Android SDK管理器错误下载中断: Unexpected HTTP Status 503

Question

我无法从 SDK 管理器安装任何东西。我已经尝试在工具-> 选项强制 https://上选中和取消选中复选框，但它会在 logcat 上显示下载中断:意外的 HTTP 状态 503。可能是什么问题？我的互联网连接适用于 http 和 https 协议(protocol)。

Answer 1

503 HTTP 状态码表示服务暂时不可用。根据 W3C's HTTP status code definitions :

The server is currently unable to handle the request due to a temporary overloading or maintenance of the server. The implication is that this is a temporary condition which will be alleviated after some delay. If known, the length of the delay MAY be indicated in a Retry-After header. If no Retry-After is given, the client SHOULD handle the response as it would for a 500 response.

我建议稍等片刻，然后重试。
