So I wanted to try the new Android Studio and imported my eclipse projects (I generated a gradle build file). Worked pretty good.
The only library which does not seem to work is AndroidAnnotations. I selected the androidannotations-2.7.jar file under File > Settings > Compiler > Annotation Processing.
As production source directory i selected "gen". But the generated file like MainActivity_ are not generated. What did I wrong?
I had the same issues, followed the instructions for configuring aa with intelliJ, now it works like a charm does.
AA intelliJ config page will point you to this post...
...the above post walks you through setting up various libs in intelliJ, scroll towards the bottom for AA.
The main thing I had to do that I did not have to do in eclipse was go to Preferences > Compiler > Annotation Processors and set my Processor Path to something like...
[PATH TO AA JARS]/androidannotations-2.7.jar:[PATH TO AA JARS]/androidannotations-api-2.7.jar:[PATH TO AA JARS]/codemodel-2.4.1.jar
