Hi, I just downloaded and installed the ArcGIS API SDK today and I am working through the hello world app. However, I am getting a bunch of errors because none of the android classes like Activity, String, Object are loading. It seems to be something with the build path and when I open up the project properties>Java Build Path, Order and Export tab I have an item that says "Unable to get system library for the project". I think this is my problem but I don't know how to fix it. If any can offer help on the situation it would be very appreciated. Thanks!
