    -  locale_whitelist
       List of strings. List of locales to keep from the resources. Can be
       obtained by generating an android build and looking at the content of
       `out/Debug/gen/chrome/java/res`; or looking at the android section in
       `//chrome/app/generated_resources.grd`
       Example: ["am", "ar", "bg", "ca", "cs"]
 
+   - resource_whitelist
+     List of strings. List of resource files to explicitely keep in the final
+     output. Use it to keep drawables for example, as we currently remove them
+     all.
