安卓系统:安装v7 appcompat(appcompat库)时出错

Question

我无法安装app-compat v7库。我正在按照https://developer.android.com/tools/support-library/setup.html

奇怪的是，上面链接中的说明曾经在我的旧系统上起作用。我打开SDK管理器，选择Android支持库，接受许可并安装。但我得到了以下错误。

任何建议都很感激(我花了几个小时试图弄清楚)

Downloading Android Support Library, revision 20
Download interrupted: Connection to http://127.0.0.1:5050 refused
Done. Nothing was installed.

我重新启动了系统。关闭了windows防火墙(我没有防病毒软件)。已启动SDKManager并尝试安装。同样的问题。查看SDKManager日志，我看到以下错误消息(当SDK Manager启动时出现)。我在网上手动打开所有这些错误链接，我确实看到了这些文件。但是，SDK Manager在首次启动时不会获取它们，因此无法安装应用程序compat。关于为什么SDKManager能够提取一些文件而不能提取其他的任何想法

Answer 1

在Android SDK Manager设置菜单Tool->Options->Proxy Settings中，确保HTTP Proxy Server和HTTP Proxy Port为空。

然后在SDK Manager设置菜单中，Packages->Reload。它将再次为您刷新和更新数据。
