Integration with Android studio breaks R file navigation

[georgepapas]

When introducing robospock into the my test project, android studio is no longer able to navigate to the actual R file value definitions, as defined in xml, or the layout definitions. i.e. If I have the following project structure

- app
- unit-test (robospock)

then when I'm in say an activity and ctrl-click from an R reference to get to the actual definition, android studio takes me to the r.class file instead of the actual definition. I can only think that somehow, adding the main apps java source sets as source sets in the the 'unit-test' project confuse studio in some way.

Any suggestions as to how to resolve this? I've experimented with adding just the main apps classpath and output dir as a classpath dependency of the test-app and although the tests run, we loose the nicety of source file -> test file navigation via the ide. Any suggestions would be appreciated...
