achartengine demo , no trace of R file

Question

I am trying to run achartengine demo source on my computer. I correctly import the zipfile(achartengine-1.0.0-demo-source.zip) into my workspace as a project. there is no gen folder at all.

and I checked; there are no "import Android.R" lines.

Then nearly every import line or method gets the "cannot be resolved" error. There is a line in the project explorer menu saying "unable to get system library for the project" I dunno what to do with that either.

So Eclipse suggests that I import Android.jar to my project and I do that. everything seems to be ok but there remains one problem.

There is still error in lines like this

import "org.achartengine.chartdemo.demo.R;"

Yes! Still, There exists no gen folder, thus no R file.

I know a R file has been imported within the android package but I cannot delete it. Also I checked and all my resources and xml names are lowercase.

Can anybody help me please? :)

Try to clean your project. Project > clean .This may help you. — Akshay, Aug 04 '12 at 12:04
organize imports in your activity then clean your project and then restart eclipse — Deepak Swami, Aug 04 '12 at 12:10

had the same problem. Solved. Do not import zip file. Extract zip file and import as existing project.

Plus you may run into error with @override statements: can be solved by setting compatibility to 1.6 level Java 7 language features with Android

Plus you may run into error during demo runtime - the solution here (see post by Shine) achartengine demo compiling, but runtime error

The R class and the gen directory are generated automatically by Eclipse, if you have the ADT plugin installed. Please see this as it may help you setup the project correctly.
