One question. Do you need this dependency tree?

--- App
   |--- Library 2
   |--- Library 1
       |--- Library 3
       |--- Library 4

If yes, your App does not need import the libraries 3 and 4. These dependencies are available over the Library 1.

About settings.gradle files. Why one in each module? This file is only used in the root project (like Eclipse workspace) to reference your modules (App, Library 1, Library 2, etc...)

This help you?
