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 codes DM_FAILED_TO_REACH_DLS and DM_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 after stopScanning.

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.

Changelog

New

• Added a new method setLogConfig so that user can get log information of the algorithm. Enumeration EnumLogMode is added so that users can set whether to save the log information.
• Enabled decoding methods decodeFile, decodeFileinMemory and decodeBase64String to read EXIF data of the given image so that the library can obtain the orientation information when processing image file.
• Override method decodeBuffer. You can input an ImageData object as the barcode decoding parameter. The library can obtain the orientation information from the ImageData object.
• Added a new property transformationMatrix to class LocalizationResult so that the library can output a transformation matrix for users to transform the coordinates of the barcode result.
• Added a new method setDuplicateForgetTime to filter out all duplicate barcode results for a period of time when processing video streaming.
• Added new properties hasLeftRowIndicator and hasRightRowIndicator to class PDF417Details to return whether the left or right row indicator of the PDF417 barcode is detected.
• Added a new member BF2_ALL to enumeration BarcodeFormatIds_2.
• Extended the features of DeformationResistingModes:
  • Extended the valid mode arguments of DRM_BROAD_WARP, DRM_LOCAL_REFERENCE and DRM_DEWRINKLE with two new arguments: GrayscaleEnhancementMode and BinarizationMode.
  • Support mode DRM_AUTO.

Improved

• Improved the accuracy when processing multiple QR codes.
• Improved the processing speed by excluding incorrectly located barcode zones before decoding.
• Improved the creation, destruction, and acquisition logic of concurrent instances.
• Improved the scan count of duplicate barcodes when the Charge Way is per scan.
• Improved the accuracy of EAN8 localization result(s).
• Improved the localization of mirrored DataMatrix barcode by implementing MirrorMode.

Fixed

• Fixed a bug that DotCodes might not be decoded when they are densely arranged.
• Fixed a crash bug when trying to output a template which includes customized value for parameterd BarcodeTextRegEexPattern.
• Fixed a bug that might cause memory churn when the instance/thread was created frequently.

Removed

• Removed destroy from class BarcodeReader.

9.4.0 (11/04/2022)

Version Highlights

• DotCode decoding has been improved by optimizing the localization and decoding algorithm.
• Stacked, skewed or perspective distorted OneD barcode decoding has been improved.

Changelog

New

• Added an argument IsOneDStacked to LM_SCAN_DIRECTLY to process stacked OneD barcodes.
• Added a parameter PatchCodeSearchingMargins to specify the searching area of PatchCode.
• Added the supported data format of FormatSpecification.PartitionModes to enhance the readability of the parameters. Users can use a list of enumeration names to specify the PartitionModes.

Improved

• Improved the localization mode LM_LINES to better support skewed and perspective OneD barcodes.
• Enhanced tamper resistance of the license keys so that any change to the license string makes it invalid.

Deprecated

• Deprecated the attribute barcodeFormatString_2 of TextResult, ExtendedResult and LocalizationResult. All the barcode format strings will be returned by the attribute barcodeFormatString.

9.2.10 (06/28/2022)

Version Highlights

• Barcode boundary-seeking algorithm is refactored to improve stability.
• Pharmacode decoding is optimized to improve accuracy.
• The function of device-alias is added to allow users to give each device a readable name. For end-users and administrators, this makes it more friendly to distinguish between devices about license usage statistics.

Changelog

New

• Added a new method setDeviceFriendlyName to set a human-readable name that identifies the device.
• Added a new interface ImageSource. It act as an adapter that transfer image data from external resources to the format that can be recognized by the Barcode Reader. The following APIs are available for users to reduce the code complexity when working with ImageSource:
  • setImageSource: Set ImageSource as the source of image data.
  • startScanning: Start obaining image from the ImageSource continuously.
  • stopScanning: Stop obtaining image from the ImageSource.
  • TextResultListener: The protocol that includes a callback method for users to receive decoded barcode results when decoding from the ImageSource.
