Dianne says that that's what they mean and 10that they therefore should be eliminated. Suchi says that they mean "doesn't require a 11keyboard / navigation control / touch screen to work." But then what does "undefined" mean? 12Seems like some API change is in the works, either eliminating the "no___" values or 13"undefined". Since it's unclear what the change will be, I've chosen to document the "no___" 14and "undefined" attributes using the same language, which is surely wrong but may make it 15easier to update the doc when the change is made... Nov 2013, this still seems unresolved. --> 16 17<dl class="xml"> 18<dt>syntax:</dt> 19<dd><pre class="stx"><uses-configuration 20 android:<a href="#five">reqFiveWayNav</a>=["true" | "false"] 21 android:<a href="#hard">reqHardKeyboard</a>=["true" | "false"] 22 android:<a href="#kbd">reqKeyboardType</a>=["undefined" | "nokeys" | "qwerty" | "twelvekey"] 23 android:<a href="#nav">reqNavigation</a>=["undefined" | "nonav" | "dpad" | "trackball" | "wheel"] 24 android:<a href="#touch">reqTouchScreen</a>=["undefined" | "notouch" | "stylus" | "finger"] /></pre></dd> 25 26<dt>contained in:</dt> 27<dd><code><a href="{@docRoot}guide/topics/manifest/manifest-element.html"><manifest></a></code></dd> 28 29<dt>description:</dt> 30<dd itemprop="description">Indicates what hardware and software features the application requires. 31For example, an application might specify that it requires a physical keyboard 32or a particular navigation device, like a trackball.
