How do I link android library (as Angle) to my Eclipse project?

Question

Nooby question, I guess, but. I downloaded free android engine called Angle from here . There is a source and an example. I imported this project to Eclipse and now getting errors:

Project 'ANGLE' is missing required source folder: 'gen'    

and there was no such directory in package, so, I guess, I need to create it? In my helloWorld created without any libraries I have R.java in this folder (gen/com/companyName/appName/R.java).

Also, there was another error - project was for "android-3", and I have sdk beginning with 2.2 (android-8). So I changed target to android 2.2 and got an error

Android requires compiler compliance level 5.0 or 6.0.
Found '1.7' instead. Please use Android Tools > Fix Project Properties.

So, what are "android tools"? Never seen this option.

Thanks for any help. New to Eclipse, new to Android, so need some advices.
