Extended execution in UWP

问题

I want to use a background task for my UWP app.

The below code, is my back button click event in windows mobile-

private async void MainPage_BackRequested(object sender, BackRequestedEventArgs e)
{
   var access= await BackgroundExecutionManager.RequestAccessAsync();
    var task = new BackgroundTaskBuilder
    {
        Name="My task",TaskEntryPoint=typeof(backGroundTask.Class1).ToString()
    };
    trigger = new ApplicationTrigger();
    task.SetTrigger(trigger);
    task.Register();
    //var result = await trigger.RequestAsync();
    if (Frame.CanGoBack)
    {
        Frame.GoBack();
        e.Handled = true;
    }
}


public void Run(IBackgroundTaskInstance taskInstance)
{
    _deferral = taskInstance.GetDeferral();
    clearData();
    count1 = 0;
    getDownloadedSongs();

    dispatcherTimer1.Tick += DispatcherTimer1_Tick;
    dispatcherTimer1.Interval = new TimeSpan(0, 0, 3);
    dispatcherTimer1.Start();
    _deferral.Complete();



}
DispatcherTimer dispatcherTimer1 = new DispatcherTimer();

 private async void DispatcherTimer1_Tick(object sender, object e)
{

    try
    {
          clearData();

    }
    catch (Exception ex)
    {
    }
}

回答1:

ExtendedExecution will allow you to keep running and finish your task before you get suspended. Please take a look at the official sample for ExtendedExecution

回答2:

Extended Execution has been in talks for quite a long now. You can definitely continue the app execution even when it is minimized. I don't have a working sample yet but you can get some insight by looking at the link here
