[android-developers] Re: AndroidTestCase fails with dependency on third project

I'm a bit confused here. You say that the tests run successfully in
the emulator, correct? Is this under Eclipse?

It looks as if you're getting class resolution errors in the Loader.
I'm not sure why this is happening, but I would guess that the class
loader is seeing the library classes in your test package, not your
main application. These classes may be out of sync with the classes
expected by the main application. Remember that in a test, you're
running both test and app in the same process, so the loader may not
try to load library classes twice.

Build the library into the main app and export the classes, and then
(I think this is right) make the test project dependent on the main
app but *not* the library project. I think that should work.
