# AppLinksUseCases

`class AppLinksUseCases` [(source)](https://github.com/mozilla-mobile/android-components/blob/master/components/feature/app-links/src/main/java/mozilla/components/feature/app/links/AppLinksUseCases.kt#L45)

These use cases allow for the detection of, and opening of links that other apps have registered
an [IntentFilter](#)s to open.

Care is taken to:

* resolve [intent//](intent//) links, including [S.browser_fallback_url](#)
* provide a fallback to the installed marketplace app (e.g. on Google Android, the Play Store).
* open HTTP(S) links with an external app.

Since browsers are able to open HTTPS pages, existing browser apps are excluded from the list of
apps that trigger a redirect to an external app.

### Parameters

`context` - Context the feature is associated with.

`launchInApp` - If {true} then launch app links in third party app(s). Default to false because
of security concerns.

`unguessableWebUrl` - URL is not likely to be opened by a native app but will fallback to a browser.

`alwaysDeniedSchemes` - List of schemes that will never be opened in a third-party app.
