Charms
www.netcomlearning.com
•Windows 8 has five charms:• Search: Look for files, settings, and apps on the computer, as well as search within apps• Share: Share content between apps• Start: Suspends active app and displays the Start screen• Devices: Send data and documents to external devices• Settings: View app information and change preferences
Contracts
• A Windows 8 contract is an agreement between the app and Windows– Apps that implement contracts make use of
operating system support• Contracts are declared in the app manifest,
Package.appxmanifest• Simplifies interactions between apps– Abstracts the implementation details of other apps– Reduces the number of integration scenarios

The Search Contract
www.netcomlearning.com
•Users can search your app from the Search pane if you implement the Search contract• Add Search to the list of declarations in the app manifest
• Apps can provide search query suggestions and result suggestions
Search Suggestions
www.netcomlearning.com
• Search suggestions help users discover what your app has to offer• Search suggestions are auto-
completions of the query• Result suggestions are direct links
to an app page
• Only the first five suggestions are shown in the search pane
Search Activation
www.netcomlearning.com
• The app is chosen from the search pane• This is called main view activation because the app is in the
foreground
• The app’s constructor is called, but OnLaunched is not• Add event listener to the activated function in your WinJS.Application object
Share Source Contract
www.netcomlearning.com
Source App
Share Broker
Target App
Registers DataRequested event handler with the DataTransferManager
Receives event and fills DataPackage in event handler
The user selects “Share.” The active app is sent a DataRequested event
Filters list of target apps and QuickLinks
Processes the contents of DataPackage
User selects target app or QuickLink
Activates the target app in a hosted view
Reports CompleteRecords a QuickLink if the target app returned one
Activated for sharing
DataPackage lives in source app
At installation, registers as ShareTarget
through manifest declaration
Windows 8 provides a framework for apps to share content with other apps
The Share Target contract is declared in the manifest, unlike the Share Source contract.
Shared Data Types
• Supported data formats are: text, URI, bitmap, HTML, StorageItems, and RTF– By using StorageItems you can transfer objects of
any class that implements the IStorageItem interface, including files
• You can share with a custom format– You are responsible for converting objects to byte
streams and back (serialization/deserialization
www.netcomlearning.com
The Share Target Contract
• To be listed in the Share pane, an app must declare itself a Share Target in the manifest
• The app must support at least one data format or file type
• The app must provide a sharing UI
www.netcomlearning.com
Share Target Activation
• Share target activation means that the app must supply a hosted view UI
• In the ready event handler, you should check the activation type:– Windows.ApplicationModel.Activation.Activation
Kind.shareTarget activation type indicates that the app was activated for share
– The options parameter of the ready function will contain the shareOperation object which contains all shared data

Updating Tiles Locally

<tile> <visual> <binding template="TileWidePeekImageCollection03"> <image id="1" src="image1.png" alt="alt text"/> <image id="2" src="image2.png" alt="alt text"/> <image id="3" src="image3.png" alt="alt text"/> <image id="4" src="image4.png" alt="alt text"/> <image id="5" src="image5.png" alt="alt text"/> <text id="1">Lorem ipsum dolor Ame Consectetur adipiscing</text> </binding> </visual> </tile>
Badge Notifications
www.netcomlearning.com
Number of unread email messages
Number of apps awaiting download
Numeric badge
Glyph badge
Creating a Badge Notification
var badgeXml = Notifications.BadgeUpdateManager.getTemplateContent(Notifications.BadgeTemplateType.badge Number); var badgeAttributes = badgeXml.getElementsByTagName("badge"); badgeAttributes[0].setAttribute("value", "58"); // Create a badge notification from the XML content. var badgeNotification = new Notifications.BadgeNotification(badgeXml); // Send the badge notification to the app's tile. Notifications.BadgeUpdateManager.createBadgeUpdaterForApplication().update(badgeNotificat ion);

Application UI
• Use the application UI section to customize basic visual features of the app– Basic information
• Display name, description, language– Tile
• Background images for three tile sizes• Background color
– Notifications• Toasts, lock screen notifications
– Splash screen• Image file or image resource• Background color

Capabilities Section
• The Capabilities section defines which system features or devices Windows allows your app to use– Internet (client, client and server)– User’s documents, pictures, music, and video libraries– Webcam and microphone– Location information– Removable storage
• Check only capabilities that your app requires• Special capabilities are available only to apps published under
company accounts• General capabilities are available to every account
www.netcomlearning.com
Declarations Section
• Declarations section defines specific functionalities that your app provides– Contracts are functionalities that your app declares it provides when
interacting with other apps• Cached file updater, file open picker, file save picker, search, share target
– Extensions are functionalities that your app declares it provides when interacting with Windows• AutoPlay, camera settings, contact picker, game explorer, and more
– Declarations have properties that describe their use by the app• Some are required for the project to build
www.netcomlearning.com
Packaging Section
• Packaging section lets you specify the identity of the app– Name and display name– Store logo
• Represents the app in the Windows Store
– Version• [Major].[Minor].[Build].[Revision]
– Certificate• Test certificate automatically generated by Visual Studio• Store certificate generated when packages are created for
upload to the store
– Publisher display name

The Windows Store
• Submitting apps to the Windows Store requires a Windows Store developer account– Annual payment required to remain active– Linked with a Microsoft account– Two kinds of developer accounts
• Individual• Company
• Manage your store account and app submissions on the dashboard– Update your developer profile, submit apps, view and edit apps in
progress, view and update apps in the store, explore store trends, and view a financial summary
www.netcomlearning.com
The Publishing/Certification Process
• Use the Windows Store dashboard to submit apps for certification and publishing– Complete all parts of the submission: app name,
selling details, advanced features, age rating and rating certificates, cryptography, packages, description, and notes to testers
• Before submitting an app for certification– Make sure that the app meets all requirements for
a Windows Store app– Check technical compliance by using the Windows
app Certification Kitwww.netcomlearning.com
Store Certification Requirements
• Windows Store apps must meet some minimum requirements to be accepted for publishing
• Generally, apps must:– Provide value to the customer– Be more than just ads or websites– Behave predictably– Put the customer in control– Be appropriate for a global audience– Be easily identified and understood
• This is an incomplete list. Not meeting any requirement will result in certification failure.
www.netcomlearning.com
Store Tools
• Visual Studio provides store tools to help with app publishing– Found on the STORE menu or by right-clicking a project and
selecting the Store submenu– Most important options are Associate App with the Store
and Create App Packages• Associating an app with the store links the project on a
development computer with the store’s app submission• The app package is the .appxupload file that has the correct
certificate so that you can upload to the store
– Other options help with your developer account, reserving app names, capturing screen shots, and uploading packages to the store
