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

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”


Silverlight and XNA







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

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:


Developing – location

GPS, Wi-Fi, cellular radio are hardware in WP as providers of location data
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)
{
// using high
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
EventHandlerPositionChanged)
//start the Location Service

watcher.Start();
}

if (e.Status == GeoPositionStatus.Ready)
{
// get the current location
GeoCoordinate co = watcher.Position.Location;
// optionaly Stop the Location Service to conserve battery power.
watcher.Stop();
}
}

Event handler for StatusChanged
void watcher_StatusChanged(object sender, GeoPositionStatusChangedEventArgs e)
{
switch (e.Status)
{
case GeoPositionStatus.Disabled:
// 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:
AccChanged(AccelerometerReadingEventArgs e)
{
get acc data
}
Run:

accelerometer.Start()
