10.6/master has a lot more features (ie. significant chunk of
gl3/gles3), but I think 10.4 should be fine for getting android up and
running.  For a4xx I recommend 10.5 or master, but a3xx support has
been around a lot longer.  Do keep in mind that master now wants NIR,
not sure if that is missing from android build files.

So I think from my perspective, either of 10.4/10.5/master should be
fine.. just start with whatever is easiest from android build
perspective.
