Need some comments here about how I am looking in the dictionary defined by the
DEPS file to find the hook with the name 'sdkextras', and from that taking the
list of arguments to the download_sdk_extras.py script (e.g.
google_google_play_services_21.0.zip) and from that determining the name of the
package (e.g. google play services).

The name will be used by sdk/tools/android update to install the corresponding
package.

What about maintaining the list of these packages in a separate (json?) file?
and then read that file for this step and pass it as an argument to
download_sdk_extras.py in DEPS?

You could try doing them as more structured data instead of just a zip path...
something like:

{
  'dir_name': 'google',
  'package': 'google_play_services',
  'version': '1.0.0',
  'zip': 'google_google_play_services_1.0.0.zip',
}

but I don't know if that would make these scripts and such any simpler or not.

That's a good suggestion, because I don't like that i have to do a 'python -c'
in the install-build-deps-android.sh just to get the package name. For that
reason, I'm thinking of just using a text file that is easily grep'able in bash
rather than a json file, which I will not know how to read from bash without
again doing a 'python -c' (which would at least be an easier 'python -c' command
than the one in this patch).
