Application Lifetime

Apps can be in 1 of 3 states

Not Running Running Suspended

Application receive events when transitioning between states

Except: Suspended->NotRunning

  • Version adaptive
  • App runs on a base OS version but can use up-level APIs
  • Device family adaptive
  • App uses device family-specific APIs when running on such a device
  • Form factor adaptive aka responsive layout
  • App provides user-interface tailored to one or more specific form factors

Multiple Adaptive Dimensions

Windows.Devices Namespace

Includes APIs to direct access buses

slide-26
SLIDE 26

Accessing Buses Directly

  • Windows.Devices.I2c
  • Contains types that you can use to communicate with peripheral devices

connected through a inter-integrated circuit (I²C) bus from an application.

  • Windows.Devices.Gpio
  • Contains types for using general-purpose I/O (GPIO) pins in user mode.
