1 gradle : Building Android Apps Mobel Meetup

2 Biography Working with Java since the dark ages at Progress Software, Alcatel-Lucent, Interested in science and technology Alex Van Boxel Software Architect - Vente-Exclusive.com

3 Build History a brief history of java build systems

4 In the beginning there was nothing

5 Bo ttl 20 ed i 00 n created Ant and he saw it as messy

6 Ant example <project> <target name="clean"> <delete dir="build"/> </target> <target name="compile"> <mkdir dir="build/classes"/> <javac srcdir="src" destdir="build/classes"/> </target> <target name="jar"> <mkdir dir="build/jar"/> <jar destfile="build/jar/helloworld.jar" basedir="build/classes"> <manifest> <attribute name="main-class" value="io.mobel.helloworld"/> </manifest> </jar> </target> <target name="run"> <java jar="build/jar/helloworld.jar" fork="true"/> </target> </project>

7 Bo ttl 20 ed i 01 n + created Maven and he saw it was better, but...

8 Maven example <project xmlns=" xmlns:xsi=" xsi:schemalocation=" <modelversion>4.0.0</modelversion> <groupid>com.mycompany.app</groupid> <artifactid>my-app</artifactid> <version>1.0-snapshot</version> <packaging>jar</packaging> <name>maven Quick Start Archetype</name> <url> <dependencies> <dependency> <groupid>junit</groupid> <artifactid>junit</artifactid> <version>4.8.2</version> <scope>test</scope> </dependency> </dependencies> </project>

9 Maven s build by convention my-app -- pom.xml `-- src -- main `-- java `-- com `-- mycompany `-- app `-- App.java `-- test `-- java `-- com `-- mycompany `-- app `-- AppTest.java

10 Bo ttl 20 ed i 11 n + created Gradle build files in XML is so 80 s

11 Out of the box features Declarative Syntax Build-By-Convention Task-graph Multi-Project Builds Dependency Power Tool Groovy

12 Android Build System = Gradle + Android Gradle Plugin + IDE integration

13 Why a new Build System Customizable and extensible but stable API Unified across IDE and CI Standard and Advanced features

14 One Build System to Rule them All Same build system from IDE, command-line and continuous-integration environment

15 Advanced Tool Interface API IDEA and Studio Command Line MobelDemoProject git:(master) gradle tasks :tasks All tasks runnable from root project Android tasks androiddependencies - Displays the Android dependencies of the project signingreport - Displays the signing info for each variant Build tasks assemble - Assembles all variants of all applications and secondary packages. assembledebug - Assembles all Debug builds assemblefreegoogleio - Assembles all builds for flavor FreeGoogleIO assemblefreegoogleiodebug - Assembles the Debug build for flavor FreeGoogleIO assemblefreegoogleiorelease - Assembles the Release build for flavor FreeGoogleIO assemblefreegoogleiostaging - Assembles the Staging build for flavor FreeGoogleIO TeamCity Others Eclipse Atlassian Bamboo Jenkins etc...

16 Advanced Tool Interface API Integrates with Android Studio based on IDEA or works in Eclipse with Android Plugin...

17 Declarative Domain Specific Language The Android plugin extends the Gradle DSL

18 Gradle Skelet buildscript { repositories { mavencentral() } dependencies { classpath 'com.android.tools.build:gradle:0.6.1' } } apply plugin: 'android' android { compilesdkversion 17 buildtoolsversion 18.1 }

19 Convention over Configuration my-app -- build.gradle `-- src -- main `-- java `-- test `-- java

20 Convention over Configuration my-app -- build.gradle `-- src -- main -- AndroidManifest.xml -- res -- assets -- aidl -- rs -- jni `-- java -- instrumentedtest -- res -- assets -- aidl -- rs -- jni `-- java `-- test `-- java

21 Gradle Tasks gradle <task> [<task>] gradle tasks [--all] assemble assemble the project(s) check run all the checks build assemble + check clean clean all the output

22 Build Variant = Build Types + Product Flavors

23 DSL: Build Types buildtypes { release { signingconfig signingconfigs.release } debug { packagenamesuffix ".debug" versionnamesuffix = ".D" debuggable true } staging.initwith(buildtypes.debug) staging { packagenamesuffix ".staging" buildconfig "private final static String server = \"staging.example.com\"" } }

24 DSL: Signing Configuration signingconfigs { release { storefile file("src/mobel.keystore") storepassword "mobelmobel" keyalias "release" keypassword "mobelmobel" } } buildtypes { release { signingconfig signingconfigs.release }

25 Convention over Configuration my-app -- build.gradle `-- src -- main -- AndroidManifest.xml -- res -- assets -- aidl -- rs -- jni `-- java -- debug staging instrumentedtest `-- test `-- java

26 DSL: Build Types debug release staging debug release staging

27 DSL: Product Flavor Example without groups productflavors { Mobel { } GoogleIO { } Example with groups flavorgroups 'version','session' productflavors { Mobel { flavorgroup 'session' } GoogleIO { flavorgroup 'session' } free { flavorgroup 'version' } paid { flavorgroup 'version' } }

29 DEMO

30 Stable Build Environment keep is stable...

31 Stable Build Environment Gradle version use the gradle-wrapper Plugin version dependencies { classpath 'com.android.tools.build:gradle:0.6.1' }

32 Stable Build Environment Build tools android { compilesdkversion 18 buildtoolsversion "18.1.0" IDE doesn t build your project

33 Testing unit- and integration testing in the same project

34 Test Code Generation Testing Sources Sets Standard test/ Android instrumentedtest(flavor)/ Generated Manifest Special APK for library projects

35 Testing Scenarios check connecteddevices devicecheck

36 Test Server API use the cloud for parallel testing

37 Testing Server API Control your lab Services from TestDroid Manymo AppThwack image from AppThwack website

38 Dependency Management flexible and reuse your current repo s

39 Dependencies dependencies { compile 'com.android.support:support-v4:18.0.+' compile 'com.android.support:appcompat-v7:18.0.+' compile 'com.google.android.gms:play-services:3.2.65' compile 'com.google.android.gtm:tagmanager:3.0.0' compile 'joda-time:joda-time:2.3' compile 'com.fasterxml.jackson.core:jackson-core:2.2.3' compile 'com.fasterxml.jackson.core:jackson-databind:2.2.3' compile 'com.google.guava:guava:15.0' compile 'com.squareup.dagger:dagger:1.1.0' compile 'com.squareup.dagger:dagger-compiler:1.1.0' compile(group: 'de.keyboardsurfer.android.widget', name: 'crouton', version: '1.8.1') { transitive = false } }
