Hi folks! Today, while mounting some of my projects into AIR, I realized that it would be great if I could pusblish AIR badges over Facebook. You know what? That is possible! I have created a simple flex application + facebook application that, based on parameters, generates AIR badge for an app. Now its time to share the stuff with you, feel free to publish your AIR badges, and let me know how do you like it.
Here is a quick tip how to check the version of your installed AIR application from an application running in flash player. In order to make your AIR application (system) be able to respond to the requests for installed version correctly you need to define allowBrowserInvocation within your AIR descriptor file (app.xml). If you don’t do this, you won’t be able to query version information on your application:
<allowBrowserInvocation>true</allowBrowserInvocation>
Now your AIR application will respond correctly with its installed version. With this setting on, the installed AIR application can be launched via the browser invocation feature (by the user clicking a link in a page in a web browser). Be sure to consider security implications.
Now, to get version info from any application running in flash player (or AIR) you simply call getApplicationVersion() method on air.swf file located on adobe domain.
Even if it stands in documentstion (some crucial things mentioned in one line somewhere), it was really tricky thing to figure out how to make LocalConnection-s work between different application runtimes (flash player / air). It got even more tangled with empty flash player error saying “Error #2044: Unhandled StatusEvent:. level=error, code=”. Basically, there is a generic method/form, with underscore prefix for connection name, that you can successfully use in all cases, but if your application requires higher security you should define your connections more exactly.
Based on your applications origin (AIR / flash player) you may define a few types of communication nature:
