Unit testing Android application logic

Looking to write some tests for my application, I stumbled upon the Android testing pages. After a fairly long read, it quickly became apparent that the only thing that I could possibly get out of it is information about how to test the UI/Activities. What I really want is the way to test my logic with simply ant test, preferably without even involving the device. I should mention at this stage that I am not using Eclipse and it's quite saddening that 99% of the Java resources on Android assume people do so.

In any case, trying to get anything at all running, I played along with the tutorial as much as I could. It asks that a tests directory is made on the same level as src. Sure, even if every other of their pages implies that the test-project is a completely separate entity. While in the top level project directory, I ran android create test-project -m /path/to/my/project/ -n MyProjectTest -p tests. It's worth mentioning that they are very inconsistent with saying how they want things to be set up as seen on this question. Visiting the directory, I spot the default testing file. Here's where the issues begin.

To my understanding, testing is done as follows: build application, install; go to tests, build tests, install; run tests from the tests directory using ant test or start them directly using adb shell am instrument. This worked fine. I however have no desire to test the activity but just the logic (which doesn't access any Views/Activities).

Changing the default test to extend AndroidTestClass seemed to have work for a while. The tests were being ran but there were caveats: cleaning tests with ant clean also cleaned the project directory (../tests) so it took forever to build tests in a clean environment (which is necessary because ant debug seems terrible at detecting changes) but it worked and I was happy.

Few more tests later, I get java.lang.VerifyError on my only test class. Googling and Stacking around, it boiled down to either something wrong with external libs or something wrong with my class path. I'm not using any external .jars so it's probably my path.

In any case, here is my question: what is The Proper Way™ to unit test logic in Android applications with JUnit? I can't find any resources at all concerning this: all resources are either for testing the UI parts or for unit testing ordinary applications.

How can I unit test my logic only? This shouldn't even require a device to run on given that I don't need to use any parts of Android. Where do I place the tests? What do I need to change so that running ant test in my project directory will then run those?
