        It did; sorry for not getting back to you quickly.

        Great ! I -suspect- that the current state of LibreOffice on Android
may be more susceptible to an Accessible interface for blind users than
it is for a sighted user's 60fps smooth / tiled-rendering with
animations experience =)

        So - I think this is quite an achievable goal. The main development
would be around building a bridge between our UNO accessibility APIs and
the native Android a11y stack. Experience suggests that the size of one
of these bridges should be:

        atk:    2012 ';' LOC (git grep ';' | wc -l )
        IAcc2:  5000 ';' LOC

        So - really achievable =)

        Great.

        That is indeed annoying; perhaps the best person to talk to there would
be Tor; I'll set a build of master going on my local machine too though
for good measure.

        Hopefully you are running 'make' inside android/ to build that stuff ?
we have to pre-process & generate some compatible ant files - to turn
off compression for various assets in the .zip - if that is hosed (new
Android SDKs tend to bust that gratuitously) then we may need to fix
that. What SDK / NDK versions do you have ?

        It sounds awesome, welcome to the community; sorry for the initially
slow response; Tor if you could spare 30mins or so getting Keith going
over the next while that'd be lovely ! =)

        All the best,

                Michael.
