* 描述：
Indicates what hardware and software features the application requires. For example, an application might specify that it requires a physical keyboard or a particular navigation device, like a trackball. The specification is used to avoid installing the application on devices where it will not work.
指示该应用程序需要什么硬件和软件特性。例如，一个应用程序可能指定它需要一个物理键盘或一个特殊的导航设备，像一个轨迹球。使用此规范来避免在它不能运行在的设备上安装该应用程序。
If an application can work with different device configurations, it should include separate <uses-configuration> declarations for each one. Each declaration must be complete. For example, if an application requires a five-way navigation control, a touch screen that can be operated with a finger, and either a standard QWERTY keyboard or a numeric 12-key keypad like those found on most phones, it would specify these requirements with two <uses-configuration> elements as follows:
如果一个应用程序可以应付不同设备配置，那么它应该为每个配置包含分离的<uses-configuration>声明。每个声明必须是完整的。例如，如果一个应用程序需要一个五方向的导航控制，一个可以用手指操作的触摸屏，以及一个标准QWERTY键盘（注：就是指平时PC机用的那种键盘）或一个像在大多数电话上找到的那种数字12键的数字键盘，那么它会用两个<uses-configuration>元素指定这些需求，如下：
-------------------------------
<uses-configuration android:reqFiveWayNav="true" android:reqTouchScreen="finger"
android:reqKeyboardType="qwerty" />
<uses-configuration android:reqFiveWayNav="true" android:reqTouchScreen="finger"
android:reqKeyboardType="twelvekey" />
-------------------------------
* attributes:
* 属性：
* android:reqFiveWayNav
Whether or not the application requires a five-way navigation control — "true" if it does, and "false" if not. A five-way control is one that can move the selection up, down, right, or left, and also provides a way of invoking the current selection. It could be a D-pad (directional pad), trackball, or other device.
应用程序是否需要一个五方向导航控制——"true"如果它需要，而"false"如果它不需要。一个五方向控制是指可以把选择向上，向下，向右，或向左移动，并且还提供一种方式调用当前的选择。它可以是一个D-pad（方向板），轨迹球，或其它设备。
If an application requires a directional control, but not a control of a particular type, it can set this attribute to "true" and ignore the reqNavigation attribute. However, if it requires a particular type of directional control, it can ignore this attribute and set reqNavigation instead.
如果一个应用程序需要一个方向控制，但不是一种特定类型的控制，那么它可以设置这个属性为"true"并且忽略reqNavigation属性。然而，如果它需要一种方向控制的特定类型，那么可以忽略此属性并且改为设置reqNavigation属性。
* android:reqHardKeyboard
Whether or not the application requires a hardware keyboard — "true" if it does, and "false" if not.
应用程序是否需要一个硬件键盘——"true"如果它需要，而"false"如果不需要。
* android:reqKeyboardType
The type of keyboard the application requires, if any at all. This attribute does not distinguish between hardware and software keyboards. If a hardware keyboard of a certain type is required, specify the type here and also set the reqHardKeyboard attribute to "true".
应用程序必需的键盘的类型，如果有的话。这个属性没有区分硬键盘和软键盘。如果某类型的硬键盘是必需的，在这里指定该类型，同时还也设置reqHardKeyboard为"true"。
The value must be one of the following strings:
值必须是以下字符串之一：
-------------------------------
* Value Description
* 值 描述
* "undefined" The application does not require a keyboard. (A keyboard requirement is not defined.) This is the default value.
* "undefined" 应用程序不需要键盘。（键盘要求没有被定义。）这是默认值。
* "nokeys" The application does not require a keyboard.
* "nokeys" 应用程序不需要键盘。
* "qwerty" The application requires a standard QWERTY keyboard.
* "qwerty" 应用程序需要一个标准QWERTY键盘。
* "twelvekey" The application requires a twelve-key keypad, like those on most phones — with keys for the digits from 0 through 9 plus star (*) and pound (#) keys.
* "twelvekey" 应用程序需要一个12键键盘，像大多数电话上的那样——带有表示从0到9的数字加上星号（*）和井号（#）键的按键。
-------------------------------
* android:reqNavigation
The navigation device required by the application, if any. The value must be one of the following strings:
应用程序必需的导航设备，如果有的话。值必须是以下字符串之一：
-------------------------------
* Value Description
* 值 描述
* "undefined" The application does not require any type of navigation control. (The navigation requirement is not defined.) This is the default value.
* "undefined" 应用程序不需要任意导航控制类型。（导航要求没有被定义。）这是默认值。
* "nonav" The application does not require a navigation control.
* "nonav" 应用程序不需要一个导航控制。
* "dpad" The application requires a D-pad (directional pad) for navigation.
* "dpad" 应用程序需要一个D-pad（方向板）用于导航。
* "trackball" The application requires a trackball for navigation.
* "trackball" 应用程序需要一个轨迹球用于导航
* "wheel" The application requires a navigation wheel.
* "wheel" 应用程序需要一个导航滚轮。
-------------------------------
If an application requires a navigational control, but the exact type of control doesn't matter, it can set the reqFiveWayNav attribute to "true" rather than set this one.
如果一个应用程序需要一个导航控制，但具体的控制类型不要紧，那么可以设置reqFiveWayNav属性为"true"而非设置这个属性。
* android:reqTouchScreen
The type of touch screen the application requires, if any at all. The value must be one of the following strings:
应用程序需要的触摸屏的类型，如果有的话。该值必须是以下字符串之一：
-------------------------------
* Value Description
* 值 描述
* "undefined" The application doesn't require a touch screen. (The touch screen requirement is undefined.) This is the default value.
* "undefined" 应用程序不需要一个触摸屏。（触摸屏要求是未定义的。）这是默认值。
* "notouch" The application doesn't require a touch screen.
* "notouch" 应用程序不需要一个触摸屏。
* "stylus" The application requires a touch screen that's operated with a stylus.
* "stylus" 应用程序需要一个触摸屏，它用手写笔来操作。
* "finger" The application requires a touch screen that can be operated with a finger.
* "finger" 应用程序需要一个触摸屏，它可以用手指来操作。
