This document discusses Gradle and its use in Android Studio. It begins with defining Gradle as a build language, dependency manager, and task scheduler that uses Groovy for a build-by-convention approach. It then notes how Gradle makes it easy to create Android projects with multiple modules and build types/flavors in Android Studio. The rest of the document demonstrates Gradle's project structure and basics, use of plugins and tasks, and how to set up multi-module, build type, and flavor configurations to build different variants of an Android app in Gradle and Android Studio.

4. Gradle actually is …
 Your friend in Android Studio
 Makes it easy to create Android Projects that can handle multiple
modules (app , library, APIs)
 Allows you to use a single Android Project to develop versions for
 Production
 Demo
 Based on simple declarative and easy to express language
 Can be run from both command line and inside Android Studio
 And other goodies …
Maybe … this is beginning to make more sense.

5. Android Developers – Wake up !

Simply Import Eclipse projects or
Export to Gradle

8. Gradle + Android Studio – In Action
 Project Basics [settings.gradle, build.gradle
(proj+modules)]
 Plugins + Tasks + Convention = Magic
 Module Settings – UI into build.gradle
 Gradle Tasks – Command Line + Window
 Multi – Module Projects
 Build Types– Debug / Release
 Flavors – Demo / Full
 See another sample Project

9. Project Basics
9
• Project Root : settings.gradle,
build.gradle
• Module Root : build.gradle

10. Android Plugin
10
• apply plugin:
'com.android.application'• Android DSL

11. Module Settings
11
• Modify build.gradle OR
• Via Module Settings UI

12. Gradle Tasks
12
• Command Line
• Gradle Commander

13. Multi Module Projects
13
• settings.gradle at Root
• Each folder at root is a module
• build.gradle in each module
• specific plugins
• mention Dependencies
• Example : Android + Cloud Module

14. Build Types & Build Tasks
 assemble
 check
 build
 clean
14
 debug
 release

15. Product Flavors
 Allows you to build multiple variants of the same application
 demo
 full
 For e.g. 2 Config Types and 2 Flavors = 4 combinations
 demoRelease
 demoDebug
 fullRelease
 fullDebug
 Apply separate resources
 Apply separate source files
