Compiling takes place on the development machine after we click on that button. We will see this work right after we set up our development environment in a minute.
Android is a complex system, but you do not need to understand it in depth, in fact, it is designed to hide the complexity, all operating systems are, and Android does this better than most.
The part of the Android system that executes (runs) our compiled DEX code is called the Dalvik Virtual ...
