The library cant load from Http, you need download file and load from local Uri.

And remember you need android.permission.WRITE_EXTERNAL_STORAGE for download and read file.

As per android official doc :

Android 6.0 Marshmallow introduced a new permissions model that lets apps request permissions from the user at runtime, rather than prior to installation. Apps that support the new model request permissions when the app actually requires the services or data protected by the services.
