  1. 1.
  2. 2. Rudi Grobler<br />http://www.rudigrobler.net<br />@rudigrobler<br />An end-to-end experience of Windows Phone 7 development<br />TRACK: NEXT GENERATION<br />
  3. 3. agenda<br />Two part session<br />The basics<br />Build app from File -> New…<br />Advanced tips and tricks<br />Loads of content<br />Caveat: this is NOT a marketing session on how cool the phone is… This is how to build a application end-to-end<br />Feel free to ask questions ANY time...<br />Windows Phone 7 App Smackdown<br />
  4. 4. applications<br />Omoplata<br />Scrumy7<br />Podium<br />Professional Audio Recorder<br />7MC Gofer<br />Brew Master<br />
  5. 5. Brew Master<br />demo<br />
  6. 6. hardware foundation<br />Capacitive touch<br />4 or more contact points<br />Sensors<br />A-GPS, Accelerometer, Compass, Light, Proximity<br />Camera<br />5 mega pixels or more<br />Multimedia<br />Common detailed specs, Codec acceleration<br />800<br />Memory<br />256MB RAM or more, 8GB Flash or more<br />GPU<br />DirectX 9 acceleration<br />CPU<br />Qualcomm MSM8x55 1Ghz (800Mhz) or higher<br />480<br />Hardware buttons | Back, Start, Search<br />Qualcomm MSM7x30 & Gyroscope<br />
  7. 7. common platform capabilities<br />.NET<br />Superset of Silverlight 3.0<br />Input<br />Touch<br />Hardware buttons<br />Media<br />Digital media capture & playback<br />Media library access<br />Data<br />Isolated storage<br />LINQ<br />Object<br />XML<br />WCF<br />SOAP & REST services<br />Phone Access<br />Integrated access to phone UI<br />Sensors<br />Pickers for contacts and photos<br />Integrated with Cloud Services<br />App deployment & Updates<br />Notifications<br />Location<br />Xbox LIVE<br />
  8. 8. Two flavours of applications<br />Silverlight<br />XNA<br />Modern XAML/event-driven application UI framework<br />Rapid creation of visual stunning applications<br />Metro-themed UI controls<br />500,000 developers spanning Windows and web<br />High performance game framework<br />Rapid creation of multi-screen 2D & 3D games<br />Rich content pipeline<br />Mature, robust, widely adopted technology spanning Xbox 360, Windows and Zune<br />XNA/Silverlight Interop<br />
  9. 9. silverlight for windows phone<br />Silverlight for Windows Phone is…<br />Silverlight 3<br />minus a few things that didn’t make sense<br />plus a few Silverlight 4 things that did<br />plus phone specific API & “under the hood” improvements<br />Silverlight 4 compatibility (1500+ new APIs)<br />
  10. 10. Getting started…<br />demo<br />
  11. 11. navigation<br />Applications are built like web sites<br />Functionality is split into pages<br />Forward navigation via links<br />Backward navigation via Back<br />Previous applications (pages) are in the back stack<br />Can override back button behavior (but be careful)<br />Transient pages<br />Payload can be send with navigation request<br />NO back to home buttons!!!<br />Deep linking<br />
  12. 12. Navigation<br />demo<br />
  13. 13. familiar web concepts<br />Phone application<br />Provides UI represented as XAML pages connected into cross-app flows by URI’s<br />Web application<br />Provide media represented as HTTP resources linked by URL’s<br />Shell frame<br />Requests pages, renders UI, and handles navigation across apps<br />Web browser<br />Requests HTTP resources, renders them, and handles navigation across sites<br />History and tabs<br />Groups together sequences of HTTP resources corresponding to a user’s activity across sites<br />Sessions and back stack<br />Groups together sequences of pages corresponding to a user’s activity across apps<br />
  14. 14. launchers and choosers<br />Windows Phone execution model isolates every application in its own sandbox<br />Apps cannot directly access information stores such as contacts<br />Cannot directly invoke other applications such as phone or messaging<br />Launchers and Choosers allow applications indirect access to the useful phone features<br />Launchers and Choosers APIs invoke distinct built-in applications that replace the currently running applications<br />
  15. 15. launchers and choosers<br />Launcher<br />Launches one of the built-in applications though which a use completes a task<br />No data is returned to calling application<br />Example: PhoneCallTask<br />Chooser<br />Launches one of the built-in applications through which a user completes a task and which returns some data to calling application<br />When caller completes, calling application is activated and supplied with the Chooser result<br />Example: PhotoChooserTask<br />
