I had to abandon the Library Project approach in the end because I was running into so many eclipse errors it was really slowing me down. This is particularly true when refactoring - which, I suppose, is the first thing people do when changing their code to use libraries.
For example, if your Library project depends on a Java project and you do things like rename packages in that Java project, then eclipse would throw up an error (unfortunately can't remember which one). Restarting eclipse didn't seem to make a difference. Workaround was to create a new package and move classes into that. Didn't isolate the problem so there might be other factors involved here - like another Android project also depending on that Java project.
