Add a comment. Active Oldest Votes. Officially, no, there's no such thing. There are a few reasons for this: WP apps can't see other apps or indeed any process running outside the app's sandbox.

This is by design, as a security measure to keep a malicious app from spying on you or interfering with other apps. WP automatically suspends backgrounded apps. If the phone runs low on memory, suspended apps are "dehydrated" MSFT's term to persistent storage and then removed entirely this is part of why resuming an app sometimes takes a moment. There are only two kinds of apps that are allowed to run continuously in the background: Navigation apps like Here Drive.

Only one such app can run at a time; launching another will kill the first one. Age rating For all ages. Category Productivity.

How you found the violation and any other useful info. That way we can be sure that our task gets registered when it should, even if it's already in the list of tasks:. With the TaskHelper built, let's switch over to the MainPage. One important thing to keep in mind when registering background tasks is that you must request background access from the system by calling BackgroundExecutionManager. If the user is on Windows 8, they'll get a prompt asking them to give the app permission to run in the background and place it on the lockscreen.

If they deny either of these permissions, your app will not be allowed to run background tasks. We're going to check if the app has been updated — which will automatically remove background access as required for a Windows Phone app — and then request background access.

That way, the app will already be loaded in the background by the time we ask for background access. Notice when we request background access that we're able to check the answer by calling request. On Windows 8 the answer will be decided by the user when they choose to grant your app background access and place it on the lock screen. However, on Windows Phone the answer is going to be decided by the OS rather than the user.

A couple of things go into that decision, but the biggest factor is how many of the user's apps are running in the background already. The worst part?

There's nothing you can do about it. I've had brand new apps released on the Windows Phone store that were immediately denied background access because of battery concerns. ToString will always be 'Denied' when the app is not granted background access. At that point we'll show a new MessageDialog which informs the user that the app has no background access and how they can fix it. But what happens if background access is granted instead? If that's the case, the first thing we do is determine if we need to force register the new task.

We can do that by checking the phone's localSettings to determine if the app had background access the last time it ran. We'll take that forceRegister boolean and pass it to the TaskHelper that we recently created. The helper will determine if we need to create the task for the first time, if it needs to force register the task, or if the task is fine and nothing needs to happen. This process is largely the same for the Windows app, except that we do not need to check if the app has been updated first.

For reasons known only to Microsoft, we do not need to remove and then re-request background access when a Windows app has been updated — only Windows Phone apps have this requirement. You might be worried that we're requesting background access every time the page loads; doesn't that prompt the user to grant permission? Luckily, that won't be a problem. Windows will only prompt the user to grant background access once.

There's no danger of accidentally spamming them every time they open your app. However, we always want to know the current status of background access because our timer task is integral to the application. That's why we use RequestBackgroundAccess every time the page loads — so we can tell if our task is allowed to run. And there we go! Our app is now fully functional with background task swag. It displays a list of the latest 10 Jesse Cox videos, and it scans YouTube for new videos every 15 or 30 minutes.

Opening up the new class file should give you something like this: using System; using System. Generic; using System. Linq; using System. Text; using System. Storage; using Windows. Background; using ButterflyCore; using Windows. Notifications; using Windows. Instead, we need to use the task instance's deferral to specifically tell the task that it should wait until our async code is complete GetDeferral to prevent race conditions where the task finishes before async code completes.

Let's finish out the background task now by polling the YouTube API and showing a toast if there's been a new video GetElementsByTagName "image" [0].
