v4.2.24

QuickCapture Android SDK v4.2.24

This release focuses on stability, performance, and memory optimizations, particularly for high–frame-rate capture scenarios and long-running sessions.

Fixes & Improvements

• 32-bit Architecture Crash Fix
  Resolved memory alignment issues in the JNI layer related to OpenCV submat usage, eliminating crashes on 32-bit devices.

• Improved ImageReader Buffer Management
  Optimized ImageReader processing with synchronous conversion and immediate buffer release, preventing maxImages buffer exhaustion and ensuring smooth high-FPS operation.

• Enhanced Glare Detection Performance
  Refactored glare detection using pre-allocated native memory and luminance-channel extraction, significantly reducing CPU usage.

• Optimized ConvertToBitmap Pipeline

  • Introduced a fast-path YUV → RGBA conversion for live processing
  • Improved padding handling to fix skewed or slanted images on specific hardware (e.g., Samsung devices)

• Native Memory Lifecycle Cleanup
  Added comprehensive native memory cleanup during onDestroy, preventing memory leaks during extended or repeated capture sessions.

• Critical Memory Leak Fix
  Removed the static Activity context reference from ImgHelper, resolving a major memory leak that retained destroyed activities.

New Features

• Low-Light Torch Support
  Added EnableTorchOnLowLight configuration option to automatically enable the torch in low-light conditions.

• Corner Detection Enhancements

  • Added correction logic for missing corner points
  • Improved padding support for better edge and boundary accuracy

UI & UX Improvements

• Fixed toast display issues on the review screen
• Added a magnifier to the cropping guide for more precise adjustments
• Improved ConvertToBitmap performance during live document detection

Additional Performance Improvements

• Multiple internal optimizations across capture, processing, and rendering paths for improved responsiveness, stability, and reduced CPU/memory overhead.
