Prospects for an accessible and open version of Android?

     Termux has something called 'PROOT' that allows one to use a 
'chroot' environment in user space.  This in theory allows running Linux 

some Android phones by using Termux.

Some linux distributions such as Arch, Debian, and Ubuntu are listed in 
the TERMUX Wiki.

TERMUX is hard to use with TalkBack, but you can start it up.

Termux has an 'Espeak' package.  I was able to do a 'hello world' with 
it.  You can start an SSH daemon and work on it from another computer, 
but it would be necessary to port a text based screen reader into it as 
far as I can tell.  Like others said the Android GUI seems to be Java 
based, so I think people use a VNC client for the output of X Windows. I 
assume that would not be accessible, but somebody may know better.

If anybody has Brltty going on an Android device, you might try Termux 
and see if it can track the cursor.

However, the RasPi isn't a great starting point for a truly portable (i.e., palmtop) computer system.  Size and weight issues aside, there is the problem of how to support "instant on" capability (e.g., for use as a notetaker).

I haven't been able to find any reasonable way to get this kind of behavior on a RasPi.  Even idling, the power requirement over a day would drain any reasonable set of batteries.  Booting the device and shutting it down each time I want to use it would be very inconvenient.
> A few billion Android cell phones have been manufactured and more are being made all the time.  After a few years, these get really cheap to buy, because the latest version of Android won't run on them.  So, why not repurpose them as blind-friendly computers, notetakers, etc?
