问题：

Android设备监视器将不会从Android Studio或Terminal-UnsupportedClassVersionError启动

范京
2023-03-14

当我尝试在Mac上从Android Studio的工具窗口启动Android设备监视器时，我收到以下错误。

当我打开日志文件时，我发现一个错误报告与另一个非常相似，所以问题与此类似，特别是这个。然而，使用sudo对我来说并不起作用，尽管我得到了类似的错误数据，尽管要短得多：

Macs-MBP:tools macuser$ sudo ./monitor

背景故事：在这台笔记本电脑（El Capitan）上完成了一个全新的Android Studio安装后，我尝试从IDE内部启动显示器。它抱怨说运行它需要Java1.6。所以我安装了Java6。然后当我尝试它时，我得到了上面的错误消息。

  • JDK 1.2=46
  • JDK 1.1=45
