Samsung to Discard Windows

Phone

Samsung Electronics, the world’s No 5 smartphone manufacturer, plans to discard the WP7 OS to increase phones

on the Android platform and with its own

smartphone operating system

WP 7 growing popularity

 In the first 6 weeks phone manufacturers sold 1.5 million

Windows Phone 7 devices to mobile operators and retailers

 4th quarter of 2010 it had sold more than 2 million

 „Windows Phone 7 handsets are selling better than expected”

 T-Mobile USA said of WP7: "The customers are very satisfied with the experience We’ve done well with the devices that we sold”

 Many positive reviews

Windows Phone Developer Tools from Microsoft site for free

http://create.msdn.com/en-us/home/getting_started

Two WP dev frameworks

„The two frameworks, along Common Base Class Library provide a substantial number of

components for developers to construct applications on”

„Applications written for Silverlight or the XNA Framework today will run on Windows Phone with only a minor number of adjustments, such as for screen size or for device specific features”

 framework for creating Rich Internet Application style

UI

 with emphasis on multimedia, animations, graphics,

with features and purposes similar to those of Adobe

Flash

 Hardware accelerated by DX

 Started on mobile with WP7 and Symbian (series 60)

FOR:

 XAML based, event driven application framework

 rapid creation of a Rich Internet Application-style user

interface

 use Windows Phone controls

 embed video inside your application

 use an HTML web browser control

Silverlight and XNA

 Framework is focused on enabling game developers to be successful developing on Microsoft gaming platforms

 provides a complete set of managed APIs for game development

 platforms WP, Xbox 360, Zune HD, Windows OS

FOR:

 high performance game

 rapid creation of multi-screen 2D and 3D games

 manage art assets such as models, meshes, sprites, textures, effects, terrains, or animations in the XNA Content Pipeline

 Microsoft Expression Blend, UI desing tool (vector-based 2D widgets, and 3D widgets with hardware acceleration via DirectX), XAML-based

Developing – location

with varying levels of accuracy and power consumption

 On top of the hardware sits the native code layer which communicates

directly with the available sources of location data and decides which

sources to use to determine the location of the device based on the

availability of data and on the performance requirements specified by the application.

 layer also communicates over the Internet with a Microsoft-hosted web

service to look up location-related information from a database

 User can choose between high accuracy or the default, power-optimized setting

 „MovementTresholdProperty” to set desired minimum change in position

 „StatusChange” (disable, ready, noData, initializing) and „PositionChange” Event

 Even when the Location Service is able to obtain location data, initializing and obtaining the first reading typically takes 15 seconds, but can take up to

120 seconds

Developing – location - psudocode

using System.Device.Location // class import

…

GeoCoordinateWatcher watcher // variable declaration object

…

// Start the acquisition of data from the Location Service:

// eg Click the event handler for the “Start Location” button

private void startLocationButton_Click(object sender,

RoutedEventArgs e)

accuracy

watcher = new GeoCoordinateWatcher(GeoPositionAccuracy.High)

// use MovementThreshold to ignore noise in the signal

watcher.MovementThreshold = 20;

// Addind event handlers for the StatusChanged and PositionChanged events

watcher.StatusChanged += new

EventHandler<GeoPositionStatusChangedEventArgs>(watcher_StatusCha nged)

watcher.PositionChanged += new

EventHandler<GeoPositionChangedEventArgs<GeoCoordinate>>(watcher_ PositionChanged)

//start the Location Service

watcher.Start();

void watcher_StatusChanged(object sender, GeoPositionStatusChangedEventArgs e){

// The Location Service is disabled or unsupported

// Check to see if the user has disabled the Location Service

case GeoPositionStatus.Initializing:

// The Location Service is initializing

// Disable the Start Location button

case GeoPositionStatus.NoData

// The Location Service is working, but it cannot get location data

// Alert the user and enable the Stop Location button

case GeoPositionStatus.Ready:

// The Location Service is working and is receiving location data

// Show the current position and enable the Stop Location button

Developing - Accelerometer

„Accelerometer is a sensor that measures acceleration forces such as gravity

or the forces caused by moving the sensor All Windows Phones have at

least one accelerometer sensor that, when accessed by the managed

Accelerometer AP Ican be used to provide input to applications”

„It is built on top of a more general sensor framework so other sensors that

may be supported by Windows Phones in the future will be accessed in a similar way”

Imports: using Microsoft.Devices.Sensors

Declaration: Accelerometer accelerometer = new Accelerometer()

Ad event: accelerometer.ReadingChanged += new

EventHandler<AccelerometerReadingEventArgs>(acc_ReadingChanged)

Implemet event: acc_ReadingChanged( ) { Disp.Invoke => AccChanged(e) }

Event is raised when accelerometer has new data Event handler is called from different thread than the one in which page is running, then Dispatcher class has to be used to invoke method in page’s thread:
