To use this extension you need to clone the ExoPlayer repository and depend on
its modules locally. Instructions for doing this can be found in ExoPlayer's
[top level README][]. In addition, it's necessary to get the Cronet libraries
and enable the extension:

1. Find the latest Cronet release [here][] and navigate to its `Release/cronet`
   directory
1. Download `cronet_api.jar`, `cronet_impl_common_java.jar`,
   `cronet_impl_native_java.jar` and the `libs` directory
1. Copy the three jar files into the `libs` directory of this extension
1. Copy the content of the downloaded `libs` directory into the `jniLibs`
   directory of this extension

* In your `settings.gradle` file, add the following line before the line that
  applies `core_settings.gradle`:

```gradle
gradle.ext.exoplayerIncludeCronetExtension = true;
```
