我正在尝试在 Visual Studio Code 中运行此 Flutter 待办事项列表应用:
https://github.com/LiveLikeCounter/Flutter-Todolist
我遇到了这个错误:
I/flutter (30973): Observatory server failed to start after 11 tries
I/flutter (30973): Could not start Observatory HTTP server:

我运行的是 Windows 10 家庭版。
在对这个问题进行了一些挖掘之后，我尝试过:
- 禁用防病毒软件(在我的例子中为 Windows Defender)
- 禁用防火墙(再次使用 Windows Defender)
- 遵循了这篇文章的建议:Observatory server failed to start - Fails to create Socket Server
这里没有成功。
在我所有的调试、主要和配置文件 AndroidManifest.xml 文件中:
...
<uses-permission android:name="android.permission.INTERNET" />
...
除了我拥有的主要的:
...
<uses-permission android:name="android.permission.INTERNET" android:maxSdkVersion="18" />
...
在我的 pubsec.yaml 文件中，我有:
...
environment:
sdk: ">=2.2.0 <3.0.0"
...
在我的 android/app/build.gradle 文件中，我有:
...
android {
compileSdkVersion 28

此问题发生在 Android 模拟器和我的物理设备上。
我在很多搜索中都看到了这个问题，但我还没有看到明确的解决方案。
任何了解此问题解决方案的人请帮忙。
谢谢。
最佳答案
我缺少\debug\AndroidManifest.xml 内容:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.my_project">
<!-- Flutter needs it to communicate with the running application
to allow setting breakpoints, to provide hot reload, etc.
-->
<uses-permission android:name="android.permission.INTERNET"/>
</manifest>
(将 my_project 替换为您的项目)
文件内容与\profile\AndroidManifest.xml 相同
