Even if your app automatically updates its content on a regular basis, you
|
||
|
|
can allow users to request manual updates as well. For example, a weather
|
||
|
|
forecasting app can allow users get the latest forecasts on demand. To
|
||
|
|
provide a standard user experience for requesting updates, the Android
|
||
|
|
platform includes the swipe-to-refresh design pattern, which allows users
|
||
|
|
to trigger an update with a vertical swipe.
