All other AndroidX libraries have already increased their min SDK to 21. This change renames private symbols to remove `V21` suffixes and similar, but doesn't change public or protected symbols with similar names, to avoid needless breakages/churn on users of the library. Some of the dead code removal is more complex, so I've split it out into follow-up changes to make it easier to review. PiperOrigin-RevId: 651776556

This is the main ExoPlayer demo app. It uses ExoPlayer to play a number of test streams. It can be used as a starting point or reference project when developing other applications that make use of the ExoPlayer library.
See the demos README for instructions on how to build and run this demo.
