<p>Android 可帮助用户了解和控制设备使用网络流量的方式。这项新功能可监测流量的整体使用情况,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时)的警告或限制阈值。</p>
<p>该功能还会跟踪每个应用的流量消耗情况,这样一来,用户就可以在<a href="/devices/tech/settings/settings-guidelines">设置</a>应用中直观地了解过往的流量消耗情况。用户还可以限制特定应用在后台运行时的流量使用方式。</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>
