   }
   

V3.6.2（2025.6.03）

New Features

• Optimize resolution selection to ensure a reasonable device distance during liveness detection on the vast majority of smartphones.

Migration Guides

1. Change the dependency version number to3.6.2:

   xxxxxxxxxx
   dependencies {
     ...
     implementation 'ai.advance.mobile-sdk.android:liveness-detection:3.6.2'

Migration Guides

1. Change the dependency version number to3.6.1:

   xxxxxxxxxx
   dependencies {
     ...
     implementation 'ai.advance.mobile-sdk.android:liveness-detection:3.6.1'

• Optimize billing-related rules.

Migration Guides

1. Change the dependency version number to3.6.0:

   xxxxxxxxxx
   dependencies {
     ...
     implementation 'ai.advance.mobile-sdk.android:liveness-detection:3.6.0'
   }
   

2. Set SignatureId (optional feature; if this id is not set or is set to empty, the livenessId method will remain unchanged)

   In the following known situations, the livenessId generated by AAI may not be transmitted to your server, resulting in the loss of these livenessId outcomes. To address this issue, your backend can call the AAI interface to generate a SignatureId and pass it to the SDK. The SignatureId can be used to obtain the liveness score and has equivalent functionality to the livenessId.

   xxxxxxxxxx
   1. During the upload of the liveness image, the user clicks the back button and leaves the page.
   2. After successful liveness, the app encounters an unexpected issue (such as a network error or app crash) and fails to transmit the livenessId to the server.
   

   Please note: SignatureId can be empty but must not be reused

   xxxxxxxxxx
   GuardianLivenessDetectionSDK.setSignatureId(signatureId);

   }
   

V3.3.0（2024.5.31）

New Features

1. Fixed warnings from some detection platforms on VirusTotal.

   The Liveness SDK is falsely reported as containing viruses by some platforms on VirusTotal . If your app promotion relies on VirusTotal 's detection results, it is recommended that you upgrade to this version

   • If you have integrated certain versions due to SDK virus issues, and you have modified the imported SDK class path to adapt to these versions, when integrating 3.3.0, you can revert these changes and the SDK class path will be fixed toaai.liveness.**
   • If you have previously integrated a specific version that changed LivenessViewthe name of , when integrating 3.3.0, please revert the name of this class toLivenessView
   • 3.3.0 is a standard general version. Although we have completely modified the names of internal classes and encryption algorithms, we still cannot completely avoid being marked in the future. Starting from version 3.3.0, we support packaging exclusive versions for you. The internal classes of exclusive versions will not be repeated with other customers, which can avoid being marked to a greater extent. In addition, there is no other integration difference between the exclusive version and the standard version except for the difference in version number.

2. The performance of the livenesss collection process has been optimized, and the user pass rate has been significantly improved.

3. UI interaction adjustments

   Currently, the ellipses in the entire 3D liveness detection process are the same color. We have adjusted the status during detection, maintaining green in the stationary state and gray in other states.

   If you want to maintain the previous interaction effect, you can call the following methods to set the ellipse color in these two states:

   xxxxxxxxxx
   mLivenessView.setOvalColor(Color.parseColor("#5BC413"));
   mLivenessView.setOvalNormalColor(Color.parseColor("#5BC413"));
   

4. Supports capturing an audit graph at a specified time

   xxxxxxxxxx
   // Added setRelativeSecondsCaptureAfterCameraLaunched(2.3f) configuration to the original audit image configuration. You can specify the screenshot time relative to the camera opening, in seconds. If this setting is not called, the image will not be captured.
   // The newly added image exists in the original image array
   GuardianLivenessDetectionSDK.setAuditImageConfig(new AuditImageConfig
           .AuditImageConfigBuilder()
           .setEnableCollectSwitch(true)
           .setImageCaptureInterval(400)
           .setImageMaxNumber(10)
           .setImageWidth(400)
           .setImageQuality(30)
           .setRelativeSecondsCaptureAfterCameraLaunched(2.3f)
           .build());
   

5. Added uploading timestamps for near and far view images

   Starting from version 3.3.0, when you call the backend score interface, farImageTime and nearImageTime will be returned additionally, representing the timestamp for the capture of the far and near images respectively.

Migration Guides

   xxxxxxxxxx
   dependencies {
     ...
     // version log:https://public-n3.advai.net/repository/maven-releases/ai/advance/mobile-sdk/android/liveness-detection/maven-metadata.xml

   When this feature is enabled, we will capture multiple images during the user's movement based on your configuration.

   xxxxxxxxxx
   GuardianLivenessDetectionSDK.setAuditImageConfig(new AuditImageConfig
                   .AuditImageConfigBuilder()
                   .setEnableCollectSwitch(true)// The function open switch,default value is false

   public class LivenessImageData {
     public final String base64Image;// Base64 format image
     public final long timestamp;// Timestamp of image capture.
   }
   

3. Video recording feature.

   By enabling this feature, the SDK will activate video recording. After the completion of the liveness process, you can retrieve the video file using SDK methods. The video file format is .mp4. Please note that this video can only be obtained through the SDK and cannot be obtained from the backend. After using the video, it is up to you to decide whether to delete the local file.

   xxxxxxxxxx
   GuardianLivenessDetectionSDK.setRecordVideoSwitch(true);
   GuardianLivenessDetectionSDK.setMaxRecordVideoSeconds(60);// Maximum recording duration, in seconds, valid range [2,60], default is 60 seconds.
