Initialization

This section contains the necessary methods to init Biometrid Standard.

In order to use any of the SDK functionalities, the application needs to initialize it first, using the credentials provided during the enrollment on our platform (see prerequisites section above).

BiometridFull.INSTANCE.initialize(
                BIOMETRID_API_SERVER_URL,
                BIOMETRID_APP,
                BIOMETRID_CREDENTIAL,
                BIOMETRID_APP_URL,
                customHeaders,
                this);

Parameter	Description
String BIOMETRID_APP	Application key provided
String BIOMETRID_CREDENTIAL	Credential provided
String BIOMETRID_SERVER_URL	URL credential provided
String BIOMETRID_APP_URL	App URL provided
HashMap<String, String> HashMap	Custom Headers
InitializationCallback callback	Result callback

The method above requires the callback to be linked with an activity to obtain the application Context, however this method is not required. When implementing the InitializationCallback outside of an activity, prefer using the following method:

BiometridFull.INSTANCE.initialize(
                BIOMETRID_API_SERVER_URL,
                BIOMETRID_APP,
                BIOMETRID_CREDENTIAL,
                BIOMETRID_APP_URL,
                customHeaders,
                this,
                context);

Parameter	Description
String BIOMETRID_APP	Application key provided
String BIOMETRID_CREDENTIAL	Credential provided
String BIOMETRID_SERVER_URL	URL credential provided
String BIOMETRID_APP_URL	App URL provided
HashMap<String, String> HashMap	Custom Headers
InitializationCallback callback	Result callback
Context context	Context of your app

Implementation example

class ExampleActivity extends AppCompatActivity implements InitializationCallback, InterfaceCallback {
    String TAG = getClass().getSimpleName();
    String BIOMETRID_API_SERVER_URL = "your server URL";
    String BIOMETRID_APP = "your app";
    String BIOMETRID_CREDENTIAL = "your credential";
    String BIOMETRID_APP_URL = "app URL";
    
    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        
        try{
            BiometridFull.INSTANCE.initialize(
                BIOMETRID_API_SERVER_URL ,
                BIOMETRID_APP,
                BIOMETRID_CREDENTIAL,
                BIOMETRID_APP_URL,
                new HashMap<>(),    
                this);
        } catch (UnableToConnectException e) {
            e.printStackTrace();
        }
    }
    
    @Override
    public void initializationCallback(boolean status, @Nullable Errors error) {
        Log.d(TAG, "initializationCallback-> status: " + status);
        if(error != null) Log.e(TAG, "initializationCallback-> error: " + error.name());
    }
    
    @Override
    public void processCreated(String processId) {
        Log.d(TAG, "Process created -> id: " + processId);
    }

    @Override
    public void processFinished() {
        Log.d(TAG, "Process finished");
    }

    @Override
    public void interfaceStarted() {
        Log.d(TAG, "Interface started");
    }

    @Override
    public void interfaceClosed() {
        Log.d(TAG, "Interface closed");
    }
}
