First, we need to decide whether we indeed want to have this in Emacs.
Android is not a free platform, so when its support comes with a lot
of additional non-trivial code that we'd need to understand and
support/maintain (including a lot of Java), we had better discussed
that first.

If we do decide to have this, I'd definitely want more documentation
of the internals and how they differ from the "traditional" platforms
than you have there now, and preferably in one place, not scattered
among the many source files, Makefile's, and READMEs.

Then there are the design decisions you made: how to support windows
and frames, how to handle the "task-killer" issues, how to handle the
Android's access rights and privileges system, etc.  For instance, I
was quite surprised to see lack of support for scroll bars on account
of them being "useless": I'm a happy user of an Android smartphone,
and I use the scroll bars all the time.

If we are to have a serious discussion of this, I'd encourage people
to read the code of the branch and bring up issues here.
