Extension: !Automatische Versions-Verwaltung !

Ziel: !"Version Code !"Version Name !"- einfach konfigurierbar halten !"- aus git-tags extrahieren und in gradle setzen !"!"Build-Informationen in der App verfügbar machen: !" "- Build-HOST !" "- Build-TIME !

!!


Automatische Versions-Verwaltung !

Schritt 1: !!Build-Informationen in App anzeigen !!

" "Build-Time !" "Build-Host !"!

über BuildConfig!



Schritt 2: !!Konfiguration von !!

" "Version Code !"!

über eine Property-Datei !



Schritt 3: !!Berechnung von versionCode und versionName!!

"version=2.1.3 !!

"versionCode=2130 !"VersionName=2.1.3 !



Schritt 4: !!Versionsnummer aus git Tag auslesen !!

" "git-Tag „2.1.3“ !!



Schritt 5: !!Versionsnummer + App Name dem APK hinzufügen !!<name>-<sub-name>-<buildType>-<version>.apk!



Modularisieren: !!inside build-scripts!!buildSrc/ !!external build-scripts (local file or http) !apply from:'https://raw.github.com/../all-jars.gradle‘ !apply from:'~/.gradle/RobertFischer/gradle-scripts/all-jars.gradle‘ !!via dependencies / Repository !

Key Features !

•  Layout Editor !

•  IntelliJ Features !

•  Improved Checks !

•  Improved UI !

•  ... !!!!

Status Quo !

•  Mostly stable but expect breaking changes!

•  Documentation poor!

•  Many examples might not work (old versions) !

•  Features are worth considering it

•  Mostly stable!

•  Unpredictable updates!

•  Tools & Features missing!

•  IntelliJ EAP Release

Empfehlung !

•  „I‘m feeling lucky“ !

•  Multiproject-Builds!

•  Safe side: stay with eclipse (but maybe use gradle) !

•  Gradle will be mandatory / Android Studio is optional !

Tipps + Tricks !

Tipps + Tricks !Gradle daemon

$> cat .gradle/gradle.properties

org.gradle.daemon=true

org.gradle.jvmargs=-‐Xmx2048m

-‐XX:MaxPermSize=512m

-‐Dfile.encoding=UTF-‐8

Show dependencies

$> gradle dependencies

Tipps + Tricks !Gradle Init Scripts $> cat .gradle/init.gradle initscript { allprojects {

apply plugin: 'maven’ repositories { maven { url = "http://archiva.inovex.de:8080/archiva/repository/snapshots/" } } } }

Tipps + Tricks !Gradle Wrapper

./gradlew Instead of gradle Initialize with: task wrapper (type: Wrapper) {

gradleVersion = “1.11” }

Tipps + Tricks !Android-SDK-PlugIn - Like the wrapper but for the SDK

dependencies { classpath 'com.android.tools.build:gradle:0.10.+' classpath 'com.jakewharton.sdkmanager:gradle-‐plugin:0.9.1‘ } apply plugin: 'android-‐sdk-‐manager’ apply plugin: 'android'

$> gradle assembleDebug -‐-‐profile

DANKE!
