最近使用Android SDK Manager 更新Android SDK tools 发现经常更新失败，获取不到更新信息：

Java代码??

1. Fetching?https://dl-ssl.google.com/android/repository/addons_list-2.xml??
2. Fetched?Add-ons?List?successfully??
3. Fetching?URL:?https://dl-ssl.google.com/android/repository/repository-7.xml??
4. Done?loading?packages.??
5. Fetching?https://dl-ssl.google.com/android/repository/addons_list-2.xml??
6. Failed?to?fetch?URL?https://dl-ssl.google.com/android/repository/addons_list-2.xml,?reason:?peer?not?authenticated??
7. Fetched?Add-ons?List?successfully??
8. Fetching?URL:?https://dl-ssl.google.com/android/repository/repository-7.xml??

?上述是Android SDK Manager Log的更新失败的信息，如下图：

?

这个信息是网络上https的网络连接不上造成的，所以需要把https都换成http。

操作如下，点击SDK Manager的Tools->Options

选择 Force https://... sources to be fetched using http://

如下图，见红色框处

当然如果你有VPN或公司有代理可以连上美国的google，那可以在Proxy里面设置代理的IP和端口

?

?设置完后更新就会成功

?万年连不上Google的服务器的节奏，大致表现是进度条不动，卡在Fetching https://dl-ssl.google.com/android/repository/addons_list-2.xml。?

vi /etc/hosts

74.125.237.1 dl-ssl.google.com

Log的结果如下：
