每当我尝试从vscode运行flutter应用程序时，都会收到错误消息
p同一应用从android studio运行。 同样在安装后，当我运行命令 flutter doctor 时，我也遇到了问题。 错误在SDK中找不到a帆aapt文件，因此我将aapt2文件复制到同一文件夹中，并使用aapt重命名。
下面，我分享了运行命令 flutter run
时创建的日志文件W/ziparchive( 6116): Unable to open 'xmltree': No such file or directory
xmltree: error:failed to open file: The system cannot find the file specified. (2).
颤抖的医生：

谢谢@BarryWang的帮助。 我通过将Android SDk版本从28 API升级到29解决了这个问题。
答案 1 :(得分：0)
我已经尽力了，对我有用。
您遇到的问题是C：\ Users \ admin \ AppData \ Local \ Android \ Sdk \ build-tools \ 28.0.3 \文件中的aapt.exe
尝试手动执行该命令，大多数情况下会出现DLL文件丢失的错误
祝你好运
