Android 完整备份 : "file.xml is not in an included path"

Question

我已经像示例中一样创建了备份规则文件 https://developer.android.com/guide/topics/data/autobackup :

<?xml version="1.0" encoding="utf-8"?>
<full-backup-content xmlns:android="http://schemas.android.com/apk/res/android">
    <include
        domain="sharedpref"
        path="." />
    <exclude
        domain="sharedpref"
        path="nonceStorage.xml" />
    <exclude
        domain="sharedpref"
        path="localStorage.xml" />
</full-backup-content>

Android Studio 说有错误:

Error:(8, 15) `nonceStorage.xml` is not in an included path [FullBackupContent]
Error:(11, 15) `localStorage.xml` is not in an included path [FullBackupContent]

错误消息完全没有信息意义，也无法通过谷歌搜索(几乎所有单词都很短)。谁能解释一下，这个***想从我这里得到什么？如何解决这个问题？

Answer 1

我猜这是一个 IDE 错误，因为 the example from doc :

<?xml version="1.0" encoding="utf-8"?>
<full-backup-content>
    <include domain="sharedpref" path="."/>
    <exclude domain="sharedpref" path="device.xml"/>
</full-backup-content>

在 device.xml 上显示相同的错误.

删除 <include>如果您只是想排除一些文件，则清除错误，因为文档说

By default, Auto Backup includes almost all app files.
