I've got direct experience with this. I've built the same app on Android, iPHone & Blackberry and will soon be adding the WP7 app to the lineup. I was one of the Panelists at the iPhone vs Android talk a few months ago and I also presented on Android development at the SoCal Code Camp. I'd love to participate if you're interested.

Great, did you share the code in any way or was it a re-write for each one? What I was thinking of was around:

(1) HTML5 for mobile. Not too much web discussion though.
(2) Psuedo native apps, like with Titanium, Rhodes, or even PhoneGap where we pretend what comes out is native.
(3) Possibly Adobe AIR that seems have got new life for Android/BB (and iPhone if you count the packager for iPhone thing).
(4) Most importantly: sharing native C/C++/Java code with NDK etc. or stuff like MoSync.

I've been doing this cross platform approach for over 10 years and would love to see what the thinking is these days.

No, I built each one seperate. its really not as hard as you might think actually. Once you write the code for the first app, you work through all the intricacies of the business logic etc. Then when it comes time to build it on the next platform, you basically just translate from one to the other. I'm not a fan of these cross platform tools and I'd love to be a panelist to discuss why that is... :)

I just developed a social network app, in iPhone, Android and BB, will be glad to participate or hear other people expeinces

Would love to compare notes. Can we try for mid-Dec, like Wed. 15th? Any ideas for a venue, cheap or free?

Excellent idea. I'm new here. How can I help make this happen?

Our next talk is scheduled for Dec. 14th and will be discussing Android development. However, Cross-platform development is near and dear to me. I agree, let's put a panel together, but can we wait until mid-Jan?

Mid January sounds good to me, thanks Alex!

Hi Alex, Can I join the Android dev panel? I was on the Android vs. iPhone panel a few months back...

Hi Alex, What will be the time and place for the Dec 14th talk?

I changed the date and time to Friday, July 29, 2011 at 7:00 PM

Friday nights are generally not a good time for a meetup for many people.

Where is this meeting going to take place?

Anyone considering Appcelerator's "Titanium" product for this? (Not good for BB -- but looks promising for Android & iOS.

I changed the location to Qualcomm Building S

I removed the location. It was Qualcomm Building S

Hey guys, Any update where this will take place?

@Paul, I've tried Corona, Titanium and Phonegap. Phonegap is the best so far when attempting to integrate third-party jars. Corona and Titanium are very premature platforms, I would not recommend them.

OK, guys I am lost. I'd sent a message to Alex last Fri asking about what's going on, but never heard back - I guess he's busy. But Somya, I see you set the date for tomorrow...did you line up the speakers? Who's organizing this thing? Is Alex still the organizer for this group?
