I have a complicated image processing script that runs in python with Numpy and OpenCV. I want to run this script in Android but I couldn't find a way to do it.

After some research I found some frameworks that may help but I have some problems with them:

  • Kivy only generates full APK, but what I need is an AAR or some background service so I could use it from other apps
  • QPython only runs scripts, I didn't find a way to communicate with it from my app
  • cxfreeze I've tried to generate executable out of my script and then running it from my app, but I couldn't find a way to compile my script to an ARM processor so Android would be able to execute it

I will be happy to hear some ideas on how to run this script in Android. Is it possible to maybe root the device and install Python, Numpy and OpenCV?

The best solution for me was using steveliles's OpenCv for Android and converting the Python scripts to Java. Turns out opencv had all the mat calculation functions I needed

Another solution would be using chroot: https://technohackerblog.blogspot.co.il/2016/07/running-arch-linux-in-chroot-on-android.html
