android - Android 中的

Question

美好的一天，我正在尝试将屏幕尺寸限制为仅适用于 Google Play 中的手机(即不是平板电脑)。在我找到这个 article 之后我将此添加到我的 list 文件中:

<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>

但是现在5.5++英寸手机的用户似乎无法安装我的应用程序。接下来我也找到了这个article和里面的图片:

我的第一个问题 - 是否可以通过特定的英寸值来限制屏幕尺寸，或者我只能使用小、普通、大和超大等标签？

在某些时候，我决定通过像这样更新 list 来将支持的英寸大小增加到 7:

<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>

但是5.5寸甚至5.2寸的用户还是无法安装app。

那么我的第二个问题 - 我做错了什么或不明白？

老实说，我阅读了所有关于 stackoverflow 的类似问题和 android 文档中的文章，但没有找到正确的答案。谢谢。

在 Bryan 建议使用构建工具 25.0.1 之后，我的解决方案不再出现构建错误:

<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" />

但是...在新版本中，一些设备没有出现在支持的设备列表中(Google Play 控制台):Google Pixel、Nexus 5x、Google Pixel XL、Nexus 6、Nexus 6P。

这就是为什么我的新解决方案看起来像这样:

<!-- just handsets allowed-->
<compatible-screens>
    <!-- all small size screens -->
    <screen android:screenSize="small" android:screenDensity="ldpi" /> <!-- 120 -->
    <screen android:screenSize="small" android:screenDensity="mdpi" /> <!-- 160 -->
    <screen android:screenSize="small" android:screenDensity="hdpi" /> <!-- 240 -->
    <screen android:screenSize="small" android:screenDensity="280" /> <!-- Workaround -->
    <screen android:screenSize="small" android:screenDensity="xhdpi" /> <!-- 320 -->
    <screen android:screenSize="small" android:screenDensity="360" /> <!-- Workaround -->
    <screen android:screenSize="small" android:screenDensity="420" /> <!-- Workaround Google Pixel, Nexus 5x -->
    <screen android:screenSize="small" android:screenDensity="xxhdpi" /> <!-- 480 -->
    <screen android:screenSize="small" android:screenDensity="560" /> <!-- Workaround Google Pixel XL, Nexus 6, Nexus 6P -->
    <screen android:screenSize="small" android:screenDensity="xxxhdpi" />  <!-- 640 -->
    <!-- all normal size screens -->
    <screen android:screenSize="normal" android:screenDensity="ldpi" /> <!-- 120 -->
    <screen android:screenSize="normal" android:screenDensity="mdpi" /> <!-- 160 -->
    <screen android:screenSize="normal" android:screenDensity="hdpi" /> <!-- 240 -->
    <screen android:screenSize="normal" android:screenDensity="280" /> <!-- Workaround -->
    <screen android:screenSize="normal" android:screenDensity="xhdpi" />  <!-- 320 -->
    <screen android:screenSize="normal" android:screenDensity="360" /> <!-- Workaround -->
    <screen android:screenSize="normal" android:screenDensity="420" /> <!-- Workaround Google Pixel, Nexus 5x -->
    <screen android:screenSize="normal" android:screenDensity="xxhdpi" /> <!-- 480 -->
    <screen android:screenSize="normal" android:screenDensity="560" /> <!-- Workaround Google Pixel XL, Nexus 6, Nexus 6P -->
    <screen android:screenSize="normal" android:screenDensity="xxxhdpi" /> <!-- 640 -->
</compatible-screens>

根据 Bryan 的回答，我的 list fragment 如下所示:

 <!-- just handsets allowed-->
<compatible-screens>
    <!-- all small size screens -->
    <screen android:screenSize="small" android:screenDensity="ldpi" /> <!-- approximately 120 dpi -->
    <screen android:screenSize="small" android:screenDensity="mdpi" /> <!-- approximately 160 dpi -->
    <screen android:screenSize="small" android:screenDensity="hdpi" /> <!-- approximately 240 dpi -->
    <screen android:screenSize="small" android:screenDensity="280" /> <!-- Workaround -->
    <screen android:screenSize="small" android:screenDensity="xhdpi"/> <!-- approximately 320 dpi -->
    <screen android:screenSize="small" android:screenDensity="360" /> <!-- Workaround -->
    <screen android:screenSize="small" android:screenDensity="420" /> <!-- Workaround -->
    <screen android:screenSize="small" android:screenDensity="480" /> <!-- Workaround -->
    <screen android:screenSize="small" android:screenDensity="560" /> <!-- Workaround -->
    <screen android:screenSize="small" android:screenDensity="640" /> <!-- Workaround -->
    <!-- all normal size screens -->
    <screen android:screenSize="normal" android:screenDensity="ldpi" /> <!-- approximately 120 dpi -->
    <screen android:screenSize="normal" android:screenDensity="mdpi" /> <!-- approximately 160 dpi -->
    <screen android:screenSize="normal" android:screenDensity="hdpi" /> <!-- approximately 240 dpi -->
    <screen android:screenSize="normal" android:screenDensity="280" /> <!-- Workaround -->
    <screen android:screenSize="normal" android:screenDensity="xhdpi"/> <!-- approximately 320 dpi -->
    <screen android:screenSize="normal" android:screenDensity="360" /> <!-- Workaround -->
    <screen android:screenSize="normal" android:screenDensity="420" /> <!-- Workaround -->
    <screen android:screenSize="normal" android:screenDensity="480" /> <!-- Workaround -->
    <screen android:screenSize="normal" android:screenDensity="560" /> <!-- Workaround -->
    <screen android:screenSize="normal" android:screenDensity="640" /> <!-- Workaround -->
</compatible-screens>

无法使用 Bryan 的解决方案，因为我遇到编译错误:“AAPT:不允许字符串类型(在‘screenDensity’上值为‘xxxhdpi’)”

它适用于(较新的)设备，例如 Google Pixel (2.6 * 160 dp = 416 dp -> 420dp -> explanation: )/Pixel XL (3.5 * 160 dp = 560 dp) 或三星 Galaxy S6 (4.0 * 160) dp = 640 dp)。dp 值在此处描述:https://material.io/devices/

我认为这可行，因为我上面提到的设备出现在 Google Play 控制台的“支持的设备”列表中。
