Every time the Android project is built, it's dexed and put into a debug-signed apk that is sent to your phone/emulator. Hence, hotswapping isn't exactly easy to do. Hotswap is a product of a well-designed JVM, and it makes it possible to exchange classes. On Android, you have Dalvik VM, which does not currently support hot swapping. I'm guessing the ADT team has this high-ish on their list, though. EDIT: Even though it has been 2,5 years since this answer, not much has changed. ZeroTurnaround, however, have stuff up their sleeves, and JRebel for Android should give us a much needed method for hot swapping.

By design the new Android Emulator is actually faster in most cases than a physical Android device. See my talk on this from the Android Developer Summit, where we launched the new Android Emulator. [this video] OpenGL ES graphics is specifically faster than most Android physical devices because if you used the default configuration when you setup your AVD, we directly utilize the host GPU on your laptop to render OpenGL ES instructions from your Android app. Even GPU card on a mid-tier laptop is somewhat slower than an Android phone GPU.
