According to here:
there is sl4a / PythonForAndroid, unfortunately, it uses hardcoded java rmi invocations for anything os related. so - no opencv bindings there ;(
i guess, you'll have to learn java.

Also, although further dated, this still open issue on github leads me to believe that there is still no Python-Android OpenCV implementation.
There is no camera implementation in Kivy right now. And we never said than opencv was available on python-for-android too.
But there is hope for the future:
I have a plan of writing a recipe for it, not now, currently I am
quite overwhelmed by others ;-)

QUIK EDIT:
Lol, there is a working implementation on the open issue, it just doesn't have a nice recipe:
Here I attach the Eclipse project I have made to build libcv2.so for
Python on Android. It is a little bit messy because I really had a
headache working it out, and I'm short on time right now. Just import
it into Eclipse (I use ADT 22.0 and NDK r9c) and it should compile. I
took libopencv_java.so into the project so it shall be a dependency.
Also libpython2.7.so is a dependency too. If anyone can make this
into a Python for Android recipe then that would be awesome.
