当我尝试运行新的示例应用程序时，无法打开 xmltree 错误

Posted 2023-02-23

【中文标题】当我尝试运行新的示例应用程序时，无法打开 xmltree 错误

【英文标题】：Unable to open xmltree error in flutter when i try to run fresh sample app

【发布时间】：2019-11-05 00:06:37

【问题描述】：

每当我尝试从 vscode 运行颤振应用程序时，我都会收到错误

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).

从 android studio 运行相同的应用程序。 同样在安装后，当我运行命令 flutter doctor 时，我也会遇到问题。 在 sdk 中找不到 aapt 文件时出错，所以我将 aapt2 文件复制到同一文件夹中并用 aapt 重命名。

下面分享一下我运行命令flutter run

时创建的日志文件

Flutter crash report; please file at https://github.com/flutter/flutter/issues.

command

flutter run

我正在使用真机进行测试。

【问题讨论】：

这是新创建的flutter应用还是现有的flutter应用？即使使用新项目也会出现此错误吗？

是的，它是新创建的应用程序。

是vscode新创建的吗？我也在做同样的事情，我可以成功部署到我的设备上。请先尝试此处列出的步骤flutter.dev/docs/development/tools/vs-code 这将引导您进入新创建的应用程序和基本环境。我还建议您在这里提交问题github.com/flutter/flutter/issues

感谢 @BarryWang 的支持。我通过将我的 Android SDK 从 28 更新到 29 解决了这个问题..

很高兴知道这一点

【参考方案1】：

感谢@BarryWang 的帮助。 我通过将我的 Android SDK 版本从 28 API 升级到 29 解决了这个问题。

【参考方案2】：

我已经尝试了我的灵魂，它对我有用。

您的问题在 C:\Users\admin\AppData\Local\Android\Sdk\build-tools\28.0.3\ 文件中的 aapt.exe 中

尝试手动执行它大多数时候会出现错误，因为缺少 DLL 文件

你要做的就是将你的版本（sdk 28.0.3）的aapt.exe替换成其他版本的另一个appt.exe 你可以在这个文件夹“C:\Users\admin\AppData\Local\Android\Sdk\build-tools\”中找到安装在你的android studio中的sdks版本 如果您没有其他版本，请安装主题之一（ 在我的情况下，我的应用程序由 sdk 29.0.1 运行，它会产生问题，所以我从 28.0.3 获取 aapt.exe，然后在 sdk 29.0.1 中通过它

祝你好运
