public class TrustedWebUtils
extends Object

java.lang.Object
↳	androidx.browser.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 CustomTabsCallback.onRelationshipValidationResult(int, Uri, boolean, Bundle) for sending details of the verification results.

Constants

EXTRA_LAUNCH_AS_TRUSTED_WEB_ACTIVITY

public static final String EXTRA_LAUNCH_AS_TRUSTED_WEB_ACTIVITY

Boolean extra that triggers a CustomTabsIntent launch to be in a fullscreen UI with no browser controls.

Constant Value: "android.support.customtabs.extra.LAUNCH_AS_TRUSTED_WEB_ACTIVITY"

Public methods

launchAsTrustedWebActivity

public static void launchAsTrustedWebActivity (Context context, 
                CustomTabsIntent customTabsIntent, 
                Uri uri)

This method is deprecated.
Use TrustedWebActivityIntentBuilder instead.

Launch the given CustomTabsIntent as a Trusted Web Activity. The given CustomTabsIntent should have a valid CustomTabsSession associated with it during construction. Once the Trusted Web Activity is launched, browser side implementations may have their own fallback behavior (e.g. Showing the page in a custom tab UI with toolbar) based on qualifications listed above or more.

Parameters
`context`	`Context`: `Context` to use while launching the `CustomTabsIntent`.
`customTabsIntent`	`CustomTabsIntent`: The `CustomTabsIntent` to use for launching the Trusted Web Activity. Note that all customizations in the given associated with browser toolbar controls will be ignored.
`uri`	`Uri`: The web page to launch as Trusted Web Activity.

splashScreensAreSupported

public static boolean splashScreensAreSupported (Context context, 
                String packageName, 
                String version)

Returns whether the splash screens feature is supported by the given package. Note: you can call this method prior to connecting to a CustomTabsService. This way, if true is returned, the splash screen can be shown as soon as possible.

Parameters
`context`	`Context`: `Context` to use.
`packageName`	`String`: The package name of the Custom Tabs provider to check.
`version`	`String`: The splash screen version/feature you are testing for support. Use a value from `SplashScreenVersion`.

Returns
`boolean`	Whether the specified Custom Tabs provider supports the specified splash screen feature/version.

transferSplashImage

public static boolean transferSplashImage (Context context, 
                File file, 
                String fileProviderAuthority, 
                String packageName, 
                CustomTabsSession session)

Transfers the splash image to a Custom Tabs provider. The reading and decoding of the image happens synchronously, so it's recommended to call this method on a worker thread. This method should be called prior to launching the Activity. Pass additional parameters, such as background color, using TrustedWebActivityIntentBuilder.setSplashScreenParams(Bundle).

Parameters
`context`	`Context`: `Context` to use.
`file`	`File`: `File` with the image.
`fileProviderAuthority`	`String`: authority of `FileProvider` used to generate an URI for the file.
`packageName`	`String`: Package name of Custom Tabs provider.
`session`	`CustomTabsSession`: `CustomTabsSession` established with the Custom Tabs provider.

Returns
`boolean`	True if the image was received and processed successfully.
