<Manifest>

Description ):

This attribute is used to specify the applicationProgramRequired hardware and software features. For example, an application can use this element to specify the required physical keyboard or special navigation devices, such as trackballs. Using this specification can avoid installing applications on devices that do not support their work.

If the application can work with different device configurations, it should include an independent <uses-configuration> Declaration for each configuration. Each statement must be completed. For example, an application requires a 5-way navigation control, a touch screen that supports finger operations, a standard QWERTY keyboard, or a 12-key numeric keyboard, therefore, two <uses-configuration> elements are used to specify these requirements:

<Uses-configurationandroid: reqfivewaynav = "true" Android: reqtouchscreen = "finger"
Android: reqkeyboardtype = "qwerty"/>
<Uses-configurationandroid: reqfivewaynav = "true" Android: reqtouchscreen = "finger"
Android: reqkeyboardtype = "twelvekey"/>

Attributes (attributes ):

Android: reqfivewaynav

This attribute is used to specify whether the application requires five-way navigation control. If it is set to true, it is required; otherwise, it is not required. Five-direction control refers to the ability to move the selected object up, down, left, right, and provides a method to call the selected object. It can be a D-pad (direction board), trackball, etc.

If the application requires a direction control, but not a special type of control, you can set this attribute to true and ignore the reqnavigation attribute. However, if an application requires a special type of direction control, you can ignore this attribute and replace it with the reqnavigation attribute settings.

Android: reqhardkeyboard

This attribute is used to specify whether the application requires a hard keyboard. If it is set to true, it is required; otherwise, it is not required.

Android: reqkeyboardtype

This attribute is used to specify any keyboard type required by the application. This attribute does not distinguish between soft and hard keyboards. If a type of hard keyboard is required, use this attribute to specify the type and set the reqhardkeyboard attribute to true.
