Initialization

Before any audio submission, Biometrid's voice engine requires to be initialised. This allows the retrieval of previous sessions and the start of new ones.

Initialisation method

BiometridAuthVoice.getInstance().init(
    String id, //biometrid id 
    Enum SessionType, //ex: SessionType.Verify
    AuthVoiceCallback your_context
);

initVoice()	method
String id	id corresponding the biometric user
SessionType session	session to initialise
AuthVoiceCallback	Applicational context

Callback

@Override
    public void authVoiceInitCallback(boolean status, SessionType session, String prompt, @Nullable JSONObject json, @Nullable Errors errors) {
       if(!status && serrors != null) 
          Log.e("error", error.getMessage());
       else {
          Log.i("current session", session.getName());
          Log.i("active prompt", prompt);
       }
    }

authVoiceInitCallback	callback
boolean status	request status
SessionType session	active session
String prompt	prompt for next submission
JsonObject json	complete response from api
Errors errors	error object

Implementation example

public class ExampleActivity extends Activity 
        implements AuthVoiceCallback {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_example);

       BiometridAuthVoice.getInstance().init(
           "user_id", 
           SessionType.ENROLL, 
           this
       );
    }

   @Override
    public void authVoiceInitCallback(boolean status, SessionType session, String prompt, @Nullable JSONObject json, @Nullable Errors errors) {
        if(errors =! null){
            //handle erros
            switch(errors){
                case INVALID_CREDENTIALS:
                     Log.e("error", errors.getMessage());
                break;
                ...
            }
        }
        else {
            /*This variable contains the next expected 
            set of numbers for the corresponding session */
            Log.i("prompt", prompt);
        }
    }

    ...
