NFD » NFD-android

After building NFD-android from source master branch with no changes, the debug APK is deployed to my device without and is started automatically. It crashes every time with the below error. This is where it is trying to load "all shared library dependencies that are located in app's lib folder". I can see there is no app/src/main/libs folder in the source code however according to this tutorial (https://named-data.net/tutorials/milcom2017/milcom2017-ndn-3-codebase.pdf) page 7, the folder and ultimately the missing libnfd-wrapper.so file should exist. What is going wrong here?
