I mean if it’s posible having “x” application ver 1.0 installed, update this application from command line similar to the “airappinstaller.exe -silent airAppVer2.0.air” i recive “failed due to bad configuration error”.

thanks…

Thanks! I updated the post.

Please add some instructions about this to your document, I hope that nobody else has to struggle with this like I did.

great example which i have working on its own, but when i built into my app it doesn’t call onUpdate() after it has been initialize(d). Any thoughts on why this might happen?

Thanks Sander. This worked!

thanks, your kind words made my Samaritan personality happy

so in case anybody else feels like they in the dark, your compiled application that you wish to distribute must have it’s ..-app.xml version number the same as the version number within ‘update.xml’.

once you upload both your compiled *.air file and your ‘upadte.xml’ file to the server you are able to run a smooth update that gets rid of error:

#16824 Invalid update descriptor. subErrorID may provide more information.

to test this simply upload your files, and from within flash/flex drop your version number within …-app.xml and give it a test, you should now see error:

#16828 Cannot update application, usually because the application is running in the AIR Debug Launcher (ADL).

which means that the update process is actually working…

They have to be the same. You as a developer create a new version: 2.99. This is what you set in the AIR application, in the application descriptor file. Then you upload this to your server. Next you want any application already installed when is started to find this new version. To achieve this, you have to write the same 2.99 in the updater file.

Is it clear now?

@Rodrigo

Indeed, the whole point is to be able to push updates to clients. But this is how it is working:
- you install application with let say the version 1.0 on your machine;
- then you change in update.xml and …-app.xml the version to 1.1
- then you export the application and place it under your web server where update.xml is;
- then you open your installed application that will check for a new version and will do the update;

That still makes no sense to me? Why do the version numbers within app-xml.xml and update.xml have to be the same? Am I missing a point?

It shouuldn’t!

Here is the description for this error code:

16820 Invalid HTTP status code. subErrorID may contain the invalid status code.

Did you look at the comments, and still is not working?

and copied the applicationupdater_ui.swc from the frameworks/libs/air folder and the styles are now showing as they should!!

Thanks for the tutorial.

public function startApp():void {
checkUpdate();
}
private function checkUpdate():void {
appUpdater.updateURL = “127.0.0.1/update.xml”;
appUpdater.addEventListener(UpdateEvent.INITIALIZED, onUpdate);
appUpdater.addEventListener(ErrorEvent.ERROR, onError);
appUpdater.isCheckForUpdateVisible = false;
appUpdater.initialize();.// if i comment out this line then it doesn’t happen
}
private function onUpdate(event:UpdateEvent):void {
appUpdater.checkNow();
}
private function onError(event:ErrorEvent):void {
Alert.show(event.toString());
}

Thank you a lot for this post

I hope I managed to explain better this time.

Indeed, Sander has been right. Probably you have different versions inside of the two files: -app.xml and update.xml.

You can also check the subErrorId (or whatever) if you create an error handler for the DownloadError and use ApplicationUpdater instead of ApplicationUpdaterUI.

Any other suggestions would be really appreciated.

Cheers.

Regards.

Code is OK.
