构建 AOSP 并为其做出贡献。如需了解详情,请参阅 AOSP 的变更。
Android 流量消耗
使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
Android 可帮助用户了解和控制设备使用网络流量的方式。该功能可监测流量的整体消耗情况,在数据用量超出特定配额时发出警告,或在达到所设上限阈值时触发通知或停用移动数据网络。
此外,还会跟踪每个应用的流量消耗,这样一来,用户就可以在设置应用中直观地了解过往的流量消耗。用户还可以限制特定应用在后台运行时的流量使用方式。
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 android-porting 论坛。
