​
PassiveFaceLivenessCustomizationAndroid constructor
String styleResIdName
Name of the style resource that defines the colors of the SDK. For example, if you want to change the SDK colors, create a style in ROOT_PROJECT/android/app/src/main/res/values/styles.xml with the name R.style.my_custom_style following the template and parameterize "my_custom_style".
String layoutResIdName
Name of the resource layout that will replace the default SDK layout. For example, if you want to change the SDK layout, create a layout in ROOT_PROJECT/android/app/src/main/res/layout/my_custom_layout.xml following the template and parameterize "my_custom_layout".
String greenMaskResIdName
Name of the drawable resource to replace the default green mask. If you are going to use this parameter, use a mask with the same cutting area, it is important for the detection algorithm. For example, save the mask image in ROOT_PROJECT/android/app/src/main/res/drawable/my_custom_green_mask.png and parameterize "my_custom_green_mask".
String redMaskResIdName
Name of the drawable resource to replace the default red mask. If you are going to use this parameter, use a mask with the same cutting area, it is important for the detection algorithm. For example, save the mask image in ROOT_PROJECT/android/app/src/main/res/drawable/my_custom_red_mask.png and parameterize "my_custom_red_mask".
String whiteMaskResIdName
Name of the drawable resource to replace the default white mask. If you are going to use this parameter, use a mask with the same cutting area, it is important for the detection algorithm. For example, save the mask image in ROOT_PROJECT/android/app/src/main/res/drawable/my_custom_white_mask.png and parameterize "my_custom_white_mask".
​
CaptureSettings constructor
int beforePictureMillis
Duration in milliseconds between the first face detection and the actual photo capture
int afterPictureMillis
Duration in milliseconds between capturing the photo and sending it to the server to keep the face and sensors valid
​
SensorSettingsAndroid constructor
SensorStabilitySettingsAndroid sensorStabilitySettings
Orientation sensor settings to be applied in all SDK steps
​
SensorStabilitySettingsAndroid constructor
String messageResourceIdName
Name of the string resource to be shown when the phone is not stable. The default message is "Keep cell phone still". For example, if you want to show the String "Test", create a String in ROOT_PROJECT/android/app/src/main/res/values/strings.xml with name R.string.my_custom_stability_string and value "Test" and parametrize "my_custom_stability_string".
int stabilityStabledMillis
How many milliseconds the cell phone must stay at the correct threshold to be considered stable. The default is 2000 ms
double stabilityThreshold
Lower threshold between stable/unstable, in m/s² variation between the last two sensor collections. The default is 0.5 m/s².
​

Collecting the result

The DocumentDetector return object will have the result attribute that contains a string SUCCESS, FAILURE or CLOSED. The return will default to PassiveFaceLivenessSuccess, PassiveFaceLivenessFailure and PassiveFaceLivenessClosed, respectively, for each of the cases.
​

PassiveFaceLivenessSuccess

Field
​
String imagePath
Full address of the image on the device
​
String imageUrl
URL of the image temporarily stored on CAF servers
​
String signedResponse
Signed response from the CAF server which confirmed that the captured selfie has a real face (not a photo or video). Use this parameter if you want an extra layer of security by checking that the signature of the response is not broken, caused by an intercepted request. If it is broken, there is a strong indication of request interception
​
String trackingId
Identifier of this execution on our servers. If possible, save this field and send it along to our API. This will give us more data about how the user behaved during the execution
Will be null if the user sets useAnalytics = false or the analytics calls do not work
​

PassiveFaceLivenessFailure

Field
String message
Friendly message explaining why the SDK failed
String type
Fault type that shut down the SDK
The existing fault types are:
  • InvalidTokenReason: when the token entered is invalid. It should not occur in a production environment;
  • PermissionReason: when some mandatory permission was not granted by the user. It will only happen in a production environment if your app does not ask your user or the user manually disables it before starting;
  • NetworkReason: server connection failure. Will occur in production if the user's device is without internet;
  • ServerReason: failure in some request with our servers. It will occur in production only in case of our failure;
  • SecurityReason: when the device is not safe to run the SDK. If this failure occurs, let us know;
  • StorageReason: when the device does not have enough space to capture some photo. This can happen in production;
  • LibraryReason: when some internal failure made it impossible to run the SDK. It can occur due to configuration errors in the project, it should not occur in production;

PassiveFaceLivenessClosed

Empty object indicating closure of the capture screen by the user.
