emulator with SDK?
I assume the Android SDK come with some kind of emulator app?
I've messed around with the Appcelerator Titanium IDE, writing iOS apps in javascript. And from what i could gather, that would convert or wrap your code and then hand it off to either the iOS or Android SDK to compile and deploy into a emulator app running on your pc that'd show you how the app would run on a mobile. At least, that's how the iOS side worked, I assume it's the same process with the Android SDK.
