TrustedWebUtils

public class TrustedWebUtils
extends Object

java.lang.Object
   ↳ android.support.customtabs.TrustedWebUtils

Class for utilities and convenience calls for opening a qualifying web page as a Trusted Web Activity. Trusted Web Activity is a fullscreen UI with no visible browser controls that hosts web pages meeting certain criteria. The full list of qualifications is at the implementing browser's discretion, but minimum recommended set is for the web page :

  • To have declared delegate_permission/common.handle_all_urls relationship with the launching client application ensuring 1:1 trust between the Android native and web components. See https://developers.google.com/digital-asset-links/ for details.
  • To work as a reliable, fast and engaging standalone component within the launching app's flow.
  • To be accessible and operable even when offline.
Fallback behaviors may also differ with implementation. Possibilities are launching the page in a custom tab, or showing it in browser UI. Browsers are encouraged to use onRelationshipValidationResult(int, Uri, boolean, Bundle) for sending details of the verification results.
