    If you’ve recently updated to ADT 17 and above, they’ve changed the lib library handling.

    so you need to rename your lib dir to libs,
    then right click your project > properties > Java build path > Libraries > select all the jars with error markings on them and click remove > click add JARs > select all jars from your new libs dir.

    Hope this helps.
