enable Annotation Processors option in Android Studio 2.2

Question

I\'m trying to use java 8 in my project and for that I added the jack compiler.

After enabling jack I started having problems with libraries that use Annotation Proc

Answer 1

Open compiler.xml in the .idea folder. I had the following:

<annotationProcessing>
  <profile default="true" name="Default" enabled="false">
    <processorPath useClasspath="true" />
  </profile>
</annotationProcessing>

I simply changed enable to true and re-opened project.

Answer 4

Sometimes the annotate option will be grayed out if the project is not integrated into version control. So goto VCS->Enable version control integration then voila you will see the annotate option and can see the author name beside the line numbers on the editor.
