Playing mp4 video - for android from local raw/assets folder

Hello, I am trying to play an mp4 file using exoplayer. I have the mp4 file on my android “raw” folder and it can be moved to “assets” folder if needed.

I have tried modifying the demo app - “SampleChooserAcitivity” as below:

    sampleAdapter.add((Object) new Sample("My Video", path,
            DemoUtil.TYPE_MP4));

I have tried the variable “path” with the below options and none of them work for me.

Option 1 (from assets folder) path = “file:///video.mp4”;

Option 2 (from assets folder) path = “file:///android_asset/video.mp4”;

Option 3 (from raw folder) path = “android.resource://” + getPackageName() + “/” + R.raw.video;

Please suggest. Thanks!
