android sdk setup时呈现:Failed to fetch URL https://dl-ssl.google.com/android/repository/repository.xml

在官方下的android SDK的安装包，运行时，呈现:
Failed to fetch URL
https://dl-ssl.google.com/android/repository/repository.xml，
reason: HTTPS SSL error. You might want to force download through HTTP in the
settings.

解决办法:
在安装的页面中，批改****代理设备：
1.Settings里Http Proxy
Server:10.159.192.62，Http Proxy Port:8080
2.选择如下两个选项卡：Force https//.....using
http...，还有一个：Ask Before restaring ADB.
