I don't know why, but Android Studio 3.2.1 display a plugin error continuosly. The error is always related to androidAnnotations.jar, like this:
Android Studio/plugins/android/lib/androidAnnotations.jar!/android/content/annotations.xml: Content is not allowed in prolog.
I've updated to latest version of IDE and SDK but the error hasn't been solved. I tried to invalidate caches, reload the project from repository and resync gradle, disable and enable plugins, etc., but without success.
Any suggestion?
