I downloaded and test HTC opensense SDK . But I can’t test any sample application . The main.xml file in the layout show like this

The following classes could not be found:

  • com.htc.painting.engine.HTCPaintingView (Fix Build Path, Edit XML,
    Create Class)
  • com.htc.painting.penmenu.PenMenu (Fix Build Path, Edit XML, Create
    Class)

How can I solve this problem ?

I see log cat error like this
