  • So what’s my goal today? Here’s what I want you to walk away with. After this session I’d like you to walk away with…CHECK TO SEE IF ANYONE HAS jQuery Mobile experience or Rails experience
  • I hate powerpoint so I’m going to try to get through these slides as quickly as possible and dive into code.
  • The choice is getting harder with each passing day. Depends on the type of application, development skills and target audience:First person shooter… native. A lead entry system…. HTML5If you have a lot of hard-core Java guy… go native Android. More web developers… go HTML5If you are like Instagram and only targeting iPhones… go native iOS. If you want your app to run “everywhere”… go HTML5.You see more and more companies like salesforce.com, Facebook and LinkedIn going hybrid. Don’t want to support multiple builds for different platforms.
  • This slide should be called, “What is PhoneGap so AWESOME!”Think of it as a native wrapper around web apps that provides access to native functionality
  • So now that we know a little more about mobile app dev, let’s build something.LinkedInHackday finalist
