unit testing - Can't build and run an android test project created using "ant create test-project" when tested project has jars in libs directory

Question

I have a module that builds an app called MyApp. I have another that builds some testcases for that app, called MyAppTests. They both build their own APKs, and they both work fine from within my IDE. I'd like to build them using ant so that I can take advantage of continuous integration.

Building the app module works fine. I'm having difficulty getting the Test module to compile and run.

Using Christopher's tip from a previous question, I used android create test-project -p MyAppTests -m ../MyApp -n MyAppTests to create the necessary build files to build and run my test project. This seems to work great (once I remove an unnecessary test case that it constructed for me and revert my AndroidManifest.xml to the one I was using before it got replaced by android create), but I have two problems.

The first problem: The project doesn't compile because it's missing libraries.

If you use Eclipse, a simpler approach is to not include your external library in the test project, but rather export it in the Eclipse Project settings. This will solve the issue

Time ago, I wrote a blog post explaining this: http://juristr.com/blog/2010/06/android-instrumentation-test/
