android - 在 Ubuntu PC 上下载 android SDK

Question

我确实根据放置在 SDK 中的 SDK Readme.txt 运行了以下命令:

$tools/android update sdk --no-ui 

但我收到以下错误:

刷新来源:

Fetching https://dl.google.com/android/repository/addons_list-2.xml

如果我尝试使用 Android-Studio->SDK Manager 执行相同操作，我会在消息框中收到相同的错误。

这是因为没有代理设置吗？

Answer 1

听起来确实像代理或其他网络问题。尝试使用 ping dl.google.com ping 该地址.你应该得到类似的东西:

PING dl.l.google.com (216.58.219.110) 56(84) bytes of data.
64 bytes from mia07s25-in-f14.1e100.net (216.58.219.110): icmp_req=1 ttl=47 time=35.2 ms
64 bytes from mia07s25-in-f14.1e100.net (216.58.219.110): icmp_req=2 ttl=47 time=29.2 ms

直到您使用 Control-C 取消该命令。
