1. Start the IDE with a fresh userdir (I did this by building from sources in NetBeans and running the suite from NB)
2. Create an Android project
The project shows unresolved references: JUnit libraries. This is because the Java kit is not activated, and the library manager is not populated. The workaround is to create a Java SE project - this enables the Java development features. The fix could be e.g. to have a dependency of the Android suite on java.kit.
Hmm, works for me. Can it be related to use of ergonomics (that I turned off)?
