GooglePlay OBB Downloader crashing after splashscreen

Hello,

What is happenning is this:

I am building the apk with one « sceneLoader » scene (with the DownloadObbExample script attached to Main Camera), and when I execute it in the device (Motorola Xoom) the aplications just closes after showing the splash screen (I am only including this “sceneLoader” scene in the build settings). I have tried with the DownloadObbExample that is included in the asset store, and with the one made by Anthony Kozak in this site: http://labs.exoa.fr/tutorial-unity-4-apk-splitting-google-play-obb/ and both crash after splash screen.

I have not even been able to test if my obb file works from Google Play…

I also noticed something else:
When I click « play » on the editor I can see the message « Use GooglePlayDownloader only on Android device! » and doing some tests it seems that the program is crashing a little later after that on these lines:
GooglePlayDownloader.cs
→ populateOBBData()
→ AndroidJavaObject package_info = etc, etc, etc.

The console says:

Thanks for reading, and a lot of more thanks if someone can give me some leading advice.

PD: I am using Unity 3.5.2

Is anybody found any solution regarding this problem???

Did you try to put in your BASE64_PUBLIC_KEY from android market?
