<compatible-screens>
<!-- all small size screens -->
<screen android:screenSize="small" android:screenDensity="ldpi" />
<screen android:screenSize="small" android:screenDensity="mdpi" />
<screen android:screenSize="small" android:screenDensity="hdpi" />
<screen android:screenSize="small" android:screenDensity="xhdpi" />
<!-- all normal size screens -->
<screen android:screenSize="normal" android:screenDensity="ldpi" />
<screen android:screenSize="normal" android:screenDensity="mdpi" />
<screen android:screenSize="normal" android:screenDensity="hdpi" />
<screen android:screenSize="normal" android:screenDensity="xhdpi" />
</compatible-screens>
但现在看来,使用5.5英寸手机的用户无法安装我的应用程序.接下来我也发现了这个article和图片：
我的第一个问题 – 是否可以将屏幕尺寸限制为特定的英寸值,或者我只能使用小型,普通型,大型和Xlarge等标签？
<compatible-screens>
<!-- all small size screens -->
<screen android:screenSize="small" android:screenDensity="ldpi" />
<screen android:screenSize="small" android:screenDensity="mdpi" />
<screen android:screenSize="small" android:screenDensity="hdpi" />
<screen android:screenSize="small" android:screenDensity="xhdpi" />
<!-- all normal size screens -->
<screen android:screenSize="normal" android:screenDensity="ldpi" />
<screen android:screenSize="normal" android:screenDensity="mdpi" />
<screen android:screenSize="normal" android:screenDensity="hdpi" />
<screen android:screenSize="normal" android:screenDensity="xhdpi" />
<!-- all large size screens -->
<screen android:screenSize="large" android:screenDensity="ldpi" />
<screen android:screenSize="large" android:screenDensity="mdpi" />
<screen android:screenSize="large" android:screenDensity="hdpi" />
<screen android:screenSize="large" android:screenDensity="xhdpi" />
</compatible-screens>
但使用5.5英寸手机甚至5.2英寸的用户仍然无法安装应用程序.
所以我的第二个问题 – 我做错了什么或不明白？
我老老实实地读了关于stackoverflow和android文档中的文章的所有类似问题,并没有找到正确的答案.谢谢.
解决方法
声明< compatible-screens>时在您的清单中,您必须声明您希望应用与之兼容的每个屏幕配置：
You must declare each one of these; any combination of size and
density that you do not specify is considered a screen configuration
with which your application is not compatible.
我怀疑你提到的5.5英寸手机的密度比xhdpi高;例如xxhdpi或xxxhdpi.文档中省略了这些密度(因为文档已过时或不完整)但仍然相关;它们记录在<compatible-screens>页面上.
因此,如果您希望自己的应用与更高密度的设备兼容,则必须在< compatible-screens>中包含这些密度.元件.但更简单的方法是使用< supports-screens>元素而不是.根据文档,< supports-screens> element不考虑密度：
Note: Although you can also use the
<compatible-screens>element for the reverse scenario (when your application is not compatible with
smaller screens),it’s easier if you instead use the
<supports-screens>as discussed in the next section,because it
doesn’t require you to specify each screen density your application
supports.
有了这个,您只需在清单中指定以下内容：
<supports-screens android:smallScreens="true"
android:normalScreens="true"
android:largeScreens="false"
android:xlargeScreens="false"
android:largestWidthLimitDp="840"/>
不应该使用largestWidthLimitDp属性,但基于density breakpoints的Material Design文档,840dp似乎是手机的一个很好的限制.
否则,您仍然可以使用< compatible-screens>如果您希望对应用兼容的设备进行更精细的控制,请使用以下标记：
<compatible-screens>
<!-- all small size screens -->
<screen android:screenSize="small" android:screenDensity="ldpi" />
<screen android:screenSize="small" android:screenDensity="mdpi" />
<screen android:screenSize="small" android:screenDensity="hdpi" />
<screen android:screenSize="small" android:screenDensity="xhdpi" />
<screen android:screenSize="small" android:screenDensity="xxhdpi" />
<screen android:screenSize="small" android:screenDensity="xxxhdpi" />
<!-- all normal size screens -->
<screen android:screenSize="normal" android:screenDensity="ldpi" />
<screen android:screenSize="normal" android:screenDensity="mdpi" />
<screen android:screenSize="normal" android:screenDensity="hdpi" />
<screen android:screenSize="normal" android:screenDensity="xhdpi" />
<screen android:screenSize="normal" android:screenDensity="xxhdpi" />
<screen android:screenSize="normal" android:screenDensity="xxxhdpi" />
</compatible-screens>
