My application is seperated into three projects in eclipse.
The first one is a client Android Project called "Project A".
The second is a server Android Project called "ProjectB".
Lastly, I have "ProjectATest" for testing that has references
dependencies to "ProjectA" and "ProjectB".

When excuting InstrumentationTestRunner in "ProjectATest," I get the
following error message:

[2009-10-08 13:11:47 - ProjectATest]Launching instrumentation
android.test.InstrumentationTestRunner on device emulator-5554
[2009-10-08 13:12:01 - ProjectATest]Test run failed: cross-loader
access from pre-verified class

This is the error as pulled from LogCat:

I'm not sure what that exact error message means, but my guess is the
problem has to do with your test to project mapping. An
instrumentation (which is what your test project uses to access
classes in your project under test), can only be targeted to one
android application. Try splitting up your test project into
ProjectATest and ProjectBTest, and see if that helps.

Regards,
Brett.

I get this error as well, I believe it depends on the order of imports
within your test project. If you have lib1 added to both the test and
tested project, you ll get something of that sort.... Still trying to
sort it out.

Exactly...

Let me give you my example (and you can extrapolate it to your
situation)

I had project B that depends on project A (a set of exception classes
exported as an external jar)
Android Test project C called classes in project B and raised expected
exceptions defined in project A (depending on project A as an external
jar) which caught (as negative tests)

When I ran these tests (as Android JUnit tests) I got the same (cross-
loader) error

I removed external jar dependency of A from project C and everything
ran perfectly after that

Regards

Ty

Thank you everyone for your replies.

I was able to resolve this error. As hinted above, the problem lied in
my project settings.
In my test project, instead of referencing project B directly, I was
able to export the class files from project A.
(Under the "Order and Export" tab in the "Java Build Path" pane.)

This gave me access to all the classes I needed in my test project.

Thanks again for everyone's help.
