Gradle tip - Set names to your modules

Set names to your modules/sub-projects. The name for your module/sub-project will be defined according to the filesystem directory it's in. You can change naming for better readability later on, using:

include ':SDK'
project(':SDK').projectDir = new File('MySdkProjectDirectory/')

Gradle tip - Leverage a top-level build.gradle

Usually a project contains more than one sub project or module. In that case you will want to have common settings that will be shared among them, saving you the trouble of rewriting them or maintaining future changes. A common setting will be the Android's buildscript dependency - classpath 'com.android.tools.build:gradle:x.y.z'
