android-sdk_r20.-windows无法正常更新

在www.android.com下载最新版的android-sdk_r20.0.3-windows之后，点击SDK Manager.exe，发现无法显示Updates/New的内容，因此无法进行更新。

菜单Tools-->options中的Force https://...sources to be fetched using http://...勾选上之后，问题依旧。 

最终解决方案：

在C:\WINDOWS\system32\drivers\etc目录下，找到hosts文件，在文件末尾加上

74.125.237.1 dl-ssl.google.com

 

 

 

如下：

view sourceprint?

01	# Copyright (c) 1993-1999 Microsoft Corp.

02

#

03	# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.

04

#

05	# This file contains the mappings of IP addresses to host names. Each

06	# entry should be kept on an individual line. The IP address should

07	# be placed in the first column followed by the corresponding host name.

08	# The IP address and the host name should be separated by at least one

09

# space.

10

#

11	# Additionally, comments (such as these) may be inserted on individual

12	# lines or following the machine name denoted by a '#' symbol.

13

#

14	# For example:

15

#

16	#      102.54.94.97     rhino.acme.com          # source server

17	#       38.25.63.10     x.acme.com              # x client host

18

19	127.0.0.1       localhost

20	74.125.237.1 dl-ssl.google.com

 

问题得到解决。
