Problem using the Google Play OBB Downloader

In order to avoid the 50Mb restriction for apps in Google Play I have imported the Google Play OBB Downloader fron the Asset Store in my project, so I can upload and use OBB files.

Also I have followed the tutorial from this page:

When the DownloadObbExample.cs is executed I get this error:

Exception: JNI: Init’d AndroidJavaClass with null ptr!
UnityEngine.AndroidJavaClass…ctor (IntPtr jclass) (at C:/BuildAgent/work/ea95e74f6e5f192d/Runtime/Export/AndroidJavaImpl.cs:533)

There isn’t anything about this in Unity docs.

Any idea?

You get that in Editor or in device?

In the Editor. I know the script is intended to work on Android but at least I woud have to receive the console debug warning telling preciselly that and not the error I receive.
In the Android device the script is not working and no message is showed.

same Problem here…
also devices crashes when try to download obb…
it’s a problem with Unity…
if i use the old Unity Version where i build my original Version with it still works fine…
Latest unity Obb Downloader doesn’t work…
plz help…

many thxx
