I downloaded the [Robotium](http://code.google.com/p/robotium/) jar as well as javadoc jar file. I then created a folder called libs and pasted the two jars into it. I went to properties,libraries tab and add jar and selected the main jar in my libs directory. I then tried to add the javadoc.jar to the javadoc location. It still does not show me any documentation. Does anyone know why?