  16. 16. launchers and choosers<br />Launchers<br />Choosers<br />EmailComposeTask<br />MediaPlayerLauncher<br />PhoneCallTask<br />SearchTask<br />SMSComposeTask<br />WebBrowserTask<br />MarketplaceDetailTask<br />MarketplaceHubTask<br />MarketplaceReviewTask<br />MarketplaceSearchTask<br />CameraCaptureTask<br />EmailAddressChooserTask<br />PhoneNumberChooserTask<br />PhotoChooserTask<br />SaveEmailAddressTask<br />SavePhoneNumberTask<br />Bing<br />
  17. 17. Launchers and Choosers<br />demo<br />
  18. 18. choosers and the execution model<br />IMPORTANT! When you launch a Launcher or Chooser, your app is terminated<br />When task completes, your app may be reactivated and a new app instance created (SOMETIMES)<br />The following choosers and tasks have relaxed thombstoning policy<br />PhotoChooserTask<br />CameraCaptureTask<br />MediaPlayerLaunchTask<br />EmailAddressChooser<br />PhoneNumberChoose<br />
  19. 19. panoramas<br />
  20. 20. panoramas<br />
  21. 21. pivots<br />
  22. 22. panorama vs pivot<br />Pivot<br />Panorama<br />Filter same data on different views (the “inbox” is a great example of this) <br />Optimized for current screen size <br />Filter of data doesn’t have to be same view (agenda/day) <br />Related content is ok to pivot on as long as related content is truly related <br />Focused <br />“Virtualized”<br />Horizontal broad canvas, not confined to current screen size <br />A ‘top layer’ view into underlying experiences/tasks <br />Use white space <br />Performance -> Panorama loads all the pages on startup<br />Exploratory in nature<br />
  23. 23. Adding and using the Pivot<br />demo<br />
  24. 24. misuse of common controls<br />Use the WP7 common controls appropriately.<br />Don’t use sliders, toggles or map controls under panoramas or pivots –as they both need the same gestures to work.<br />
  25. 25. MVVM on the Phone<br />Singleton<br />App.xaml<br />Model<br />PhoneApplicationPage<br />ViewModel<br />PhoneApplicationPage<br />PhoneApplicationPage<br />PhoneApplicationPage<br />View<br />Data<br />Bindable properties<br />Business logic<br />PhoneApplicationFrame<br />PhoneApplicationPage<br />Controls<br />Code-behind<br />Wanna learn more? <br /> Check out Silverlight Kung-fu<br /> Starting 16:30 @ track 3<br />
  26. 26. MVVM phone style…<br />demo<br />
  27. 27. networking on the phone<br />Support for networking features<br />WCF/ASMX<br />HttpWebRequest<br />WebClient<br />No cross-domain policy file required<br />Not supported<br />Sockets<br />Custom WCF Bindings<br />WCF RIA Services<br />NTLM authentication<br />
  28. 28. WCF/ASMX services<br />Can “Add Reference” from Windows Phone projects to automatically generate proxy classes<br />ASMX should just work<br />WCF requires that you use basicHttpBinding<br />
  29. 29. OData<br />Server:<br />WCF Data Services provides an extensible tool for publishing data using REST based interface<br />Publishes and consumes data using Odata web protocol <br />Format is XML or JSON<br />Client:<br />Download Odata Client Library for Windows Phone<br /> http://odata.codeplex.com/<br />FULL parity with Silverlight (Including LINQ and Add Service Reference support)<br />
  30. 30. Getting data<br />demo<br />
  31. 31. HTTPWebRequestvsWebClient<br />Use HttpWebRequest whenever possible<br />Use background thread and marshal back to UI thread (Using Dispatcher.BeginInvoke)<br />WebClient is “easier” to use but happens on the UI thread no matter where it was spawned (Bug)<br />6 Parallel requests limit<br />WebClient bug fixed<br />
  32. 32. marketplace<br />Enhanced Discovery<br />Easy to find great applications & games<br />Fun to browse the marketplace<br />Simple & Reliable Acquisition<br />Try before you buy<br />Buying and downloading content is a breeze<br />Payment flexibility (Monthly billing and credit card)<br />Easy application updates<br />South Africa WILL BE supported…<br />
  33. 33. marketplace<br />It costs nothing to download the Windows Phone SDK and write code using the emulator<br />To sell applications you need to register as a developer<br />This costs $99 a year and <br />allows you to publish any <br />number of fee applications <br />and up to 99 free applications<br />Each additional application <br />costs $20<br />Students can sign up for free<br />Revenue sharing (30/70)<br />
  34. 34. yalla apps<br />Are you looking for a viable alternative to publish your WP7 Apps to the Windows Phone Marketplace?
