Looks like I’m going to have to work with OpenCV and android a lot in the near future.

  1. OpenCV in Android Studio
  2. SourceSets for jniLibs: To be used when the debug log says library not found.
  3. Initialization


  1. Get started with OpenCV on Android: Camera Capture, some image processing and conversion utility examples.
  2. OpenCV Java API: Official Documentation
  3. Drawing a line on custom view canvas: Contains solutions for cubic splines and stuff, to make the path look smooth.
