Handset sales are driven not by hardware features (" what the handset can do ") but the user interface and applications available (" what you can do with the handset ").

手持设备的销售量并不是由硬件特征所驱动的(“手持设备可以做什么”)，而是由用户界面和可选应用来决定的(“你可以用手持设备做什么”)。

Handset manufacturers using Android don't all end up with the same user-facing interface.

用Android系统的手机厂商无法最终给用户提供一个统一的界面。

For example, on a handset device it might be appropriate to display just one fragment at a time for a single-pane user interface.

例如，一个手持设备上也可能是适当的时间为一个单窗格的用户界面，来显示只有一个片段。
