android - Flutter 应用程序无法以 Debug模式启动

Question

我有一个带有调试配置的简单 Flutter 应用程序。在我更改 gradle 配置和其他内容以在 Release模式下构建 apk 之后。我根据文档完成了所有配置，发布构建工作正常。但是现在我无法在 Debug模式下运行应用程序。它显示此错误

I/flutter (15809): Observatory server failed to start after 11 tries
I/flutter (15809): Could not start Observatory HTTP server:

它显示白屏且未加载任何内容。

Answer 1

在构建发布版本时，它说如果应用程序不需要互联网权限，则删除它。但是当我们进行开发时，我们必须保留它。因为需要互联网许可才能进行热重载。添加后

 <uses-permission android:name="android.permission.INTERNET"/>

对于 list ，一切正常
