Google Play OBB Downloader crash with "android.content.res.Resources$NotFoundException: Resource ID #0x0"

I am trying to use GooglePlayDownloader. When I call GooglePlayDownloader.FetchOBB(); the app crash.

This exception appear to be related with the activity trying to get the interface elements by its ID, but the Jar file is untouched from unity store. It is a very old device (2.3.7), but appear to be ok with minimal version.

I am lost… (or I need to take a brake :P)

Log files. I had only replaced my bundle per XXX.

The problem is strings.xml conflicts between plugins.
