Launcher3 Architecture, libgooglefeed, and Custom -1 Screen

Android Launcher3 is a very interesting system application, and is an application that a user interacts to the most in every aspect of their smartphones, starting from unlocking the device/opening an app/closing an app, or interacting with other UX aspects. Launcher3 is architectured in a very interesting way, been working on the app project for over a year and I reversed a lot of interesting discoveries, regarding libgooglefeed, that hooks google search to -1 screen, that is displayed is most of default launchers in smartphones.
