Frog is an Android app which lets you use an event-camera that is connected via USB to the phone. You can then parse the events with your own C++ code or use the Tarsier toolbox.
It's easiest to use Android Studio, for superb support of both Java and C++ code and the Gradle build tool. Alternatively, run gradlew clean build from the command line and install the .apk file under app/build/outputs/apk/release/ manually.
Java code is backed up by Robolectric. This does not include any C++ code for the moment.

Simply open up a pull request from your fork. This repo will stay free of actual C++ algorithms for the moment.
