 ### Configuring the network stack ###
 
 
-ExoPlayer supports Android's default network stack, as well as Cronet and
-OkHttp. In each case it's possible to customize the network stack for your use
-case. The following example shows how to customize the player to use Android's
-default network stack with cross-protocol redirects enabled:
-
-~~~
-// Build a DefaultHttpDataSource.Factory with cross-protocol redirects enabled.
-DataSource.Factory httpDataSourceFactory =
-    new DefaultHttpDataSource.Factory().setAllowCrossProtocolRedirects(true);
-
-// Wrap the DefaultHttpDataSource.Factory in a DefaultDataSource.Factory, which
-// adds in support for requesting data from other sources (e.g., files,
-// resources, etc).
-DefaultDataSource.Factory dataSourceFactory =
-    new DefaultDataSource.Factory(context, httpDataSourceFactory);
-
-// Inject the DefaultDataSource.Factory when creating the player.
-ExoPlayer player =
-    new ExoPlayer.Builder(context)
-        .setMediaSourceFactory(new DefaultMediaSourceFactory(dataSourceFactory))
-        .build();
-~~~
-{: .language-java}
-
-The same approach can be used to configure and inject HTTP-based
-`DataSource.Factory` implementations provided by the [Cronet extension] and the
-[OkHttp extension], depending on your preferred choice of network stack.
