How to load an assetbundle for Android after build?

I want to upload my assetbundles to an external server after a build is done, and to do that I need to get an assetbundle that UnityCloud created for me, but I get a WWW error when trying to load the file. The method is being called as a Post-Export method in UnityCloud

I've confirmed that the files are actually being created

The URI that I specify is
file:///BUILD_PATH/xxxxxxxxxxxxxxxxxx.game_project_name.android-development-branch/unity/Assets/StreamingAssets/Android/Android

Code (csharp):

1.  
2.         var abPath = <the URI specified above>
3.         var abDownload = WWW.LoadFromCacheOrDownload( abPath, 0 );
4.         while( !abDownload.isDone )
5.             ;
6.         if(abDownload.error != string.Empty ) {
7.             Debug.LogWarning( abDownload.error );
8.         }

The WWW error I receive is Unknown Error

Is the path I am working with wrong, is there a different way to load the file? I am using Unity 2017.1.1f1

 

I hate bumping, but I still haven't been able to solve this problem. Is there anyone out there that can help?

 

I ended up using File.ReadAllBytes to read in the contents of the file instead of WWW
