You might not be familiar with GWT and PhoneGap. That’s okay. I’ll explain it all as we go forward. The important thing is that we are here to create great mobile apps.
The actual technology used to build software doesn’t really matter to the end user. People just want quality apps that look great and perform well. Unfortunately, the technology does matter when it comes down to actually building apps. Different platforms have their own toolchains and preferred languages. iPhone and iPad apps are largely written in Objective-C. Android apps are written in Google’s variant of Java. Windows Metro style apps use C#, C++, or Visual Basic. Add in webOS, BlackBerry (both old and new OSes), the Nook (older Android), and Kindle Fire (forked Android), and now we’ve got a problem.
To support all users we have to write our app at least three times, possibly many more if you count emerging TV platforms. And that’s the good news. The bad news is that it will only get worse. Mobile platforms are dividing not converging. Even among the Android family there are several major versions in widespread use, and the upgrade rate is sadly low.
