It is widely believed that Android app development has to be done in Java -- but this is not true. Aside from using JNI, there are some interesting, but not very well documented, helpers that allow writing apps without having to touch Java.
This session will explain how to write Android apps in different programming languages -- such as C, C++ and Objective-C -- any touches on why you may want to do such a thing even though Java on Android is good.
Developers who want to develop Android apps in languages other than Java - whether this is for porting (porting an Objective-C application from that other mobile OS may be easier than you think...), using a pre-existing library that doesn't have reasonable Java bindings, or simply because of personal preference.
This will help people understand how (and that) they can develop Android applications without having to use Java - this will help porting applications from other operating systems as well as bringing in developers who are interested in mobile devices, but don't like Java.
