30 * A complete Mail activity instance. This is the toplevel class that creates the views and handles
31 * the activity lifecycle.</p>
32 *
33 * <p>This class is abstract to allow many other activities to be quickly created by subclassing
34 * this activity and overriding a small subset of the life cycle methods: for example
35 * ComposeActivity and CreateShortcutActivity.</p>
36 *
37 * <p>In the Gmail codebase, this was called GmailBaseActivity</p>
