Load video from oculus go file

Hi
I'm trying to dynamic load one 360 video from a specific folder by videoplayer component file, it works on android device but I couldn't make it work on oculus go

Thanks for your time and response
here the code:

        VideoPlayer vp = gameObject.AddComponent<VideoPlayer>();
        url = "file:///mnt/sdcard/Apregon/VR_Kiosk-Movie.mp4";
        vp.url = url;
        vp.renderMode = VideoRenderMode.MaterialOverride;
        vp.targetMaterialRenderer = GetComponent<Renderer>();
        vp.targetMaterialProperty = "_MainTex";
        vp.Play ();
