Initialization

In order to use any of the SDK functionalities, the application needs to initialise it first, using the credentials provided during the enrolment on our platform.

Method

BiometridAuth.getInstance().init(
       POLYGON_API_KEY
       POLYGON_API_SECRET,
       POLYGON_API_URL,
       Context
);

init()	method
String key	String corresponding to the provided access key
String secret	String corresponding to the provided access secret
String url	String corresponding to the provided access url
AuthInitialization context	Applicational context

Implementation example

This action can be performed at any time during, but we recommend the following implementation:

public class Example extends Application implements AuthInitializationCallback {

    private final static String BIOMETRID_AUTH_SERVER_URL = "";
    private final static String BIOMETRID_AUTH_CREDENTIAL_KEY = "";
    private final static String BIOMETRID_AUTH_CREDENTIAL_SECRET = "";

    @Override
    public void onCreate() {
        super.onCreate();
        BiometridLibrary.getInstance().init(
                BIOMETRID_AUTH_CREDENTIAL_KEY,
                BIOMETRID_AUTH_CREDENTIAL_SECRET,
                BIOMETRID_AUTH_SERVER_URL,
                this
        );
    }

    @Override
    public void authInitCallback(boolean status, String biometrid_id, @Nullable Errors errors) {
        // callback from init
    }
}

Note:

If the device used already has a record in BiometridAuth, their user id will be returned at init. A BiometridAuth user is only created once and is associated with the device where it was created.

Reinstalling the app won 't remove the user. There is a specific method for user deletion.
