Pat Teglia (aka CrashTest_) of Palantir.net talks about the process of using Appcelerator’s Titanium framework to write JavaScript that is then compiled into native iPhone and Android applications. He collaborated with Larry Garfield and Jen Simmons to create the DrupalCon Chicago iPhone app and Android app. Teglia talks about the benefits of using the Titanium API over other mobile platform solutions like PhoneGap. He also explains how they used Views Datasource to get JSON-formatted data from the DrupalCon Chicago website that was then fed into the application (here’s an example of the presenter data and the session data.). Finally, talks a bit about the differences between what’s available to iPhone and Android apps and how you’re able to geo-location, accelerometer and the permissions-based features of the base mobile operating systems.
