Project Components src – your source code gen – auto-generated code (usually just R.java) Included libraries Resources
Drawables (like .png images) Layouts Values (like strings)

Manifest file

XML
Used to define some of the resources

Manifest file Shouldn’t usually have to edit it directly, Eclipse can do that for you Preferred way of creating UIs
Separates the description of the layout from any actual code that controls it Can easily take a UI from one platform to another
