + appXML.ns::version;
//Common.helpDetails = appXML.ns::versionLabel;
}
private function onError(event:ErrorEvent):void
{
//Alert.show(event.toString());
}
private function onUpdate(event:UpdateEvent):void
{
appUpdater.checkNow(); // Go check for an update now }
}
]]></fx:Script>
<s:HGroup x="89" y="124" width="413" height="34">
<s:Label id="lbl" />
</s:HGroup>
</s:WindowedApplication>
*Initially in AutoUpdate-app.xml and update.xml file version tag is set to 1.0.0
* server side update.xml file is :
<?xml version="1.0" encoding="UTF-8"?>
<update xmlns="http://ns.adobe.com/air/framework/update/description/1.0">
<version>1.0.0</version>
<url>http://localhost:8081/DynamicWeb/release/Update_air.air</url>
<description><![CDATA[
Typically, this is used to summarize what's new in the release
]]></description>
</update>
Now I have exported application and installed it. After that i changed version on both file AutoUpdate-app.mxml and update.xml(server side) to 2.0.0 . Now i exported the application and dumped it to server (in 'release' folder where update.xml is there.).
Now when i launch the application , Update feature is not working. Its nothing happening.
CheckNow() method is called but doing nothing. Please help me.
I am working on AIR 3.1
Its not giving any kind of error. Only Updation Window is not working.
Please tell me what i m doing wrong. Thanks.

Answer 1

1) trace real version and from update.xml and be sure you did it correct. You must be sure you run old app with 1.0.0 version. BTW, you can use property ApplicationUpdaterUI.currentVersion instead of NativeApplication.nativeApplication.applicationDescriptor
2) You do not listen events after checkNow() calling. Listen all events, like in this article. In
http://thanksmister.com/2009/09/13/custom-air-updater-interface-using-applicationupdater/ (see UpdateManager.as#initialize()):
appUpdater.addEventListener(UpdateEvent.INITIALIZED, updaterEvent);
appUpdater.addEventListener(StatusUpdateEvent.UPDATE_STATUS, updaterEvent);
appUpdater.addEventListener(UpdateEvent.BEFORE_INSTALL, updaterEvent);
appUpdater.addEventListener(StatusUpdateErrorEvent.UPDATE_ERROR, updaterEvent);
appUpdater.addEventListener(UpdateEvent.DOWNLOAD_START, updaterEvent);
appUpdater.addEventListener(ProgressEvent.PROGRESS, updaterEvent);
appUpdater.addEventListener(UpdateEvent.DOWNLOAD_COMPLETE, updaterEvent);
appUpdater.addEventListener(DownloadErrorEvent.DOWNLOAD_ERROR, updaterEvent);
appUpdater.addEventListener(ErrorEvent.ERROR, updaterEvent);
private function updaterEvent(event : Event) : void {
trace(event.type);
}
possible, you missed some thing...

Answer 2

in your server side update.xml you should replace the tag version with versionNumber.
This changed since AIR 2.5.
