WP 7 growing popularity


In the first 6 weeks phone manufacturers sold 1.5 million
Windows Phone 7 devices to mobile operators and retailers

with the experience. We’ve done well with the devices that we
sold”

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”

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

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()
