一现象

首次安装时出现以下现象：Android SDK is Unavailable

二原因分析(ping指令)

2.1 使用ping指令查看网络状况

1	ping dl.google.com

2.2 ping结果

zxc@zxc MacBook-Pro ~ % ping dl.google.com
PING dl.google.com (142.250.204.46): 56 data bytes
Request timeout for icmp_seq 0
Request timeout for icmp_seq 1
Request timeout for icmp_seq 2
Request timeout for icmp_seq 3
Request timeout for icmp_seq 4
Request timeout for icmp_seq 5
Request timeout for icmp_seq 6

说明：超时，无法访问 dl.google.com

2.3 通过站长工具，查看可用探测点

1	https://ping.chinaz.com/dl.google.com

如图所示，从中找出一个节点58.254.137.161,同时ping 58.254.137.161，验证是否ping通

2.4 将该点添加到host

1	220.181.174.97 dl.google.com

2.5 ping下dl.google.com

zxc@zxc MacBook-Pro ~ % ping dl.google.com
PING dl.google.com (220.181.174.97): 56 data bytes
64 bytes from 220.181.174.97: icmp_seq=0 ttl=116 time=11.651 ms
64 bytes from 220.181.174.97: icmp_seq=1 ttl=116 time=9.796 ms
64 bytes from 220.181.174.97: icmp_seq=2 ttl=116 time=11.865 ms
64 bytes from 220.181.174.97: icmp_seq=3 ttl=116 time=9.945 ms
64 bytes from 220.181.174.97: icmp_seq=4 ttl=116 time=10.991 ms
64 bytes from 220.181.174.97: icmp_seq=5 ttl=116 time=9.755 ms
64 bytes from 220.181.174.97: icmp_seq=6 ttl=116 time=11.677 ms

三解决

退出重新进入后，发现SDK可用
