title: jsr305_annotations Folder inside apk file
body: <p>I've had reports of problems with the installation of the apk.
  I tried to extract the apk as a zip file and I found the folder
  jsr305_annotations in the root APK
  with inside
  folder: v0_r47 -> file: V0_r47.gwt.xml
  File: Jsr305_annotations.gwt.xml</p>
