The new Unit Tests feature in Android Studio fakes the entire Android SDK so that you can run fast, Java-only tests, without needing to install your application on an Android device (this is similar to Robolectric). The general idea is that you mock all the responses from the Android SDK calls.

AndroidTestCase is used to run a test with the real Android SDK.

So, your issue is that you are trying to run an AndroidTestCase that depends on the Android SDK, but your test runner is launching the Unit Tests environment, which uses a fake Android SDK instead of a real one.

You need to choose one approach. If you want a pure unit test, then you probably should use a JUnit 4 test class instead of an AndroidTestCase. More instructions here: https://developer.android.com/training/testing/unit-testing/local-unit-tests.html#build
