| <p>Android 4.0 引入了新功能，可帮助用户了解和控制他们的设备如何使用网络数据。这项新功能可监测数据的整体使用情况，并支持将会触发通知或停用移动数据（当数据用量超出特定配额时）的警告或限制阈值。</p> |
| <p>该功能还会跟踪每个应用的数据使用情况，这样一来，用户就可以在“设置”应用中直观地了解过往的数据使用情况。用户还可以限制特定应用在后台运行时的数据使用方式。</p> |
| <p>本部分中的文档面向系统集成商和移动运营商，目的是向他们说明将 Android 移植到特定设备时应注意的技术细节。这些细节在下文中有总结，若要进一步讨论，请前往 <a href="mailto:[email protected]">android-porting</a> 论坛。</p> |
