Stay organized with collections
Save and categorize content based on your preferences.
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.
