Hi, I just want to throw in that I have been doing a bunch of apps with Flex mobile and am constantly amazed at how good it performs across devices. I am talking about data intensive visualizations with a lot of number crunching, charts and animations.
Of course, as with Objective-C or Java, you need to be very careful about orchestrating your code so that it does not choke the system. And I have been testing the apps on my Galaxy Tab and iPad, and all real issues I have been facing is related to dpi mismatches and such. So, when folks are saying that Flex does not perform well on mobile, can you please post some examples, etc so we can try to figure out what the real problems? As opposed to sweeping statements like Flex mobile sucks, etc. Thanks, Om On Thu, Jun 27, 2013 at 2:23 PM, Alain Ekambi <jazzmatad...@gmail.com>wrote: > @Alex > > I can share my experience concerning 1) > > Most of our customers dont want to migrate their app to JS. > What they want is an easy way to integrate exiting JS libraries into their > Flex app. > For example hoe to integrate the JS Google Maps API with their existing > Flex apps or How can I integrate my nice Flex DateGrid into this Ext JS > application ? > > I said it once.
