This document provides an introduction to using Gradle with Android Studio. It discusses the benefits of Gradle such as its Groovy-based syntax and improved dependency management. It also covers how to convert an existing Android project to use Gradle, adding build types and product flavors to create multiple APK variants, defining custom tasks, and setting up testing and continuous integration with Jenkins.
Gradle & Android Studio - Introduction
- 1. Gradle & Android Studio An introduction
- 3. Schedule ● ● ● ● ● ● Why Gradle? Converting an existing project Build types and product flavors Custom tasks Testing Continuous integration
- 4. Why Gradle?
- 5. Pros ● Not Ant ● Groovy-based ● Gradle wrapper ● Multi-project builds ● Dependency management
- 6. Cons ● Slower than Ant ● Documentation ● Android plugin under development ● Dependency management
- 7. Demo - New project
- 9. How to convert ● Project structure ● Gradle wrapper ● Dependencies Good resource: http://ryanharter.com/blog/2013/07/17/migrating-android-projects-to-gradle
- 10. Types & flavors
- 11. Build types ● E.g. debug, staging, production ● Separate packages ● Different resources
- 12. Build types - Example buildTypes { staging { packageNameSuffix ".staging" versionNameSuffix "-staging" signingConfig signingConfigs.staging } }
- 13. Build types - Example signingConfigs { staging { storeFile file("staging.keystore") storePassword "storepwd" keyAlias "alias" keyPassword "keypwd" } }
- 14. Build types - Example module src staging java res AndroidManifest.xml
- 15. Product flavors ● E.g. free, pro ● Multi APK (e.g. <= 2.2 & > 2.2) ● Combination Setup: same as build types
- 16. Build variants Build type + Product flavor = Build variant ● Pro Debug & Free Debug ● Pro Staging & Free Staging ● ...
- 17. Custom tasks
- 18. Custom tasks - Example task keyStorePassword << { def keystorePw = new String( System.console().readPassword ("Password?")) android.signingConfigs.release .storePassword = keystorePw }
- 19. Custom tasks - Example tasks.whenTaskAdded { task -> if (task.name.equals("packageRelease")) { task.dependsOn "keyStorePassword" } }
- 20. Testing
- 21. Instrumentation tests ● No separate project ○ srcinstrumentTest ● Own dependencies ○ dependencies { instrumentTestCompile x } ● gradlew connectedInstrumentTest
- 22. Unit tests (JUnit & Robolectric) ● No official support ● Add custom task ● Some hacking required
- 24. CI with Jenkins ● Android SDK on build server ● Gradle plugin - “Invoke Gradle script” ● Emulator support Good resource: http://blog.zuehlke.com/configure-your-android-project-on-jenkins/
