Getting waaayyyy off topic here, but...

I guess you aren't familiar with what Android is (which is ironic, given
that a lot of people on this list think you must be one!).  Android is
not simply a customized linux distribution.  It's a special application
environment (an OS in its own right) that is based on the Dalvik virtual
machine.  Dalvik does depend on the Linux kernel to talk to the
hardware, but Linux very much is not a part of Android, at least from
the developers' and end users' points of view.  Linux is just not a part
of the user experience at all.  It is true that Dalvik can call into
native linux code, but native linux applications typically aren't a part
of the Android user experience.

Thus you can't just install any JVM on android.  Thus cpython or jython
just isn't part of it.  For one I don't know of any sun-compatible JVM
that has been ported to ARM.  For two, there aren't any hooks into the
Android UI APIs even if you could get it running.

Android is even being ported to the QNX kernel by the Blackberry folks,
so they can have android compatibility on next-generation blackberries
that run their own native OS.

I do not understand what you are saying, or at least why you are saying
this.  But I don't understand most of your posts.
