Tasks
Since Windows Phone platform does not allow multitaskingwe can only have a single application running.
In addition each application has its own private storage locationwhich other applications can not access.
Task in WP7 API is used to launch some of the built in
application, which offers snippet of functionality to performsome manipulations on the external resorces, built inapplications.
For Tasks we need a reference to Microsoft.Phone.Tasksnamespace.
NOTICE: some of them just plain dont work in WP emulator.
For example, the EmailComposeTask assumes you have an emailaccount set up on the device. Because the emulator prevents youfrom creating email accounts, you wont be able to test this.

Launchers
Launcher task can be described as fire-and-forgetmechanism.
There is no data or result returned by launcher.
We cannot say how the launcher task was finished by user!
Launchers have some general steps to launch the particularfunctionality and steps are as follows:
Creating an instance of the task
Setting the parameters to organize the task
Calling the show method to invoke the task

SMSComposeTask launches the Messaging application, and presents the userwith the ability to send a text message. You can specify recipients and message
body, but the user has to send it.
EmailComposeTask this task is used to send Email message, by Email
Composing screen with the options to load the data which we can be specified as
static or dynamic from code. The Email will not be sent unless and until the user

number and name. The phone call isnt dialed until the user presses Call.
WebBrowserTask launches the Web Browser, and navigates to the specified
URL.

to make use of some of the properties like rewind, pause, forward etc to make it
much easier to perform.

Choosers
Choosers are a little more complicated (than Launchers),because they return data to your application (where a
Launcher just gives the user a new task to accomplish).
Choosers have some general steps to launch a particular
application and steps are as follows: Creating an instance of the task
Identifying the callback method to run after the task completes
Setting the parameters to organize the task
Calling the show method to invoke the task
Implementing the completed event handler to get the data and
status.

Contacts API
With Choosers, we were able to prompt a user to select a recordfrom their list of contacts on their phone, and retrieve a specificpiece of data from that contact: an email address or a phonenumber, but not both at once.
With namespace
Microsoft.Phone.UserData(introduced in WP 7.5), we have the ability to treat the userscontact list like a local database.
We can search it, grab multiple contacts, and get their entirecontact record.
Its important to remember that the data we are accessing is READ-ONLY.
We cant make updates, delete anything, or even add anything.

Contacts API
Searching for data method Contacts.SearchAsync methodtakes three parameters:
stringthis is the search criteria youre using. In our example, its the
contents of the TextBox that we created in our XAML file.
FilterKindthis allows you to search only by PhoneNumber,
DisplayName, or EmailAddress. If you select None, your searchcriteria string will be ignored.
object this is an object parameter that you can use to pass data into
the search so that when you receive the results, you know something
about what you were trying to accomplish. This can be as simple as a
string identifier, all the way up to a specific object that youll needlater.
8/2/2019 WP7 Tpa 7 Choosers Launchers
13/20
Contacts API
What you can get (assuming its available in the Contactrecord): Accounts the list of accounts that this contact is associated
with. This includes things like Facebook, Windows Live, Outlook, etc.
Addresses the list of addresses for this contact. Each address alsoincludes the account (from above) that it is associated with, the
kind of address it is (like work, home, etc.), and finallyPhysicalAddress, which exposes all of the expected values likeAddress1, City, StateProvince, and CountryRegion.
BirthdaysIm not sure why a user would have different birthdays,but each account might have a different value, so you get alist. Also, if a year isnt specified, youll get a value of 1 for the yearin those cases.
Children a simple list of strings that represent the names of thechildren of the contact.
Companies again enriched with the accounts data, this includesvalues like JobTitle, CompanyName, and OfficeLocation.

Contacts API CompleteName shown in our code sample above, this contains all the
properties of a contacts name, including Title, Suffix, MiddleName, etc.
DisplayName a simple string that represents the name that is used onthe phone for this contact.
EmailAddressesa list of email addresses, with account and kinddata as well.
IsPinnedToStart this is an interesting piece of boolean data, because it
generally indicates which of this users contacts are the most importantto them (because the contact is pinned to the users start screen.)
Notes a list of strings that the user has saved as notes about thiscontact.
PhoneNumbers a list of all of the phone number associated with acontact, this is also decorated with accounts and kind data.
SignificantOthersyoud like to think theres only one value for this aswell, butyou know Anyways, this is similar to the Children property. Alist of strings.
Websites a list of the websites associated with this contact, stored asstrings.

Calendar API
With same namespace
Microsoft.Phone.UserData
we have the ability to treat the calendar data like a local
database.
Its important to remember that the data we are accessing isas well READ-ONLY.
We cant add new events to the users calendar, but we will be able to
see when they are available.

Calendar API
Searching for data method Appointments.SearchAsyncmethod takes three parameters:
StartDate a DateTime value that indicates the beginning of our
search. It is an inclusive value, so the time you indicate will also be
included in the search.
EndDate another inclusive value, it indicates the end time of oursearch.
State a user-defined object that you can pass to the search, and it
will be returned in the event handler, so that you can identify the
individual search. Simple applications like the one in this article will
likely use null for this value.

Device Information
Windows Phone devices meet a common hardwarespecification, but some provide additional features.
It is possible for an application to examine the device'scapabilities in order to alter its behavior to provide the bestuser experience.
WP SDK offers ability to retrieve information aboutcapabilities for: networking, hardware, and general deviceinformation such as manufacturer and firmware.
We can use the DeviceStatus class from
Microsoft.Phone.Info namespace, to retrieve deviceinformation.
It is a static class that enables an application to obtaininformation about the device on which it is running.
http://msdn.microsoft.com/en-us/library/microsoft.phone.info.devicestatus(v=vs.92).aspxhttp://msdn.microsoft.com/en-us/library/microsoft.phone.info.devicestatus(v=vs.92).aspx8/2/2019 WP7 Tpa 7 Choosers Launchers
19/20
Device Information
It exposes the following static properties through whichyou can get different device information: ApplicationCurrentMemoryUsage: Returns the memory usage of the current
application in bytes.
ApplicationPeakMemoryUsage: Returns the peak memory usage of thecurrent application in bytes.
DeviceFirmwareVersion :Returns the firmware version running on the device. DeviceHardwareVersion: Returns the hardware version running on the
device.
DeviceManufacturer: Returns the device manufacturer name.
DeviceName: Returns the device name.
DeviceTotalMemory: Returns the physical RAM size of the device in bytes.
IsKeyboardDeployed: Indicates whether the user has deployed the physicalhardware keyboard of the device.
IsKeyboardPresent: Indicates whether the device contains a physicalhardware keyboard.
PowerSource: Indicates if the device is currently running on battery power oris plugged in to an external power supply.
