颤振，Gradle 无法在 https 上运行

Question

猜你的日子过得很好！

刚刚将我的系统从 windows 8 格式化到 windows 10，我想快速深入了解 Flutter，所以我开始使用它，然后我下载了 android studio。

我下载了 Git，下载了 Flutter（并将 Flutter sdk 的路径添加到用户路径中），我下载了 Android Studio，然后安装了 Flutter 和 dart 插件。

一切正常，运行flutter --version, flutter doctor，它运行良好。

挑战 一旦我点击 android studio 中的运行或调试按钮，我确实会收到这些错误

几个小时以来，我尝试了不同的方法，但仍然出现上述错误，因此我决定浏览错误中存在的以下域 1) gradle.org 2）flutter.io

看它不工作，我得到了这个页面不工作 {域名}没有发送任何数据。

但是当我将 https:// 添加到上述域名时，它可以在浏览器中正常工作

我现在的问题是

如何将 https:// 添加到 android 中的 gradle 属性或插件

Answer 1

是的，是的，是的！

花了很长时间试图用颤振在 android studio 上运行之后，以下是我所做的事情，老实说，我什至不知道是哪一个让它运行起来。

我从 github 得到了一些答案 https://github.com/flutter/flutter/issues/48494 我下载了 所有 android sdk 版本（全部），我重新启动系统并尝试 瞧，Flutter Program 在我的模拟器上运行了。

Answer 2

此问题主要是由于您的网络或防火墙或您在系统中启用的代理中的一些错误。尝试通过 USB Tethering 连接到 移动互联网并运行 Flutter 应用程序。 这个工作完美，卸载并重新安装 android studio 或 Flutter SDK 并不能解决它。

Answer 3

升级到 Flutter 1.17 后我也遇到了同样的问题

maven {
        url 'http://download.flutter.io'
      }

将此添加到 android->build.gradle->allprojects->repositories 解决了这个问题。

这个问题的主要原因似乎是我的国家已经屏蔽了一些谷歌 API。我完全不知道他们为什么要这样做。

Answer 4

我也面临这个问题几个小时。将 maven 添加到 build.gradle 后，它也显示错误。最后通过执行以下步骤解决 -

- add to build.gradle under repositories in both buildscript and allprojects section

maven {
        url 'http://download.flutter.io'
    }

- and also run on command line 'flutter pub cache repair'

Answer 5

我的情况

flutter pub cache repair

帮助我
