with an `ExoPlayer` is easy:

Passing the `trackSelector` enables additional logging, but is optional and so
`null` can be passed instead.
The easiest way to observe the log is using Android Studio's [logcat tab][]. You
can select your app as debuggable process by the package name (
`com.google.android.exoplayer2.demo` if using the demo app) and tell the logcat
