My Solution:

  public static DashManifest downloadManifest(HttpDataSource dataSource, String manifestUriString)
      throws IOException
  {
    String local_file_sufix = "file:";
    if (manifestUriString.startsWith(local_file_sufix) )
    {
      String file_to_Open  = manifestUriString.toString().replace(local_file_sufix,"");
      Uri uri = Uri.parse(file_to_Open);
      File file = new File(file_to_Open);
      FileInputStream fileInputStream = new FileInputStream(file);

      DashManifestParser parser = new DashManifestParser();
      return parser.parse(uri, fileInputStream);
    }
    else
    {

      DataSourceInputStream inputStream = new DataSourceInputStream(
              dataSource, new DataSpec(Uri.parse(manifestUriString)));
      try
      {
        inputStream.open();
        DashManifestParser parser = new DashManifestParser();
        return parser.parse(dataSource.getUri(), inputStream);
      }
      finally
      {
        inputStream.close();
      }
    }
  }

@yanivlankry this should be fixed when the latest changes published to GitHub.
If you wish, until then you can load local and online manifests with:

defaultDataSource = new DefaultDataSource(<parameters>);
DashUtil.loadManifest(defaultDataSource, manifestUri)

thank you , i'll try

This is fixed already in dev-v2. OfflineLicenseHelper no longer has a dependency on DashUtil.
