I want to start developing mobile applications but I'm a littlte confused about all the posible options. What lenguage or framework would you recommend me to learn? what should be my first steps?Obviously I would like to learn the technology with more future in the market. I already have knowledge of J2SE. Any additional recommendations are welcome
Well, we're a little bit biased here, but we like Java. At the moment, the 2 primary options in that area are Android and JME. Android is, of course, very hot these days, but JME has its uses, and if you want to target the still-popular Blackberry platform, it's J2ME-based.
Microsoft, of course. likes .Net (or at least did up until last week). Then there's Palm's WebOS. Nokian flooded the world with Symbian phones, which I think are C/C++. although now Nokia loves Microsoft. Then there's the one and only iPhone, which is programmed in Objective-C.
Although each platform has its own primary language, you can often find secondary languages being used as well. For example, Python on Android.
An IDE is no substitute for an Intelligent Developer.
