mixite: Cannot use the library in Android

When using hexameter in Android I receive the error message:

`AGPBI: {“kind”:“error”,“text”:“trouble processing "javax/xml/parsers/DocumentBuilder.class":”,“sources”:[{}]}

AGPBI: {“kind”:“error”,“text”:“Ill-advised or mistaken usage of a core class (java.* or javax.*)”,“sources”:[{}]}

… and so on.

That dependency of a core class is somewhere in hexameter-core. I use the version 3.0.0 of that library.
