 ## Why AndroidVideoCache?
 Because there is no sense to download video a lot of times while streaming!
 `AndroidVideoCache` allows to add caching support to your `VideoView/MediaPlayer`, [ExoPlayer](https://github.com/danikula/ExoPlayer/commit/6110be8559f003f98020ada8c5e09691b67aaff4) or any another player with help of single line!
