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 !
