【環境建立】
-----for windows
一．下載且安裝 java JDK，需注意JAVA版本需大於1.5版 (命令行上輸入 java -version 來查看java版本) 。
   –安裝完之後可以java online account，有以下的好處：
   After you register your JDK, you will receive these benefits:
      •Notification of new versions, patches, and updates
      •Special offers on developer products, services and training
      •Access to early releases and documentation
      •Ability to track and manage your registered products and systems on our inventory site
  
  –建立環境變數：On Windows, right-click on My Computer, and select Properties. Under the Advanced tab, hit the Environment Variables button, and in the dialog that comes up, double-click on Path (under System Variables). Add the full path to the tools/ directory to the path.

二． 下載 Eclipse 且直接執行即可：Eclipse 是一個開發工具平台。注意選擇的版本需包含 JDT (Java Development Tool Plugin)，可以下載 3.6版 (Helios)、3.5版 (Galileo)。

三．下載ADT(Android Development Tools Plugin)：Android 開發工具擴充套件

Adding SDK Components

P.S. New platforms are automatically saved into the /platforms/ directory of your SDK; new add-ons are saved in the /add-ons/ directory; samples are saved in the /samples/android-/; and new documentation is saved in the existing /docs/ directory (old docs are replaced).

註：需要自動編譯的話，環境上則需要 Apache Ant 1.7 或之後版本。
