Could be. :-)

Does not require it, as far as I know. I only put in 16 as the default
because it's the SDK platform that I have installed on my machine. The
gist of what's going on there is this:

The MeshTether app wants to be notified using an Android Handler object.
To include the ability for the fork Java API to include this
functionality and build properly, it has to "link" against android.jar.
(At least that's the way I understand it.) So, as a default I used what
I had defined on my system and that was 16. The Android Handler has been
in the API since version 1
(http://developer.android.com/reference/android/os/Handler.html) so it
should work on any platform.

I hope I made that clearer rather than, well, vaguer, if that's even a word.

That was only commented out because it does not work on the specific
device that I am using for testing. Sorry for allowing that to slip through.

Please reach out with other questions. I am interested in your feedback,
as always!
