3. Eclipse / Ant Maven Gradle Android Build System
5. Single Build System Build from command line or your IDE Default folder structure Tasks for build, test, install,...
6. Simplify AndroidManifest Version code and version name Package identifier Minimum and target sdk Placeholder support
7. Build Types Debug, release and your owns Add application id and name suffixes Signing Configurations Running proguard
8. Dependency Management Local packages Build type specific dependency No need to distribute the dependencies Multi project support
10. 1 android { 2 compileSdkVersion 19 3 buildToolsVersion '19.0.0' 4 5 defaultConfig { 6 applicationId 'com.example.app' 7 versionCode 12 8 versionName '2.0' 9 minSdkVersion 16 11 targetSdkVersion 16 12 } 13 } Simplify Manifest
11. 1 android { 2 buildTypes { 3 debug { 4 applicationIdSuffix '.debug' 5 versionNameSuffix '-debug' 6 } 7 release { 8 runProguard true 9 proguardFiles 'file1.pro', 'file2.pro' 10 signingConfig signingConfigs.mySignConfig 11 } 12 } 13 } Build Types
12. 1 android { 2 signingConfigs { 3 mySignConfig { 4 storeFile = file(project.property('file')) 5 storePassword = project.property('password') 6 keyAlias = project.property('keyAlias') 7 keyPassword = project.property('keyPassword') 8 // Command line or environment variable 9 // System.console().readLine("\n\$ Password: ") 10 // System.getenv("KEYSTORE") 11 } 12 } 13 } Signing Config
13. 1 dependencies { 2 // All jar in libs folder 3 compile fileTree(dir: 'libs', include: ['*.jar']) 4 // Dependency from repository 5 compile 'com.android.support:support-v4:20.0.0' 6 // Library project in same folder 7 compile project(':library-project') 8 // Dependency for release build 9 releaseCompile 'com.google.code.gson:gson:2.3' 10 } Dependencies
15. Flavors Application variants Same type as the android.defaultConfig Flavor specific dependencies Build Type + Product Flavor = Build Variant
16. Multi-Flavors Distinct dimensions Flavors are assigned to a specific dimension Combine dimensions to create de app
17. 1 flavorDimensions 'type', 'store' 2 productFlavors { 3 full { 4 flavorDimension 'type' 5 } 6 lite { 7 flavorDimension 'type' 8 } 9 amazon { 10 flavorDimension 'store' 11 } 12 play { 13 flavorDimension 'store' 14 } Flavors fullAmazonDebug fullAmazonRelease liteAmazonDebug liteAmazonRelease fullPlayDebug fullPlayRelease litePlayDebug litePlayRelease
18. Source Sets Build Types and Product Flavors have their own sourceSet src/main, src/<buildType1>, src/<flavor1>,... Source code (src/*/java) generate a single output Manifests are all merged Resources using priority: BuildType > Flavor > Main
19. 1 <manifest> 2 <application> 3 <activity> 4 <!-- --> 5 </activity> 6 </application> 7 </manifest> Manifest Merge 1 <manifest> 2 <uses-permission> 3 </manifest> 1 <manifest> 2 <uses-permission> 3 <application> 4 <activity> 5 <!-- --> 6 </activity> 7 </application> 8 </manifest> 1 2 3
20. Gradle + Android Studio
21. Android Studio vs Eclipse AS Eclipse Build system Gradle Ant Maven-based build dependencies Yes No Build variants and multiple-APK generation Yes No Advanced Android code completion and refactoring Yes No Graphical layout editor Yes Yes APK signing and keystore management Yes Yes NDK support Soon Yes
22. Some Features An IDE built for Android Gradle integration IntelliJ IDEA is the base for Android Studio Preview resources (drawables, strings,...) Advanced layout editor (includes, xml drawables) Templates
