https://stackoverflow.com/a/4953458/1074880 I followed these instruction but didn't know what file to select after checking in my project properties.
Properties > Libraries (Unable to get system library for the project, Access rules: No rules defined, Native library location: (None)) > Add External JARs > program file > java > jre6 is it lib or bin then what do I select after that?

One solution is simply to import project. Then clean, if it doesn't work, delete project, then import again. I assume you click copy content to local when you import.
Another solution is to make a new android project and select create project from existing source.
Whatever solution is used you still sometimes have to do it multiple times for it to work...
