Question

最近，当我尝试构建任何项目时，都会发生此错误，

Android resource compilation failed
E:\Android Projects\BarcodReader\app\src\main\res\drawable\ic_launcher_background.xml:12: error: not well-formed (invalid token).
E:\Android Projects\BarcodReader\app\src\main\res\drawable\ic_launcher_background.xml: error: file failed to compile.

这是文件ic_launcher_background.xml

<component name="libraryTable">
    <library name="Gradle: junit:junit:4.12@jar">
        <CLASSES>
            <root url="jar://$USER_HOME$/.gradle/caches/modules-2/files-2.1/junit/junit/4.12/2973d150c0dc1fefe998f834810d68f278ea58ec/junit-4.12.jar!/" />
        </CLASSES>
        <JAVADOC />
        <SOURCES>
            <root url="jar://$USER_HOME$/.gradle/caches/modules-2/files-2.1/junit/junit/4.12/a6c32b40bf3d76eca54e3c601e5d1470c86fcdfa/junit-4.12-sources.jar!/" />
        </SOURCES>
    </library>
</component>

当我将鼠标悬停在文件上时，它将显示此错误

属性缺少Android名称空间前缀，检查信息：大多数Android视图在Android名称空间中都有属性。引用这些属性时，必须包含名称空间前缀，否则aapt会将您的属性解释为只是一个自定义属性。同样，在清单文件中，几乎所有属性都应位于android：命名空间中。问题ID：MissingPrefix

什么可能导致此错误？

Answer 1

ic_launcher_background.xml是一个IDEA文件，而不是Android资源文件。

只需将其替换为任何有效的Android资源XML文件，即可构建。
