Android程式授權。強悍還是恐怖？

開啟android的developer首頁，http://code.google.com/intl/zh-CN/android/，最顯眼的位置寫著“應用程式實在平等的條件下建立的”，這是多少J2ME開發人員夢寐以求的待遇。長久以來MIDP的程式都被當作二等公民看待，孱弱的KVM只能讓你畫個介面、連個HTTP/Socket之類的，這樣弱智的API讓你只能做點手機遊戲、網路記事本之類聊勝於無的東西。你想操作通訊錄？簡訊？電話記錄？洗洗歇了吧，諾、摩、索、蘋都不會理你的。那樣的開放性也只有在今天的android平台上才出現端倪。越來越強大的手持功能，應該留給開發人員和使用者更多的利用空間，發揮他們潛在水下那90%的強悍能力。
