Windows Phone 7 and Windows Azure Development Tutorial COSC7388 Fall 2012 Huy Nguyen

What you should know in advance Object-Oriented Programming C# programming language and Microsoft Visual Studio IDE Basic knowledge on using smart phones If you need to learn C# and VS, take a look at http://www.csharpcourse.com/ http://www.learnvisualstudio.net/

Agenda 1. Windows Phone 7 development introduction Getting started with WP 7 Building a WP app Silverlight controls and integration services Tons of demos 2. Windows Azure platform What is Windows Azure? Project Hawaii Building WP application with Windows Azure Miscellaneous

Hardware foundation (WP 7.0) Capacitive touch 4 or more contact points Sensors A-GPS, Accelerometer, Compass, Light, Proximity, Camera 5 mega pixels or more 800 800 Multimedia Common detailed specs, Codec acceleration Memory 256MB RAM or more, 8GB Flash or more GPU DirectX 9 acceleration CPU Qualcomm MSM8x55 800Mhz or higher Hardware buttons Back, Start, Search 480

WP development process Tools Phone Emulator Samples Documentation Guides Community Packaging and Verification Tools myapp.xa p Windows Phone device Packaging & Verification Tools Windows Phone Emulator

Using Microsoft Marketplace Similar to Google Play or Apple App Store To publish apps, you need to reg as a developer Costs 99 per year Unlimited fee apps Up to 5 free apps ( 20 each additional) Student can signup for free via Dreamspark Revenue sharing – 30/70

Two flavors of applications Modern XAML/event-driven application UI framework Rapid creation of visually stunning apps Metro-themed UI controls HTML/JavaScript 500,000 developers spanning Windows and web High performance game framework Rapid creation of multi-screen 2D and 3D games Rich content pipeline Mature, robust, widely adopted technology spanning Xbox 360, Windows, and Zune

Things to remember You are developing for a small device Decisions you make about your application can have an impact on user experience and phone battery life The power is amazing for such a small device But it is not the same as a desktop or laptop Always test your app on real devices (not on your emulator powered by an i7 CPU) Code clean and code smart

Building a WP application

Silverlight project types Windows Phone Application – a basic single page application Windows Phone Databound Application – using List and Navigation controls Windows Phone Panorama Application – support panorama mode Windows Phone Class Library – a library for shared logic with no pre-build UI

Silverlight controls Silverlight control set is rich Familiar to existing Silverlight and .NET developers Some additional features For example, Software Input Panel support on TextBox

Creating our first application Code is available at http://www2.cs.uh.edu/ rzheng/course/COSC7388fa12/

Application bar and system tray System Tray No integration, but does affect Layout Show:Hide using SystemTray.IsVisible Application Bar Up to 4 Buttons Menu Items (Recommended 6) Toggle Visibility mypage .ApplicationBar.IsVisible

Panorama Part of the native Windows Phone look and feel Panorama is a long horizontal canvas PanoramaItem serves as a container that hosts other content and controls

More controls Standard Controls Buttons, Image, Layout, ListBox, TextBox, Slider, Other Bing Maps Bing Map Control, Integration with Bing Maps Services Deep Zoom Included in core run-time, Optimized to take advantage of GPU, Consumes same content as SL on desktop, Supported for Online content Web Browser Displays network and local content, Supports pan, double tap and pinch to zoom, Supports transforms & projections, Application can interact with javascript

Sensors on your smart phone Y Audio sensor (microphone) Image sensor (camera, video recorder) -Z -X X Tri-Axial Accelerometer Z -Y Location sensor (GPS, cell tower, WiFi) Proximity sensor (infrared) Magnetic compass Gyroscope Light sensor Temperature sensor

Sensors mining and sample applications Activity recognition (Walking, Jogging, Climbing Stairs, Lying Down, Sitting, Standing) Fall/movement detection Biometric identification Location-based applications Social networking applications Voice-activated systems

Background agents (7.1 SDK) Execute code in the background Two types of tasks Scheduled tasks are limited to run only part of the APIs

A location-aware application Code is available at http://www2.cs.uh.edu/ rzheng/course/COSC7388fa12/

Windows Azure Service Platform

What is cloud computing? The use of computing resources (hardware and software) that are delivered as a service over a network (typically the Internet) The name comes from the use of a cloud-shaped symbol as an abstraction for the complex infrastructure it contains in system diagrams

Cloud service classification Consume Software as-a-Service Build Platform as-a-Service Host Infrastructure as-a-Service

Why phone and cloud? Phone Connected Pervasive Marketplace Cloud Common endpoint Scalable Utility billing

Why WP7 and Windows Azure? Common development tools Emulator for development Complementary application models Phone: sometimes on, connected Cloud always available, running

Microsoft Project Hawaii New effort to investigate the ability of the cloud to enhance end-user experience on mobile devices Unleash the creative power of students System & networking infrastructure for writing cloud-enhanced mobile applications Software platform & materials to enable university Profs to offer courses in “mobile cloud”

Hawaii cloud services Path Prediction Service This service enables a mobile application to predict a user’s destination based on current route data. Translator Service This service provides an interface to Microsoft Translator. Relay Service This service provides a relay point in the cloud that mobile applications can use to communicate. Optical Character Recognition (OCR) Service This service takes a photographic image that contains some text and returns the text. Speech-to-Text Service This service takes a spoken phrase and returns text (currently in English only).
