推荐答案

删除＆lt;成分名称=FacetManager＆GT; ...＆LT; /成分＆gt; 从 IML 文件

真正的问题是Android的工作室是previous版本配置错误（如 MyProject.iml ）的IDEA文件 - 它增加了一个额外的＆lt;成分名称=FacetManager＆GT; 这不应该是present XML元素。在上述情况下，解决的办法是修改 MyProject.iml 和删除＆lt;成分名称=FacetManager＆GT; 部分，如下所示：

The real problem is that previous version of Android Studio misconfigured the IDEA file (e.g. MyProject.iml) -- it added an extra <component name="FacetManager"> XML element that shouldn't be present. In the case above, the solution is to edit MyProject.iml and to remove the <component name="FacetManager"> part as shown here:

<?xml version="1.0" encoding="UTF-8"?>
<module external.system.id="GRADLE" type="JAVA_MODULE" version="4">
  <component name="FacetManager">
    ...remove this element and everything inside such as <facet> elements...
  </component>
  <component name="NewModuleRootManager" inherit-compiler-output="true">
    ...keep this part...
  </component>
</module>

另外，您可以删除该项目的 .idea 文件夹和 IML 文件并重新导入你的源代码到一个新的Android的Studio项目。

Alternatively you could remove the project's .idea folder and iml files and re-import your sources into a new Android Studio project.
