Building Adobe AIR Applications

BUILDING ADOBE AIR APPLICATIONS
Updating AIR applications
3 Create a text file named updateConfig.xml and add the following to it:
http://example.com/updates/update.xml
1
Edit the URL element of the updateConfig.xml file to match the eventual location of the update descriptor file on
your web server (see the next procedure).
The delay is the number of days the application waits between checks for updates.
4 Add the updateConfig.xml file to the project directory of your AIR application.
5 Have the updater object reference the updateConfig.xml file, and call the object’s initialize() method.
In ActionScript, use the following code:
appUpdater.configurationFile = new File("app:/updateConfig.xml");
appUpdater.initialize();
In JavaScript, use the following code:
appUpdater.configurationFile = new air.File("app:/updateConfig.xml");
appUpdater.initialize();
6 Create a second version of the AIR application that has a different version than the first application. (The version
is specified in the application descriptor file, in the version element.)
Next, add the update version of the AIR application to your web server:
1 Place the update version of the AIR file on your web server.
2 Create a text file named updateDescriptor.2.5.xml, and add the following contents to it:
1.1
http://example.com/updates/sample_1.1.air
This is the latest version of the Sample application.
Edit the versionNumber, URL, and description of the updateDescriptor.xml file to match your update AIR file.
This update descriptor format is used by applications using the update framework included with the AIR 2.5 SDK
(and later).
3 Create a text file named updateDescriptor.1.0.xml, and add the following contents to it:
1.1
http://example.com/updates/sample_1.1.air
This is the latest version of the Sample application.
Edit the version, URL, and description of the updateDescriptor.xml file to match your update AIR file. This
update descriptor format is used by applications using the update framework included with the AIR 2 SDK (and
earlier).
Note: Creating this second update descriptor file is only necessary when you are supporting updates to applications
created prior to AIR 2.5.
