ibaker ebcdd983e2 Fix demo app UnsafeOptInUsageError lint errors
This change:
* Adds missing `@OptIn` annotation to demo app's `ErrorMessageProvider`
* Switches from `Util.SDK_INT` to `Build.VERSION.SDK_INT` in
  `SampleChooserActivity` (`PlayerActivity` is already using this).

This code hasn't changed recently, and it doesn't fail on the `release`
branch, but it failed when I checked the `main` branch just now - so I
assume lint has updated to detect more cases where unstable APIs are
being used without opt-in. I suspect the difference is due to different
Android Gradle Plugin versions between the branches.

Demos

This directory contains apps that demonstrate how to use Android media modules, like ExoPlayer. Browse the individual demos and their READMEs to learn more.

Running a demo

From Android Studio

  • File -> New -> Import Project -> Specify the root media folder.
  • Choose the demo from the run configuration dropdown list.
  • Click Run.

Using gradle from the command line:

  • Open a Terminal window at the root media folder.
  • Run ./gradlew projects to show all projects. Demo projects start with demo.
  • Run ./gradlew :<demo name>:tasks to view the list of available tasks for the demo project. Choose an install option from the Install tasks section.
  • Run ./gradlew :<demo name>:<install task>.

For example, ./gradlew :demo:installNoDecoderExtensionsDebug installs the ExoPlayer demo app in debug mode with no optional modules.
