Android: During dw_file_browse() request read/write access to external
storage. Was hoping this would fix the file access problem in DWIB but sadly
it did not, however I still think we need this permission so leaving the
code changes. It also required updating the androidx libraries and adding
the activity library. After updating there were some reported code errors so
those are fixed in this commit as well.
