Streaming Assets Path working on Windows but not on Android.

I've been working with unityGB as a way to implement my own .gb to make an Android app. I've also had many other problems with switching the key inputs to buttons, but that's already fixed. Is there a way I can get the .gb file displayed on screen for Android? (With Unity Remotes works perfectly, but not the apk by itself.) Also, I think the problem is in the first 10 lines or so.

 private IEnumerator LoadRom(string filename)
     {
         string path = ("jar:file://" + Application.streamingAssetsPath + "!/assets" + filename);
         Debug.Log("Loading ROM from " + path + ".");
 
         if (!File.Exists(path))
         {
             Debug.LogError("File couldn't be found.");
             yield break;
         }
 
         WWW www = new WWW("jar:file://" + path);
         yield return www;
 
         if (string.IsNullOrEmpty(www.error))
         {
             Emulator.LoadRom(www.bytes);
             StartCoroutine(Run());
         }
         else
             Debug.LogError("Error during loading the ROM.\n" + www.error);
     }
