Helping Lions Roar with Microsoft Win8 & WP8 Apps

- 2. Intro For the next 17mins- ish we want to discuss the mobile market today and how the mobile user is changing. We will also touch upon the opportunity that Windows 8 & Windows Phone 8 brings to this key channel and your brands. However our main focus will be to showcase the upcoming release of the Official application for the British & Irish Lions. so lets begin…. First up
- 7. The brief Create a multi-platform application that works on desktop, tablet and mobile. Excite fans with a slick application experience and exclusive content centered around this year’s tour. Integrate with 3rd party APIs to provide real time information.
- 12. SolutionArchitecture • App content & structure controlled via CMS • Apps fully functional offline • Cache pre-populated with content/images fromAzure when building apps
- 13. Lions app core
- 14. Lions app core
- 15. Lions app core • Uses the IoC built in to Mvx to implement a SOA (Service OrientatedArchitecture) approach • Allows for components to be swapped in / out easily – Fake data source – Different caching strategies – Unit Testing / Mocking
- 16. Customizing MvvmCross • Overriding Mvx components to do non “out-of-the- box” stuff • Adding custom cross-platform services
- 17. Customizing MvvmCross – Overriding Components
- 18. Customizing MvvmCross – Overriding Components • App.cs (our MvxApplication in our PCL) • This approach gets really messy really quickly… //Inject our own image caching into Mvx Cirrious.MvvmCross.Plugins.File.PluginLoader.Instance.EnsureLoaded(); var imageFileCache = new LionsImageCacheService(………); this.RegisterServiceInstance<IMvxFileDownloadCache>(imageFileCache);
- 19. Customizing MvvmCross – Overriding Components • Plugin Manager public class DroidPluginManager : MvxFileBasedPluginManager { public DroidPluginManager() : base("Droid") { } protected override Cirrious.MvvmCross.Interfaces.Plugins.IMvxPlugin LoadPlugin(Type toLoad) { if (toLoad == typeof (Cirrious.MvvmCross.Plugins.DownloadCache.PluginLoader)) { return new LionsCachePlugin(); } return base.LoadPlugin(toLoad); } public class LionsImagePlugin : IMvxPlugin { public void Load() { //Do exactly what the Mvx plugin does, except load our custom service instead } } }
- 20. Customizing MvvmCross – Cross-platform services • Providing images from the app package – a platform specific task • In the core: var packageProv = this.GetService<IPackagedImageProvider>(); var fileName = packageProv.GetPackagedImageFileName(httpSource); if (!String.IsNullOrEmpty(fileName)) { packageProv.CopyPackagedImage(fileName, (succeeded) => { … }); }
- 21. Customizing MvvmCross – Cross-platform services • In Windows 8 Setup: protected override void InitializeFirstChance() { this.RegisterServiceInstance<IPackagedImageProvider>( new Win8PackagedImageProvider()); base.InitializeFirstChance(); }
- 22. Customizing MvvmCross – Manual Navigation • Using some Mvx services to navigate when we’re not in a view model var myParams = new { nodeId }.ToSimplePropertyDictionary(); var req = new MvxShowViewModelRequest( viewModelType, myParams, true, MvxRequestedBy.Bookmark); this.GetService<IMvxViewDispatcherProvider>().Dispatcher.RequestNavigate(req);
- 23. Challenges
- 24. Multi-platform challenges • Cross training • Design / UX consistency • Content • ViewModel design • PCLs • MvvmCross
- 25. Windows Phone • Emulator requires specific hardware • Android emulator animosity • Supporting WP7 and WP8
- 27. iOS challenges • Interface Builder • PCL support • Slow store publishing
- 28. Android • Fragmentation • Windows Phone emulator animosity • Slow/unreliable emulator • Memory leaks (InPurgeable)
- 29. Android (continued) • Xamarin.Android – Slow debug cycle – Crashes & hangs – Debugging PCLs – Layout IntelliSense – No layout validation on PC – VS unhelpful error reporting for layouts/resources
- 30. Kindle • It’s just Android!
