A few interesting pieces of data: 70% of the world’s population has a mobile phone over a million Android devices are activated weekly 1/2 of all local searches are done on a mobile device over 90% of mobile Internet access is social media related Clearly, if you aren’t building mobile apps today, you will be soon. And if you want to build Android apps as fast as people can consume them, then I recommend you check out Ruboto, a framework that leverages the power of JRuby to enable you to quickly build and deploy Android apps. As you’ll see, with the expressiveness of Ruby and the full stack nature of this Rails-like framework, you can go from idea to device in short-order. Follow along as some hipster (hint, he’s the coolest disco dancer you read about all the time or at least right this instant) demonstrates using the Ruboto framework to rapidly build and deploy Android applications. See how to create an emulator instance, create a Ruboto project using the command line, code your app, and use a location listener for obtaining GPS information. Java
