How to start background task at boot - Windows Store app

Question

My tablet runs Windows 8.1 pro.

It has a background task which is triggered by a Time Trigger every 15'. It works, fair enough.

The problem is that I need to auto-launch my background task at every single boot (start app) of my device.

I registered my bg by this code:

       builder.Name = "bikePositionUpdate";
        builder.TaskEntryPoint = "BackgroundTaskGps.BikeGPSPositionUpdateBackgroundTask";
        builder.SetTrigger(new TimeTrigger(15, false)); // 

        // adding condition
        SystemCondition internetCondition = new SystemCondition(SystemConditionType.InternetAvailable);
        SystemCondition userPresentCondition = new SystemCondition(SystemConditionType.UserPresent); 

        builder.AddCondition(internetCondition);
        builder.AddCondition(userPresentCondition);
        BackgroundTaskRegistration taskRegistration = builder.Register();

my app has lock screen access

         await BackgroundExecutionManager.RequestAccessAsync();

How can I achieve this? Am I missing something?

Answer 1

You have to add the SystemConditionType.SessionConnected condition, this condition happen every time the user log on to Windows.

An app must be placed on the lock screen before it can successfully register background tasks using this trigger type.

Edit:

On this url you can find the official documentation about what you need, and how to use it:
