Android studio 4.0 编辑器窗口不见了

标签 android code-editor android-studio-4.0

我在 Windows 10 (1909) 版本上使用 Android Studio v 4.0。直到昨晚我的代码编辑器窗口刚刚消失，一切都运行良好。
我试过以下

  • 重新启动并使缓存无效
  • 检查更新
  • 重置默认布局 (shift+F12) [窗口 -> 恢复默认布局]
  • 尝试将文件拖到中心以打开(编辑器永远不会出现，但每个文件的面包屑更新或在下面给出的屏幕截图

    • enter image description here
    许多其他组件也受到影响，例如
  • Logcat 什么都不显示
  • 事件日志没有显示
  • 构建和同步没有显示

    • 另一件奇怪的事情是我无法打开设置 [File -> Settings](它什么也没显示)

    最佳答案

    在浏览日志时发现了这一点。

    ERROR - ij.psi.stubs.StubUpdatingIndex - Error indexing:jar://C:/Users/user/AppData/Local/Android/Sdk/platforms/android-29/android.jar!/android/media/midi/MidiDevice.class

    @Andy你是对的，删除以下文件夹解决了这个问题。
  • C:\Users\user.AndroidStudio4.0\config\plugins
  • C:\Users\user.AndroidStudio4.0\config\cache

    • 虽然在第一次启动工作室抛出异常但在下一次重新启动时一切都很好
