Description

What would you like to be added:

Simple timer app activation, i.e. var builder = new Windows.ApplicationModel.Background.BackgroundTaskBuilder(); builder.SetTrigger(new Windows.ApplicationModel.Background.TimeTrigger(int, bool)); builder.Register()

Why is this needed:

Many apps should be activated once for a while (e.g. once per hour), to make something. I want to convert to Uno (and Android) app which checks air pollution and show notification about current status.

For which Platform:

  • iOS
  • Android
  • WebAssembly
  • WebAssembly renderers for Xamarin.Forms
  • Windows
  • Build tasks
  • Solution Templates

Anything else we need to know?

Contributor guide

Research direction
Study existing Uno background task implementations, understand the Windows.ApplicationModel.Background API spec, and implement BackgroundTaskBuilder, TimeTrigger, and Register methods. Check how other WinRT APIs are mapped cross platform.
