如果我尝试选择一个未下载的包，则会出现相同的窗口。几个月前，我一直在使用 eclipse 和 android 的 sdk，没有任何问题。今天我打开IDE并尝试下载一些东西，但没有成功。有谁知道发生了什么事？

Answer 1

解决方法：打开 SDK Manager 点击顶部菜单中的工具 -> 选项并开启“force h ttps://...sources”

Answer 2

打开 SDK 管理器 --> 包 ---> 重新加载。它将重新加载所有新包。

Answer 3

如果您使用的是代理服务器，那么您也可以设置代理。屏幕截图如下：

Answer 4

我通过安装最新版本的 Java 在我的 Mac 上解决了这个问题——这刷新了证书并清除了算法错误。我通过在从另一台工作机器导入一些证书之前未能导出证书来实现这一点。
