Session Presented at 1st IndicThreads.com Conference On Mobile Application Development held on 19-20 November 2010 in Pune, India

Speaker: Rohit Nayak

Abstract:

Mobile development is still in a nascent stage. New platforms keep emerging and old ones regularly undergo major changes. To confuse matters further there are several cross-platform tools each claiming to use a single codebase to target multiple phones. What is a developer to do?

In this talk we will look at some of the key cross-platform mobile platforms out there including Appcelarator Titanium, PhoneGap and MoSync. We will start out by reviewing the different mobile platforms and development environments before reviewing the landscape of cross-platform tools. We will discuss the different design approaches used by these platforms to support their target smart-phones. Quick demos using a few of these platforms will be shown so that the audience will get a flavor of the low level coding details as well as supporting tools like IDEs and simulators provided. Java and QT are traditional cross-platform environments which have a place in mobile development as well. We will take a quick look at support available for these on mobile platforms. Finally we compare the different approaches in terms of functional limitations, programming complexity, deployment and lock-in.

Takeaways from the session
Review of the mobile single platform and cross platform landscape
Should I look at cross-platform development or not?
Which cross-platform tools make sense for me?
What kind of developers do I need for cross-platform development?
