Getting errors when importing project to my android project

Getting errors when importing project to my android project

I want to use google maps clustering in my project. I am using this one:
https://github.com/twotoasters/clusterkraf
However I am getting issues when running my project. I was able to import
it fine. But when I run the app, I see on the console:
[2013-08-24 18:44:42 - library] Could not find library.apk!
I think its not importing the clusterkraf project (which is called
library) into my phone...
And when I try to run the code from this library in the phone, it throws
an exception and crashes. Here is the log:

I kept in my project properties Order and Export:

I don't know how to properly include it in the app when exporting. Does
anyone know how I can fix this?
Thanks.
