在Eclipse中開發Android 程序，使用ADT版本如下：
Android Developer Tools
Build: v22.0.5-757759
查看libs中jar中的源代碼時，出現下面的提示：
The Jar of this class file belongs to container 'Android Dependencies' which does not allow modifications to source attachments on its entries。
解決的辦法：
在libs目錄下，也就是要查看jar包所在的路徑下，創建一個新文件，文件的名字爲 要查看的jar包名字＋.properties
比如：我要調試smack.jar 那麼創建的新文件名字爲 smack.jar.properties
新文件裏面包含兩行
第一行是代碼的關聯
第二行是文檔的關聯

補充：
1、源代碼文件支持 jar 和 zip 文件格式。
2、支持使用相對路徑指向原文件。
例如： dev 和 libs 是同級文件夾，libs裏面是jar，dev裏面是對應jar的源代碼。

文件加入後，重新啓動ADT，OK！
