<compatible-screens> 在 Android

Question

美好的一天，我正在尝试将屏幕尺寸限制为 google 游戏中的手机（即不是平板电脑）。在我找到这个 article 之后，我将其添加到我的清单文件中：

<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。接下来我还找到了这个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，或者我只能使用小号、普通号、大号和超大号等标签？

在某些时候，我决定通过像这样更新清单来将支持英寸大小增加到 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

所以我的第二个问题 - 我做错了什么或不明白？

老实说，我阅读了所有关于 Whosebug 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

您似乎在尝试将屏幕尺寸限制为仅限手机，而不是平板电脑。很难从你的问题中辨别出来，但无论哪种方式我想我都可以消除困惑。

当您在清单中声明 <compatible-screens> 时，您必须声明每个您希望您的应用兼容的屏幕配置：

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，如果您希望您的应用与更高密度的设备兼容，则必须在 <compatible-screens> 元素中包含这些密度。但更简单的方法是改用 <supports-screens> 元素。根据文档，<supports-screens> 元素不考虑密度：

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"/>

largestWidthLimitDp 属性应该不是必需的，但根据 Material density breakpoints 的设计文档，840dp 似乎是手机的一个很好的限制。

否则，如果您希望更好地控制您的应用与哪些设备兼容，您仍然可以使用 <compatible-screens> 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" />
    <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>

在 Bryan 建议使用构建工具 25.0.1 后，我的解决方案没有再出现构建错误：

<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... 对于新版本，某些设备未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>

旧：

根据 Bryan 的回答，我的清单片段如下所示：

 <!-- 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: String types not allowed (at 'screenDensity' with value '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 "supported devices" 列表中。
