Also, is there a fully-qualified import statement already in the source 
file, for a Layer class or interface? If not, what is the package of the 
class that needs Layer? These are ways of identifying what Layer is 
required, that and looking at the source to see what kinds of methods 
are invoked on Layer objects, and matching that with APIs you discover 
by Googling.

It's not a safe attitude to "get past" errors, not with imports nor 
anything else. And even if you've got a number of libraries that supply 
class X, and you can successfully compile with several, only one may be 
correct at runtime. Don't rely on your IDE to make the right suggestion, 
it can only know the possibilities: you yourself must know what you need.
