ADT在線安裝（http://dl-ssl.google.com/android/eclipse 打不開）
很明顯，國內網絡和諧掉了google這個服務器，能夠強制指向下Hosts ，如下是添加內容：
74.125.237.1 dl-ssl.google.com
具體操做方式：
目錄：c:\windows\system32\drivers\etc下 找到hosts文件，實際上是一個純文本的文件，
一、用記事本打開
二、將：74.125.237.1 dl-ssl.google.com 添加至hosts文件最後一行
三、保存關閉Hosts，從新啓動eclipse
4. 啓動Eclipse，菜單點擊進入Help -> Install New Software，在出現的窗口中點擊Add按鈕，而後在Name中輸入你自定義的名稱,Location中輸入：
http://dl-ssl.google.com/android/eclipse

#這行是爲了方便打開Android開發官網 如今好像不翻q也能夠打開
74.125.113.121 developer.android.com
#更新的內容從如下地址下載
203.208.46.146 dl.google.com
203.208.46.146 dl-ssl.google.com
添加以上的網址，再選用http協議，就能夠正常的進行更新了。
或者也能夠什麼都不作，過上一兩天可能會恢復正常。
