Android 4.0 SDK Tools 同步登場!

Android 4.0 SDK 是 Google Android 最新推出的應用程式開發工具套件包。
Android Developers 官方網站所示,對於 Android 應用程式開發者而言, Android 4.0 SDK 有以下七項重大關鍵的特色:
  • Android 4.0 SDK 為統一支援 Android 智慧型手機、Android 平板電腦與其它 Android 設備的應用程式開發套件。
  • Android 4.0 SDK 還具有新式的社群與日曆 API、以 NFC 為基礎的即時共享機制、支援 Wi-Fi Direct 、支援藍芽 HDP ( Bluetooth Health Device Profile ) 。
  • Android 4.0 SDK 還改進了訊息通知 ( notifications ) 機制、新推出具有相機與聲音控制的解鎖畫面、改進應用程式啟動機制 ( launcher ) 下的應用程式管理工作 ( app management )。
  • Android 4.0 SDK 還新推出了 圖片與影片的特效功能、精準的相機測光與人臉辨識功能、新式的媒體編碼機制 ( media codecs and containers ) 。
  • Android 4.0 SDK 還針對平面繪圖的硬體加速功能進行改善、新推出網格式版面元件 ( grid-based layout ) 、改善虛擬鍵盤 ( soft keyboard ) 、改善拼字檢查 API ( spell-checker API ) 、改善手寫辨識的輸入支援、以及改善滑鼠設備的支援。
  • Android 4.0 SDK 還新增了輔助功能的API、新式撰寫引擎的文字轉語音 API。
  • Android 4.0 SDK 也對於企業用戶的安全進行了增強改善。

除 Android 4.0 SDK 之外,這次 Android 也推出了新版的 SDK Tools (r14) and ADT Plugin (14.0) for Eclipse。
尤其是 ADT Plugin (14.0) for Eclipse 更大幅度地改善了 Android 應用程式的圖型化使用者介面設計開發編輯器。
最後,我們相信 Android 4.0 將會是 Android 推出至今最關鍵且重大的改版。這次的改版,不只帶給手機用戶更方便的功能。或許還能讓 Android 應用程式開發者看見更遼闊且美好的未來願景。
