Release Notes for Android SDK - 9.x
9.6.40 (03/21/2024)
Improved
- Updated the security of the
DynamsoftBarcodeReader
library and other corresponding dependent libraries. - Improved the multi-thread processing logic of concurrent instance licenses.
- Improved the barcode decoding performance:
- Improved the accuracy when decoding OneD & PDF417 barcodes.
- Improved the readability of dense DataMatrix codes.
Changed
- Added a new error code
DM_LICENSE_CACHE_USED
, which is returned when failing to connect to the license server but a valid license cache is available. Error codesDM_FAILED_TO_REACH_DLS
andDM_LICENSE_SYNC_FAILED
are no longer returned in this scenario.
Fixed
- Fixed crash bugs in the barcode decoding algorithm.
- Fixed a bug where the location of the barcode result(s) might be incorrect.
9.6.20 (03/16/2023)
Fixed
- Fixed a bug where license authorization may fail when the main license server is not available.
- Other small fixes and tweaks.
9.6.11 (01/16/2023)
Fixed
- Fixed a bug that the barcode decoding thread might not restart when
startScanning
is triggered shortly afterstopScanning
.
9.6.10 (01/10/2023)
Fixed
- Fixed a bug that some OneD barcodes without start & stop characters are not decoded when parameter
RequireStartStopChars
is set to 0. - Fixed a crash bug by adding protection in algorithm.
Improved
- Improved the performance of Direct Part Marking (DPM) barcode decoding.
- Improved the performance of GS1 Databar barcode decoding.
9.6.0 (12/13/2022)
Version Highlights
- Image orientation handling is supported by a new feature. With the new feature, you can:
- Get a TranformationMatrix along with the barcode location result.
- Implement coordinates transformation on the barcode location result with the TransformationMatrix.
- DotCode decoding is improved by optimizing the localization of DotCodes that are close to one another.
- EAN8 barcode decoding is improved by honing the accuracy of localization algorithms.
- QR code localizing is improved by reducing the mis-assemble rate of the finder patterns when using the localization mode LM_CONNECTED_BLOCK or LM_SCAN_DIRECTLY, which are designed for speed. The mis-assembling only occurs when there exist dense QR codes on the same image.
- Mirrored rectangular DataMatrix barcode is supported by implementing
MirrorMode
when localizing the barcodes.
- Deformed barcode decoding is improved by extending the supported modes and mode arguments of
DeformationResistingModes
.
