The android_id *should* not change, but can currently be modified.

It's stored in the database located at;
/data/data/com.android.providers.settings/databases/settings.db

Run the query; select * from system;
You'll see plenty of information which can then be changed;
update system set value='dead00beef' where name='android_id';

However, this only changes the android_id when you do a call to
Settings.System.ANDROID_ID - not how google does it through the
GoogleLoginServiceBlockingHelper.
