4. Concept
Windows Phone SDK 7.1 Architecture
Runtime, Tools, Cloud Services, Portal
Services
Application Development Lifecycle

5. Architecture – 1/2

6. Architecture – 2/2
Runtime

Tools
– Visual Studio, Expression Blend
Cloud Services
– Windows Azure, XBOX Live, Notification
Services, and Location Services, …
Portal Services
– Windows Phone Marketplace

7. Runtimes

8. Application Development Lifecycle

9. Silverlight & XNA Framework
Silverlight
– 適用開發應用程式類的App，也可以開發遊戲
– WP與Windows在Silverlight的不同
• Implementation Differences Between Silverlight and
Silverlight for Windows Phone
XNA
– 適用開發遊戲與多媒體應用程式
究竟該開發那一種與選擇Framework
• The Silverlight and XNA Frameworks for Windows
Phone

10. Execution Model – 1/6
Windows Phone應用程式的生命週期
類型
– Application State
– Application Events
– Page State
– Page Events
– Tombstoning
– State Dictionaries

11. Execution Model – 2/6
Application
– Data that is used by multiple pages in an
application.
Page
– The current visual state of a single application
page.
Page Page Page
Application

12. Execution Model – 3/6
Application Events
– Launching
– Deactivated
– Activated
– Closing
Page Events
– PhoneApplication Page
• OnNavigatedTo
• OnNavigatedForm

13. Execution Model – 4/6
Tombstoning (墓碑)
– 應用程式久未使用或被回收，非走Closing離開
程式，應用程式被視為墓碑
– App裡的所有資源被回收
Terminated (休眠)
– 應用程式從前景換到背景，未被回收時，視為休
眠模式 (或稱暫停)
– 資源仍存在，回到App時可以繼續使用
搭配Deactivated與Activated
Reference: Windows Phone 7 - 簡介新運作模式 - Dormant

14. Execution Model – 5/6
Deactivation
– 代表App將由前景轉換背景模式前的事件
– 保存Page或Application中必要的資料
Activation
– 代表App由背景轉換前景時的事件
• 背景轉前景與由Start再啟動App完全不同
– iOS / Android 二個視為相同
– 還原必要資料至Page或Application

16. Page之間的切換 – Navigation – 1/2
PhoneAlicationFrame
– 一個Application有一個Frame
– 工作
• PhoneApplicationPage之間的資料交換
• 結合App.xaml控制ApplicationPage內的內容與控件
• 控制PhoneApplicationPage的切換
PhoneApplicationPage
– Application呈現的單位，UI控件的集合處
References: Navigation Framework原理概論

17. Page之間的切換 – Navigation – 2/3
關聯模塊

18. Page之間的切換 – Navigation – 3/3
Page切換原理

19. Isolated Storage – 1/3
Application專屬儲存區
– Sandbox機制，每個App具有獨立的I/O空間
– App之間無法交換資料
– 無法辦法直接訪問File System取得資料
– 提高安全性，降低未經授權的訪問和數據損壞的
可能性

20. Isolated Storage – 2/3
Data Storage Options

21. Isolated Storage – 3/3
Special-use Folders
Path Use Note
Shared 管理Media、ShellContent與 App安裝時自動建立，可
Transfer三個資料夾。 被刪除。
Shared/Media Album Art：App利用該資料夾呈 App安裝時自動建立，可
現Album Art，配合Background 被刪除。常搭配多媒體應
Audio一起使用。 用時，儲存媒體資料。
Shared/ShellContent Application Tiles: 用於呈現每個一 App安裝時自動建立，可
Tile在Font/Back的底層資訊，配 被刪除。配合Live Tiles時
合Live Tiles時使用。 使用。
Shared/Transfer Background file transfer:用於存放 App安裝時自動建立，可
背景下載的檔案，配合 被刪除。配合Background
Background Transfer元件使用。 Transfer元件使用。
– 也可依需求建立自訂的目錄結構

22. Isolated Storage vs. XAP
Isolated Storage
– App安裝後所產生的儲存區
XAP Resource
– XAP為App實際安裝檔
• 與Android中的Assets相似
– 可在應用過程裡，直接將XAP中的資訊Copy至Isolated
Storage進行操作
– XAP裡的資料是不可以修改
– XAP中的資料隨著專案打包時
• Content 與 Resource包裝上的差異
Reference: Windows Phone 7 – TitleContainer.OpenStream與App.GetResourceStream - 讀取XAP內資源的方法

23. Local Database – 1/2
Architecture
– DataContext
• 輕量的Entity Framework
– 沒有工具，要描述一個DB，全部要手動建立
– LINQ to SQL Runtime
• 所有的交易一律透過OR Mapping，沒有SQL
References: Windows Phone 7 – Local Database概論 - 2

24. Local Database – 2/2
Supported Properties
– data source : isostore/appdata
– password : 40 characters
• AES-128, SHA-256
– max buffer size: 384~5120 (kilobytes)
– max database size: 32~512 (megabytes)
– mode
• read write/read only/exclusive/shared read

25. Live Tile – 1/3
Tile
– WP獨特的概念元素，可呈現App資訊、互動項
目與通知內容
– 搭配Push Notification、Schedule排程等，動態
的調整Tile的內容
– Tile的動態特效，由系統控制，到了WP8有更豐
富的呈現機制

26. Live Tile – 2/3
Application Tile
– The font of a tile
– Only one
Secondary Tiles
– The back of a tile
– User can custom
References: Windows Phone 7 - 學習新的Secondary Tile與Application Tile

27. Live Tile – 3/3

– ShellTile APIs
• Application Tile and Secondary Tiles can be created,
updated, and deleted
– Tile Notifications
• Tile properties can be updated by using the Microsoft
Push Notification Service
– ShellSchedule APIs

updated on a recurring schedule, even if your
application is not running.

28. Controls & Toolkits
Controls
– Supported Controls in Windows Phone
Silverlight for Windows Phone
– Silverlight for Windows Phone Toolkit
Unsupported controls
– ComboBox, TreeView, OpenFileDialog, …

29. Chooser & Launcher
Launchers and Choosers Overview for
Windows Phone
Chooser
– 呼叫系統內部應用程式，並有回傳值
– Choosers for Windows Phone
Launcher
– 呼叫系統內部應用程式，執行固定任務
– Launchers for Windows Phone
References: Windows Phone 7 - 更多元的Microsoft.Phone.Tasks

30. MultiTask – 1/2
Background Agent
– 獨立於App之外的特殊背景元件
• 建置時屬於不同的專案
– Android, iOS中不具有該類項目，但各自有對應的背景機制
– 與App之間無法直接溝通
• 統一透過Isolated Storage進行資料交換
Lifecycle
– 一個App只有一個Agent
– NotifyComplete(), Abort()
– ScheduleToast

31. MultiTask – 2/2
Background Transfer
– 提供佇列一至多個檔案在背景下進行上傳、下載
Background Audio
– 支援App在非前景下仍可以播放音樂
Background Schedule Tasks
– 支援安排App在背景時可以處理特定的任務
• Periodic Task
– 適用執行較短時間的任務，執行隔間具有規律週期性
• Resource-intensive Task
