Storage andTombstoning

DemoFast ApplicationSwitching

Application Lifecycle - Dormant Fast App Resume runningState preserved!e.IsApplicationInstancePreserved Save State!== true activated deactivated dormant Phone resources detached Threads & timers suspended Windows Phone

Application Lifecycle - Tombstoned Resuming .. .Restore state!e.IsApplicationInstancePreserved== false running activated deactivated Tombstone the oldest app Tombstoned dormant Phone resources detached Threads & timers suspended Windows Phone

Finding the Resume type private void Application_Activated(object sender, ActivatedEventArgs e) { if (e.IsApplicationInstancePreserved) { // Dormant - objects in memory intact } else { // Tombstoned - need to reload } } The Activation handler can test a flag to determine the type of resume taking place Windows Phone

Isolated Storage vs State Storage Isolated storage is so called because the data for an application is isolated from all other applications  It can be used as filestore where an application can store folders and files  It is slow to access, since it is based on NVRAM technology  It can also be used to store name/value pairs, e.g. program settings State storage is so called because it is used to hold the state of an application  It can be used to store name/value pairs which are held in memory for dormant or tombstoned applications  It provides very quick access to data Windows Phone 10

Fast App Switching andTombstoning Review Only one Windows Phone application is Active at any time The Start and Back buttons on the phone are used to start new applications and return to previously used ones If an application is replaced by another it is either made Dormant (still in memory but not running) or Tombstoned (removed from memory) Applications must use populate methods provided in the App.xaml.cs class to save and retrieve state information when appropriate  State can be stored in memory for quick reload and in isolated storage which serve as a permanent store Windows Phone 12

Alarms andReminders

Scheduled Notifications Time-based, on-phone notifications Supports Alarms & Reminders Persist across reboots Adheres to user settings Consistent with phone UX Windows Phone

Alarms vs Reminders? Alarms Reminder s• Modal • Rich information• Snooze and Dismiss • Integrates with other• Sound customization reminders• No app invocation • Snooze and Dismiss• No stacking • Launch app • Follows the phones global 15 settings

Creating a Reminder using Microsoft.Phone.Scheduler; ... eggReminder = new Reminder("Egg Timer"); eggReminder.BeginTime = DateTime.Now + new TimeSpan(0, eggTime, 0); eggReminder.Content = "Egg Ready"; eggReminder.RecurrenceType = RecurrenceInterval.None; eggReminder.NavigationUri = new Uri("/EggReadyPage.xaml", UriKind.Relative); ScheduledActionService.Add(eggReminder); This code creates a reminder and adds it as a scheduled service The value eggTime holds the length of the delay This code also sets the url of the page in the application Windows Phone

Reminder HousekeepingReminder eggReminder = ScheduledActionService.Find("Egg Timer") as Reminder;if ( eggReminder != null ){ ScheduledActionService.Remove("Egg Timer");} Reminders are identified by name This code finds the “Egg Timer” reminder and then removes it from the scheduler Windows Phone

Application Tiles

Tiles 101 Shortcuts to apps Static or dynamic 2 sizes: small & large  Large only for 1st party apps End-user is in control Windows Phone

Data Driven Template Model A fixed set of data properties Each property corresponds to a UI element Each UI element has a fixed position on screen Not all elements need to be used Animations are not extensible Background Title Count Image (173 x 173 .png) Windows Phone

Scenarios/Popular Applications Weather Apps  Send to WP7  Weather Tile  Link Tile  Warning Toast  Link Toast Chess by Post  AlphaJax  Turn Tile  Turn Tile  Move Toast  Move Toast Beezz  Seattle Traffic Map  Unread Tile  Traffic Tile  Direct Toast Windows Phone

Primary and Secondary Tiles Application Tile Front  Pinned from App List  Properties are set initially in the Application Manifest Back Secondary Tile  New in Windows Phone 7.5!  Created as a result of user input in an application Windows Phone

Live Tiles – Local Tile API Local tile updates (these are *not* push)  Full control of all properties when your app is in the foreground or background  Calorie counter, sticky notes Multi-Tile!  Deep-link to specific application sections  Launch directly to page/experience Windows Phone

Live Tiles – Local Tile APIContinued… Back of tile updates  Full control of all properties when your app is in the foreground or background  Content, Title, Background Content Content string is Background bigger Title Title  Flips from front to back at random interval  Smart logic to make flips asynchronous Windows Phone
