Add custom HTTP headers (Android v3)

If your content server allows for HTTP header authentication, you can apply HTTP headers to your self-hosted, registered content. HTTP headers prevent unauthorized downloads of your content.

To authorize your content request with HTTP headers, use the following steps:

1. Create a Map<String, String> object and name it, for example, httpHeaders.
2. Define httpHeaders.
3. Add httpHeaders to a PlaylistItem.
   
   Java

   // Create a list to contain the PlaylistItems
   List<PlaylistItem> playlist = new ArrayList<>();
   
   // Create key-value map for the HTTP headers
   Map<String, String> httpHeaders = new HashMap<>();
   httpHeaders.put("cookie", "abcd1234");
   		
   // Add a PlaylistItem pointing to the first piece of content
   PlaylistItem content = new PlaylistItem.Builder()
       .file("http://content/http-header-protected-content.m3u8")
       .httpHeaders(httpHeaders)
       .build();
   		
   // Add the content to the playlist
   playlist.add(content);
