This repository (Android Studio project) is an implementation of @Mert-Şimşek's tutorial on medium.com about annotation processing in Java (and Android) that is created with a more recent version of Android Studio (v3.2), Gradle (v4.6), plug-ins and libraries (almost most recent at the time the repository created/updated: Oct 18, 2018). Thank he.
