Hello,
I am Actionscript 3.0 programmer working in Flash, Flex/Flash Builder and Adobe Air. Please have a look at my feedback for further reference, https://www.freelancer.com/u/programmerAS3.html . I have just finished doing AS3+Flash Builder 4.6+mobile project and the feedback should be there by this week.
Regarding the project, is this earlier done in Flash Builder 4.5 or 4.6/4.7? Is their any framework implemented inside the code ? So you wanted to load the web version on the app but play the local files inside the app with that loaded version. Sounds bit tricky, but possible too. There should be specific web version for this app. Normally after loading the web on AS3, it is out of control to bind/detect the web controls. So having a specific web version that could be tweak according to the needs of the app should help here.
I should be online almost most time of the day, so communication should not be that problem. I am at GMT +5:45. Let me know, if you would like to know more on anything.
Regards
