For what it's worth, this still at least looks like it's mostly code from test frameworks, which doesn't necessarily even run on an Android device itself. So it could likely be dropped from the source distributions without compromising the functionality of any device. (Distributing it would still have been infringement --- but a lot more easily remedied than it might have been otherwise.)

Specifically, if we look at the PDFs from the original source here:

six of the seven Android files are in subpackages of "org.apache.harmony.security.tests". The Android version of Mueller's example number six, strangely, has no package declaration at all, but the name of the class (PolicyNodeImpl) at least is the same as one that has been identified as unit test code the last time it came up in this connection.

(BTW, the "org.apache.harmony" package prefix doesn't necessarily mean that the ASF ever distributed the particular file in question; that PolicyNodeImpl.java file was distributed by Google with an Apache Harmony package declaration, but had never been distributed by the ASF itself.)
