AuthTabIntent

public class AuthTabIntent

Class holding an Intent and other data necessary to start an Auth Tab Activity.

Create an instance of this class using the Builder and then call launch to present the auth page to the user.

Upon completion of the auth flow, the webpage should redirect to a URL with the custom scheme or an HTTPS URL with the host and path provided to the launch method.

Before starting the auth flow, you should create an ActivityResultLauncher using registerActivityResultLauncher. This launcher should be created unconditionally before every fragment or activity creation. The ActivityResultCallback provided to the launcher will be called with the result of the authentication flow, indicating success or failure.

If using an HTTPS redirect URL, you need to establish that your app and the redirect URL are owned by the same organization using Digital Asset Links. If the verification fails, the Auth Tab will return an AuthResult with the result code RESULT_VERIFICATION_FAILED.

Code sample: 

// In your activity
private final ActivityResultLauncher<Intent> mLauncher =
            AuthTabIntent.registerActivityResultLauncher(this, this::handleAuthResult);

private void handleAuthResult(AuthTabIntent.AuthResult result) {
    // Check the result code
    boolean success = result.resultCode == AuthTabIntent.RESULT_OK;
    String message =
            getResources()
                    .getString(success ? R.string.auth_tab_success : R.string.auth_tab_failure);
    // Retrieve the result Uri
    message += " uri: " + result.resultUri;
    Toast.makeText(this, message, Toast.LENGTH_LONG).show();
}

...

private void launchAuthTab() {
    AuthTabIntent authTabIntent = new AuthTabIntent.Builder().build();
    authTabIntent.launch(mLauncher, Uri.parse("https://www.example.com/auth"), "myscheme");
}

...

Note: The constants below are public for the browser implementation's benefit. You are strongly encouraged to use AuthTabIntent.Builder.
