Liveness Detection SDK Release Note Android v4.2.1 (2026.06.26)

  • Crash Fix: Fix crash during camera relayout.

    • Detailed Description: After selecting the camera resolution and opening the camera, a repositioning process (relayout) is triggered. Under rare conditions, this process could cause a NullPointerException (NPE).
    • Note: We have captured only a single instance of this crash in production environments.
       
  • New Feature: Android 16 Adaptation.

    • Detailed Description: Fully adapted the SDK for Android 16 compatibility, incorporating the latest system-level behavior changes, including:
      • Enforced Edge-to-Edge: Full adaptation to Android 16's enforced edge-to-edge layout, ensuring seamless rendering behind system bars.
      • Predictive Back Gesture: Fully adapted to the updated back button and back gesture navigation mechanisms.
      • Orientation Override (API 36 & Width > 600dp & target SDK 36): Adapted to the behavior where portrait-only constraints are overridden by the system when running on Android 16 (API 36) with a screen width greater than 600dp (e.g., tablets or foldables).
         
  • New Feature: Landscape Mode Support for Liveness Detection.

    • Detailed Description: Prior to Android SDK version 4.2.1, only portrait mode was supported, and liveness detection could not be completed normally in landscape orientation. Version 4.2.1 introduces native support for landscape mode.
    • Implementation Note: Our default UI SDK is still configured to force portrait mode by default, as it offers a superior user experience. However, clients can now customize this setting to allow the liveness detection interface to rotate dynamically with the device orientation.
