ExoPlayer - play local mp4 file in SD card

Question

I am using the Exoplayer Demo app and want to preload a MP4 video from SD card. I have tried out the implementation from this post, but it does not work. There is no such class

Answer 1

For those looking to load from the assets folder:

assets/xyz.mp4

it works by loading the file with:

"file:/android_asset/xyz.mp4"

and using the DefaultDataSourceFactory. Checked on exoplayer 2.4.4.
