如何指定不允许使用 android:dataExtractionRules 和

Question

我目前的 android 申请目标是 12 岁及以上。

我不想允许任何类型的备份并且当前有这些清单设置

    android:allowBackup="false"
    android:fullBackupContent="false"

但是 android:allowBackup="false" 设置现在给出以下警告

The attribute android:allowBackup is deprecated from Android 12 and higher and may be removed in future versions. Consider adding the attribute android:dataExtractionRules specifying an @xml resource which configures cloud backups and device transfers on Android 12 and higher.

我查看了 android:dataExtractionRules xml 和 none 的示例，其中展示了如何配置 allowBackup="false".

的等效项

我错过了什么？

使用android:dataExtractionRules xml

是否可以达到allowBackup="false"

Answer 1

将 dataExtractionRules 属性添加到您的 AndroidManifest.xml 文件并引用 data_extraction_rules.xml 文件：

<application
    android:allowBackup="false"
    android:fullBackupContent="false"
    android:dataExtractionRules="@xml/data_extraction_rules"
    ...>

然后，排除所有可能用于云备份和d2d传输的域，更新或创建一个文件app/src/main/res/xml/data_extraction_rules。xml:

<data-extraction-rules>
    <cloud-backup>
        <exclude domain="root" />
        <exclude domain="file" />
        <exclude domain="database" />
        <exclude domain="sharedpref" />
        <exclude domain="external" />
    </cloud-backup>
    <device-transfer>
        <exclude domain="root" />
        <exclude domain="file" />
        <exclude domain="database" />
        <exclude domain="sharedpref" />
        <exclude domain="external" />
    </device-transfer>
</data-extraction-rules>

dataExtractionRules 属性 is available 用于 API 31（Android 12）及更高。保留 API 31.

之前的 Android 版本的 allowBackup 和 fullBackupContent 属性

Note to maybe silence "Attribute dataExtractionRules is only used in API level 31 and higher (current min is 19)" warning, with tools:targetApi="s" attribute as well (because older platforms simply ignore manifest-attributes they don't support, and the warning is useless).
