if it is not, why should you go native with c/c++ based ndk programming? it is surely related to the programming language.
javascript 's speed acceleration is also related to the language and its optimization, which is almost always c/c++. i have never experienced the fast feeling of java technology both in desktop or server side. i never experienced fast feeling in android, eclipse, java ee, j2me. am i fooled? eclipse is famous for it's slow and memory consuming, though it is the greatest ide i ever used. javascript based ide, like local compiled c9.io is very fast and responsive, thought it is not that mature. why ? ? ? and if android ui design can be written directly in html + css, it has all the flexibility css and html have now. If you know the web technologies, you should know what i mean. it is meaningless to discuss about the languages' performance, but the trend is that javascript will play a more important role in server side programming, hardware based programming and browser side programming. 2014-05-12 1:03 GMT+08:00 Colin M <[email protected]>: > I'll ignore the unqualified claim that the slowness of Android is due to > Java. > > It sounds like your complaint is that you can't develop native apps in > your preferred language and that you're using an outdated claim about Java > to support your desire to change the current language of choice for Android > development. > > The XML based components can all be done via code.
