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 !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'
