ID Android TechTalk Series #6 : Google Service and Gradle - Anton Nurdin Tuhadiansyah
- 1. Anton Nurdin T Senior Software Engineer, Xendit anton46.com DEEP UNDERSTANDING ABOUT
- 8. Why Gradle? 1. Powerful Build System - Declarative, Flexible - Imperative Customization - Tooling API 2. Build System Toolkit - Plugins create own DSL, APIs, IDE integration 3. Free/Open Source
- 10. Structure Settings File - settings.gradle Top-level Build File
- 11. Top-level Build File buildscript { repositories { jcenter() } dependencies { classpath 'com.android.tools.build:gradle:2.0.0' } } allprojects { repositories { jcenter() } } build.gradle
- 12. Structure Settings File - settings.gradle Top-level Build File
- 13. Structure Settings File - settings.gradle Top-level Build File Module-level Build File
- 14. apply plugin: 'com.android.application' android { compileSdkVersion 23 buildToolsVersion "23.0.3" defaultConfig { ... } buildTypes { ... } productFlavors { ... } } dependencies { ... } Module-level Build File build.gradle
- 15. Gradle Tasks assemble check build clean assemble + check assembleDebug + assembleRelease connectedCheck deviceCheck
- 16. COSTUMIZATION
- 17. Basic Customization android { compileSdkVersion 23 buildToolsVersion "23.0.3" defaultConfig { minSdkVersion 15 targetSdkVersion 23 versionCode 1 versionName "1.0" } } build.gradle
- 18. Basic Customization def getVersionCode() { def code = ... return code; } android { defaultConfig { versionCode getVersionCode() ... } } build.gradle
- 19. Basic Customization android { defaultConfig { applicationId “com.example.app” minSdkVersion 15 targetSdkVersion 23 versionCode 1 versionName "1.0" applicationVariants.all { variant -> variant.outputs.each { output -> def file = output.outputFile def fileName = file.name.replace(".apk", "-v" + versionName + "-c" + versionCode + ".apk") output.outputFile = new File(file.parentFile, fileName) } } } } build.gradle
- 21. Build Types - Build / Packaging customization • Debuggable flag • ProGuard • Signing Configuration • Source / Resource Overlay - Debug and release prebuilt
- 22. Build Types android { buildTypes { debug { applicationIdSuffix '.debug' versionNameSuffix '-DEBUG' } beta { applicationIdSuffix '.beta' versionNameSuffix '-BETA' } } } build.gradle
- 23. Build Types : Source Folder src/main/AndroidManifest.xml src/main/java src/main/resource src/main/res src/main/assets src/main/aidl src/main/rs src/main/jni src/debug/... src/release/... src/beta/... src/androidTest/java src/androidTest/resource src/androidTest/res src/androidTest/assets src/androidTest/aidl src/androidTest/rs src/androidTest/jni
- 24. Gradle Tasks assemble check build clean assemble + check assembleDebug + assembleRelease + assembleBeta connectedCheck deviceCheck
- 25. Signing Configuration android { signingConfigs { release { storeFile file('<name>.keystore') keyAlias 'keyAlias' keyPassword 'keyPassword' storePassword 'storePassword' } } } build.gradle
- 26. Debuggable Release Builds android { signingConfigs { debugRelease.intiWith(buildTypes.release) debugRelease { debuggable true applicationIdSuffix '.debugrelease' signingConfig signingConfigs.debug } } } build.gradle
- 27. DEPENDENCIES

- 29. Dependency Scope: Android Projects compile runtime testCompile testRuntime compile package androidTestCompile androidTestPackage
- 30. Local Dependencies android { ... } dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) } build.gradle
- 31. Remote Dependencies repositories { jcenter() } android { ... } dependencies { compile 'com.android.support:appcompat-v7:23.2.1' } build.gradle
- 32. Multi-Project Setup settings.gradle include ':app' include ':libraries:lib1' include ':libraries:lib2' MyProject/ | settings.gradle + app/ | build.gradle + libraries/ + lib1/ | build.gradle + lib2/ | build.gradle
- 33. Project Dependencies android { ... } dependencies { compile project(‘:libraries:lib1’) } build.gradle
- 34. Android Library Project apply plugin: 'com.android.library' android { compileSdkVersion 23 buildToolsVersion '23.0.1' } build.gradle
- 35. Android Library - Binary Bundle (.aar) • Uploadable to repositories - Support for • assets • Proguard rules • Custom Lint rules • . . .
- 36. BUILD VARIANTS
- 37. Product Flavors - Different versions of the same application • Paid vs Free • Multi-APK support in Google Play - Different Dimension(s) than BuildTypes
- 38. Android Library Project android { productFlavors { flavour1 { applicationId "com.example.flavour1" minSdkVersion 16 } flavour2 { applicationId "com.example.flavour2" } } } build.gradle
- 39. Build Types : Source Folder src/main/AndroidManifest.xml src/main/java src/main/resource src/main/res src/main/assets src/main/aidl src/main/rs src/main/jni src/androidTest/java src/androidTest/resource src/androidTest/res src/androidTest/assets src/androidTest/aidl src/androidTest/rs src/androidTest/jni src/debug/... src/release/... src/beta/... src/flavor1/... src/androidTestFlavor1/...
- 40. Variant = Build Type + Product Flavor(s) No Flavors : debug release - debug release - - -
- 41. Variant = Build Type + Product Flavor(s) No Flavors : debug release - debug release - - - With Flavors : debug release Flavor1 Flavor1Debug Flavor1Release Flavor2 Flavor2Debug Flavor2Release
- 42. Build Variants : Source Code Multiple source folders, single output src/main/java src/debug/java src/free/java
- 43. Build Variants : Resource Overlays src/main/res src/debug/res src/free/res
- 44. Build Variants : Signing Configuration Priority Order android.defaultConfig.signingConfig android.buildTypes.release.signingConfig android.productFlavors.free.signingConfig
- 45. Build Variants : Package Name Overlays + Suffix android.defaultConfig.packageName android.productFlavors.free.signingConfig + android.buildTypes.debug.packageNameSuffix src/main/AndroidManifest.xml
- 46. Build Variants : Proguard android { ... buildTypes { release { minifyEnabled true proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } productFlavors { flavor2 { proguardFile 'flavor2-rules.pro' } } } build.gradle
- 47. Res / Code Generation buildConfigField resValue
- 48. build.gradle android { buildTypes { debug { buildConfigField "String", "SERVER_URL", '"http://staging.example.co"' resValue "string", "facebook_app_id", '"12345678910' ... } release { buildConfigField "String", "SERVER_URL", '"https://example.co"' resValue "string", "facebook_app_id", '"0987654321' ... } } } Res / Code Generation

- 57. Hint • Enable the Gradle daemon and parallel build dexOptions { incremental true } • Incremental dexing ~/.gradle/gradle.properties org.gradle.daemon=true org.gradle.parallel=true org.gradle.jvmargs=-Xmx1024m org.gradle.java.home=/path/to/jvm • Offline Mode • Separate project into modules
