在更新之前一切正常。我试图Invalidate / Restart但没有成功。有谁知道这个错误的原因以及如何解决它？

答案 0 :(得分：7)

在从一个Git分支转换到另一个分支后，Android Studio 3.0 Canary 4上的mw也发生了同样的事情 - 当时没有更新工作室或插件。

最后是

的组合
    来自控制台的
  • gradlew clean assembleDebug和
    • Android Studio中的
  • File -> Invalidate Caches / Restart

执行约。 3次帮助了我，但仍然不知道问题出在哪里。

答案 1 :(得分：5)

一个已知问题：As Documented here

就这样做

  • 构建＆gt;从菜单栏中清除项目。
  • 然后通过单击“同步项目”，使用Gradle 同步项目文件 工具栏。

答案 2 :(得分：2)

在Android Studio 3.0 beta 1上发生了同样的事情。升级后，我重建了项目，现在错误不再发生了。
