title: Using cache in ExoPlayer
body: <p>I'm looking for any example of implementing cache in ExoPlayer. </p>
  
  <p>ExoPlayer has in its library different classes concerning cache and Google explain in this <a href="https://www.youtube.com/watch?v=6VjF638VObA">video</a> that we can implement it with the CacheDataSource class, but Google doesn't provide any demo on it. Unfortunately this seems pretty complicated to use, so I'm currently looking for examples (no success on Google).</p>
  
  <p>Does anyone succeed or has any info that would help ? Thanks.</p>
