I would like to develop a cross-platform application for mobile phones as I would like to just programe once and have the app for the differents platforms we have nowadays.
I took a look of the differents frameworks there are and I would like to skip all of the web bases frameworks, like phonegap, which uses html/javascript, as I feel the applications developed with those framework will not have a good performance. I prefer to develop native applications.
With that in mind, I found LiveCode or Xamarin which look interesting but since I don't have any experiencie with them, I'm not really sure of which one I should take. Apparently, for instance, Xamarin doesn't share all the code you develop...
I need some suggestions and advices with this as I will have to learn to use the framework from the beggining and I don't want to waste my time!
So, any experiencie using any of those frameworks? suggestions? advices?
