Android Camera2 Touch-to-Focus

I've scanned SO for a way to get touch-to-focus to work on Android and could not find a solution that works.
These were very partial, or provided only scaffold code which I couldn't use:

My first Thing on Thingiverse!

2017-02-17 09.18.33
Just wanted to share the first Thing I uploaded to Thingiverse (which is a huge open-source collection of 3D-printable or otherwise fabricateable objects).

It's a 1/4-20 (standard camera mount) holder for a smartphone using a rubber band.
I saw many designs that use screws to hold the phone in place, but I didn't have such screws and I had many loose rubber bands. Also a rubber band allows the phone to snap in and out more easily.

It's a very basic 3D design I did with FreeCAD, then made it on my FlashForge Creator Pro.

Enjoy
