Question

My goal is to understand every single bit of the following example:

http://code.google.com/p/google-api-java-client/wiki/AndroidAccountManager

I can run the example successfully, but now I want to understand every single
line of code in the example. For as far as the standard android APIs I can look
up their function by googling them up and looking at developer.android.com, but
for the other lines that come from the Google APIs I cannot find the up-to-date
1.6 sources on the web for clsses such as the following:

import com.google.api.client.extensions.android2.AndroidHttp;
import com.google.api.client.googleapis.auth.clientlogin.ClientLogin;
import com.google.api.client.http.HttpResponse;
import com.google.api.client.http.HttpResponseException;
import com.google.api.client.http.HttpTransport;
import com.google.api.client.http.InputStreamContent;
import com.google.api.client.util.DateTime;
import com.google.api.services.picasa.PicasaClient;
import com.google.api.services.picasa.PicasaUrl;
import com.google.api.services.picasa.model.AlbumEntry;
import com.google.api.services.picasa.model.UserFeed;

I cannot see any JavaDoc in eclipse, so the only alternative I have to learn about
these is to look at the code. How can I use mercurial to sign out up to date copies
of the Google APIs including those classes that can be used on android?

I think, since I cannot find what I want on the web is to grab the sources
as that seems to be the only way to learn what I need, but I don’t know how
to use hg to do this, because I don’t know how to use hg nor the site where
I can get the sources from.

Thank you for your help,
