解決Android SDK下載和更新失敗的方法詳解

最近剛換了電腦，開始搭建Android開發環境的時候，下載SDK總是會出現如下錯誤： 複製代碼 代碼如下:Failed to fetch URL http://dl-ssl.google.com/android/repository/addons_list-1.xml.

說dl-ssl.google.com在大陸被強了，解決方案就是修改C:\Windows\System32\drivers\etc\hosts檔案。添加一行：

複製代碼 代碼如下:74.125.237.1 dl-ssl.google.com

這裡需要注意的是hosts檔案是唯讀，我們沒有許可權修改，需要我們將hosts檔案複製到案頭或者其他地方，然後修改，代碼如下：複製代碼 代碼如下:# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host

# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost
//親，就是增加這一句哦
74.125.237.1 dl-ssl.google.com

然後儲存，複製修改後的hosts檔案到C:\Windows\System32\drivers\etc 目錄，替換檔案就好！！！我們再次下載SDK的時候就會成功啦，如：

嘿嘿，大功告成啦！！！
PS：補充下，在mac或Linux中，hosts檔案所在位置為/etc/hosts，可以使用sudo vim /etc/hosts來編輯。
