Three Platforms, One application: MobileTrader for iOS, Android, and PlayBook Source Code Available

My recent video, Flex on the iPad, has generated a lot of interest. The same application runs on iOS, Android, and the BlackBerry PlayBook. A number of you have asked me for the source code. Now that Flex 4.5 has been released, I’m able to share it: you can download the project file here.

NOTE: The shipping version of Flash Builder 4.5 provides full support for Flex projects on Android. Support for Flex projects on iOS and the PlayBook will be available in a June update. More information here.

Usual disclaimer about the source code: This is a sample application, I intentionally cut some corners, etc.

    I was under the impression that the Android apps were running as native apps but it seems that they still require the user to install the AIR runtime. Do you know if there are any plans to have stand-alone native apps like what is being done for iOS?

    I believe having to install AIR is a large barrier to entry for users.

    Thanks for sharing,

    Greats demo apps, by the way !!!

    I was wondering: Why did you not use chart components to draw charts ?
    I guess it’s for performance issue but i have read that we can still use it for mobile app development

    First of all, I am a big fan of Flex and Air, but I have to agree with Matt. Correctly if I am wrong, and I hope I am wrong, but background and startup apps are not possible due to Air restrictions. Is this correct? I need to have the capability of running background applications on these devices as well as having the applications launch in the background upon startup.

    Unfortunately, I am not a Java develper nor do I have a Jave background. Be nice if actionscript/flex/air had the wrappers for you.

    Thanks for the link.
