Thanks to Oracle's lawyers, it's necessary to observe that Android doesn't run "Java", it runs Dalvik.
Regardless, the Android platform. while more extensive than JME, is still not a 100% implementation of the desktop edition of Java, much less the desktop/enterprise JDK.
It might make an amusing project, but personally, I'd rather see Tomcat on one of the "wall-wart" computers and leave the Galaxy for browsing.
Although I'll admit I'd be tickled if I could run OS/MVS on my cellphone (Project Hercules).
The secret of how to be miserable is to constantly expect things are going to happen the way that they are "supposed" to happen.
You can have faith, which carries the understanding that you may be disappointed. Then there's being a willfully-blind idiot, which virtually guarantees it.
