1. @devisnik #AndroidBuild Level Up Your Android Build Volker Leck, Novoda, Berlin
2. @devisnik #AndroidBuild Getting started
3. @devisnik #AndroidBuild app/build.gradle apply plugin: 'com.android.application' android { compileSdkVersion 22 buildToolsVersion '22.2.0' defaultConfig { ... } buildTypes { release { ... } } } dependencies { ... }
4. @devisnik #AndroidBuild Relevant Build Files ├── app │ └── build.gradle ├── build.gradle ├── gradle │ └── wrapper │ ├── gradle-wrapper.jar │ └── gradle-wrapper.properties ├── gradle.properties ├── gradlew ├── gradlew.bat ├── local.properties └── settings.gradle
5. @devisnik #AndroidBuild Gradle wrapper $ ./gradlew tasks
6. @devisnik #AndroidBuild Gradle wrapper $ gw clean ass
7. @devisnik #AndroidBuild Using a Gradle plugin /build.gradle buildscript { repositories { jcenter() } dependencies { classpath 'com.android.tools.build:gradle:1.2.3' classpath 'com.novoda:gradle-android-command-plugin:1.4.0' } } /app/build.gradle apply plugin: 'com.novoda.android-command' $ gw runDebug
8. @devisnik #AndroidBuild Dependencies dependencies { compile 'com.google.guava:guava:18.0' testCompile 'junit:junit:4.12' testCompile 'org.mockito:mockito-core:1.9.5' }
9. @devisnik #AndroidBuild Dependencies apply plugin: 'com.neenbedankt.android-apt' dependencies { apt 'com.google.dagger:dagger-compiler:2.0' compile 'com.google.dagger:dagger:2.0' compile 'com.google.guava:guava:18.0' testCompile 'junit:junit:4.12' testCompile 'org.mockito:mockito-core:1.9.5' }

11. @devisnik #AndroidBuild Proguard
12. @devisnik #AndroidBuild Proguard buildTypes { release { minifyEnabled true shrinkResources true proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard.cfg' } } proguard.cfg #Dagger2 -dontwarn dagger.shaded.auto.common.** -dontwarn dagger.internal.codegen.** -keepattributes Signature
13. @devisnik #AndroidBuild Archive Release ext.VERSION_NAME=1.0.0 ... task archiveRelease(type: Copy) { from 'build/outputs/apk', 'build/outputs/' into "releases/${VERSION_CODE}" include('android-release.apk', 'mapping/**') rename ('android-release.apk', "${APP_NAME}_${BUILD_DATE}_${VERSION_NAME}_${VERSION_CODE}.apk") }
14. @devisnik #AndroidBuild Udacity course
15. @devisnik #AndroidBuild First Success
16. @devisnik #AndroidBuild Scaling up • re-use • testing • quality assurance • continuous integration • push-button release
17. @devisnik #AndroidBuild Re-use - Core project gradle init --type java-library dependencies { compile project(':model') }
18. @devisnik #AndroidBuild gradle init --type java-library dependencies { compile project(':model') } gradle init --type groovy-library def url = new URL('https://api.github.com/users/devisnik/starred') def json = new JsonSlurper().parseText(url.text) println json*.name Re-use - Playground project
19. @devisnik #AndroidBuild Testing - Integration Tests in Core sourceSets { integrationTest { java { srcDir 'src/integrationtest/java' } resources { srcDir 'src/integrationtest/resources' } compileClasspath += sourceSets.main.runtimeClasspath } } task integrationTest(type: Test) { testClassesDir = sourceSets.integrationTest.output.classesDir classpath += sourceSets.integrationTest.runtimeClasspath }
20. @devisnik #AndroidBuild Keeping Up To Date apply plugin: 'com.github.ben-manes.versions' $ gw dependencyUpdates The following dependencies have later milestone versions: - com.fasterxml.jackson.core:jackson-annotations [2.1.2 -> 2.6.0- rc1] - com.fasterxml.jackson.core:jackson-core [2.1.1 -> 2.6.0-rc1] - com.fasterxml.jackson.core:jackson-databind [2.1.2 -> 2.6.0-rc1] - com.github.kevinsawicki:http-request [4.0 -> 9.9] - joda-time:joda-time [2.3 -> 2.8] - org.mockito:mockito-core [1.9.0 -> 2.0.8-beta] Generated report file build/dependencyUpdates/report.txt

24. @devisnik #AndroidBuild Continuous Integration System.getenv("...") Jenkins BUILD_NUMBER Travis TRAVIS_BUILD_NUMBER
25. @devisnik #AndroidBuild Updating the Android SDK apply plugin: 'android-sdk-manager' $ gw assembleDebug Android SDK not found.

26. @devisnik #AndroidBuild Connected Tests on CI task filterTestDevices << { com.android.builder.testing. ConnectedDeviceProvider.metaClass .getDevices = { localDevices .findAll { it.iDevice.online } .findAll { !it.getProperty('ro.build.characteristics') ?.toLowerCase()?.contains('tablet') } .unique { it.apiLevel } } }
27. @devisnik #AndroidBuild Connected Tests on CI afterEvaluate { project.tasks.findAll { it.name.startsWith('connectedAndroidTest') }*.dependsOn filterTestDevices }
28. @devisnik #AndroidBuild Releasing from CI • update Version • commit changes • upload to Stores
29. @devisnik #AndroidBuild Release from CI - Versioning def versionFile = file('version.properties') Version version = Version.read(versionFile) task incrementVersion << { Version.increment(versionFile) }
30. @devisnik #AndroidBuild Release from CI - Versioning def versionFile = file('version.properties') Version version = Version.read(versionFile) task incrementVersion << { Version.increment(versionFile) } buildSrc └── src └── main └── groovy └── Version.groovy
31. @devisnik #AndroidBuild Release from CI - git buildscript { dependencies { classpath 'org.ajoberstar:grgit:1.1.0' } } ext { git = org.ajoberstar.grgit.Grgit.open( rootProject.file('.')) } def sha = git.head().abbreviatedId git.add 'version.properties' git.commit(message: "Bumping version to $VERSION_CODE") git.push()

42. @devisnik #AndroidBuild Sqlite Access code.template package $packageName; public final class $className { public static final class Tables { <% access.tables.each { dataSet -> %> public static final String $dataSet.name = "$dataSet. sqlName"; <% } %> } ... }
43. @devisnik #AndroidBuild Groovy on Android buildscript { repositories { jcenter() } dependencies { classpath 'com.android.tools.build:gradle:1.1.0' classpath 'org.codehaus.groovy:gradle-groovy-android-plugin:0.3.6' } } apply plugin: 'groovyx.grooid.groovy-android' dependencies { compile 'org.codehaus.groovy:groovy:2.4.3:grooid' }
