<uses-feature> 和 <uses-library> 有什么区别？
What is the difference between <uses-feature> and <uses-library>?
我已经阅读了 android 文档以了解其含义，
但最终还是不清楚两者到底有什么区别。虽然它是一个库，但它也可以被描述为一个特性。如果我们正在创建库或功能，两者有什么用以及何时使用哪一个？
本文来自 App Manifest Overview :
使用功能：
The element allows you to declare hardware and software features your app needs. For example, if your app cannot achieve basic functionality on a device without a compass sensor, you can declare the compass sensor as required with the following manifest tag:
...
<manifest ... >
<uses-feature android:name="android.hardware.sensor.compass"
android:required="true" />
...</manifest>
使用库：
Specifies a shared library that the application must be linked against.
