Download

This project contains OpenCV native libraries for every mobile architecture, which means that the APK is split into multiple ones to prevent a one big fat APK. You can install the application in one of two ways:

  1. Go to the releases and download the APK for your phone's architecture. If you don't know it, here is a nice article describing how to determine it. If don't have time to read the article, then arm64-v8a should be a safe bet.
  2. Clone the project and install it using Android Studio.
