Hello Ricard,
I tried it on Android but just one little error:
java.lang.IllegalArgumentException: already added: Lorg/apache/batik/svggen/font/Font;
The batikfont is duplicated in the geomerative.jar.
I just delete the batikfont.jar and it works.

Thank you for your work. That helps me a lot.
Greetings from Germany
