android-sdk_r20.0.3-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:WINDOWSsystem32driversetc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:

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。
