Use when

  • When effective usage of screen space is required.
  • To provide rich experience to the user.

Benefits

  • Different variants of application not required for different screens.
  • Some applications like browser can be used much better in landscape mode.
  • Less effort required to support the application on a new device.

Design Tips

  • Built in system components already supports scalability.
  • Custom components should be designed and tested properly for scalability.
  • Orientation change can be initiated through a hardware event and also through the application.
  • On change of orientation, the application should continue normally.
  • In case a particular screen is not supported, proper error dialog should be displayed to the user.
  • Application data like text, images should be rendered properly for different screens and should be easily readable by the user.
