19<p>Android 4.0 (Ice Cream Sandwich) introduces new features that help
20users understand and control how their device uses network data.  It
21monitors overall data usage, and supports warning or limit thresholds
22which will trigger notifications or disable mobile data when usage
23exceeds a specific quota.</p>
24<p>Data usage is also tracked on a per-application basis, enabling users
25to visually explore historical usage in the Settings app. Users can
26also restrict how specific applications are allowed to use data when
27running in the background.</p>
28<p>The documentation in this section is intended for systems integrators
29and mobile operators, to help explain technical details they should be
30aware of when porting Android to specific devices.  These details are
31summarized below, and the
32<a href="mailto:android-porting+subscribe@googlegroups.com">android-porting</a>
33mailing list is a good place for further discussion.</p>
