--- layout: default-layout title: Android Release Notes v11.x - Dynamsoft Barcode Reader description: This is the release notes page of Dynamsoft Barcode Reader Android SDK v11.x. keywords: release notes, android, version 11.x, needAutoGenerateSidebar: true needGenerateH3Content: false noTitleIndex: true --- # Release Notes for Android SDK - 11.x ## 11.6.2000 (08/14/2026) ### New - Added support for Micro PDF417-specific decoding mode. ### Fixed - Fixed several known crash issues. ## 11.6.1000 (07/30/2026) ### Highlights #### Multi-Threaded Barcode Decoding - **Get results sooner with parallel processing** - Barcode decoding now uses a breadth-first strategy that decomposes a single DBR Task into one Localization Work and one or more Decoding Works. This improves thread utilization and reduces the chance that a slow `DeblurMode` attempt blocks other faster decoding attempts, helping valid results come back sooner. #### DataMatrix Color Inversion Detection - **Handle normal and inverted DataMatrix more efficiently** - Added [`AutoDetectColorInversion`]({{ site.dcvb_parameters_reference }}barcode-format-specification/auto-detect-color-inversion.html) to automatically handle both normal and inverted DataMatrix barcodes. Instead of processing the whole image twice, the SDK applies dual-polarity handling only to localized DataMatrix regions, which makes processing faster in dual-polarity scenarios. #### Barcode Layout Analysis - **Decode dense grid barcodes more completely** - Added [`LayoutAnalyzer`]({{ site.dcvb_android_api }}utility/layout-analyzer.html) to organize barcode locations into logical line or matrix layouts and infer unrecognized barcode regions when gaps exist, enabling workflows such as fast first-pass decoding, missing-region inference, and targeted second-pass decoding on dense N*M barcode layouts. #### Cross-Version License Support - **Use a single license across SDK versions** - Full License 1.0 keys (starting with "f") that are non-perpetual are no longer version-checked, so the same key can be used across SDK versions without reactivation. ### New - Added [`AutoDetectColorInversion`]({{ site.dcvb_parameters_reference }}barcode-format-specification/auto-detect-color-inversion.html) parameter for `BarcodeFormatSpecification` to support automatic color-inversion detection for DataMatrix barcodes. - Added [`LayoutAnalyzer`]({{ site.dcvb_android_api }}utility/layout-analyzer.html) class with [`analyze()`]({{ site.dcvb_android_api }}utility/layout-analyzer.html#analyze) static method for quadrilateral layout analysis. - Added [`LayoutPattern`]({{ site.dcvb_android_api }}utility/enum-layout-pattern.html) enumeration with values `LP_UNKNOWN`, `LP_LINES`, and `LP_MATRIX`. - Added [`LayoutElementSource`]({{ site.dcvb_android_api }}utility/enum-layout-element-source.html) enumeration with values `LES_NONE`, `LES_INPUT`, and `LES_INFERRED`. - Added [`MeasureUnit`]({{ site.dcvb_android_api }}core/enum-measure-unit.html) enumeration with values `MU_PIXEL` and `MU_PERCENTAGE`. - Added [`LayoutAxis`]({{ site.dcvb_android_api }}utility/layout-axis.html), [`LayoutAnalysisParameter`]({{ site.dcvb_android_api }}utility/layout-analysis-parameter.html), [`LayoutElement`]({{ site.dcvb_android_api }}utility/layout-element.html), and [`LayoutAnalysisResult`]({{ site.dcvb_android_api }}utility/layout-analysis-result.html) for layout analysis configuration and results. - Added a new `GridBarcodeScanner` sample (with `sample_grid.png`) to demonstrate how to use [`LayoutAnalyzer`]({{ site.dcvb_android_api }}utility/layout-analyzer.html) for barcode grid layout detection and logical row/column mapping. ### Changed - [`MaxParallelTasks`]({{ site.dcvb_parameters_reference }}capture-vision-template/max-parallel-tasks.html) now controls the total number of Work-level threads in the CVR thread pool. For DBR tasks, each Localization Work and Decoding Work occupies one thread slot. DLR and DDN tasks continue to occupy one thread per task. - [`set_device_friendly_name()`]({{ site.dcvb_android_api }}license/license-manager.html#set_device_friendly_name) now enforces parameter constraints: maximum 64 characters, allowed characters are letters (a-z, A-Z), digits (0-9), hyphen (-), underscore (_), and period (.), and must start and end with a letter or digit. Returns [`EC_PARAMETER_VALUE_INVALID`]({{ site.dcvb_android_api }}core/enum-error-code.html) if constraints are not met. - Improved the default display behavior of corner adjustment points in `ImageEditorView`. Previously, users had to tap the view before the corner adjustment points became visible. ### Fixed - Fixed an issue in GS1-Databar AI `17` (YYMMDD) results where the month field could be missing a leading zero. ## 11.4.3000 (07/07/2026) ### Security Updates - Updated third-party libraries to incorporate the latest security fixes. ## 11.4.1300 (05/20/2026) ### Fixed - Fixed potential issues that could occur on devices running a kernel with a 16KB page size. - Fixed crash and hang issues that could occur in certain scenarios. ## 11.4.1200 (04/02/2026) ### Improved - Updated camera lifecycle management code to improve stability. ### Fixed - Fixed an issue where downloading deep learning models could fail. ## 11.4.1000 (02/05/2026) ### Highlights #### AI-Powered Barcode Detection and Decoding - **PDF417 Localization Model** – Introduces the `PDF417Localization` neural network model for improved detection of PDF417 barcodes, especially under challenging conditions. - **Code39/ITF Decoding Model** – Adds the `Code39ITFDecoder` model for enhanced decoding of Code 39 and ITF barcodes under blurred or low-resolution conditions. - **Deblur Models for 2D Barcodes** – Adds the `DataMatrixQRCodeDeblur` and `PDF417Deblur` models provide more effective recovery from motion and focus blur for DataMatrix, QR Code, and PDF417 barcodes. #### ECI (Extended Channel Interpretation) Support - **ECI Information Return** – Adds support for retrieving Extended Channel Interpretation (ECI) data from barcodes. The new [`ECISegment`]({{ site.dbr_android_api }}eci-segment.html) class, along with [`getECISegments`]({{ site.dbr_android_api }}barcode-result-item.html#getecisegments) method in [`BarcodeResultItem`]({{ site.dbr_android_api }}barcode-result-item.html) class, enable access to character encoding information embedded in barcodes. - **ECI-Based Text Interpretation** – Adds support for interpreting ECI segments during barcode decoding, improving compatibility with international character sets. #### Performance Improvements - **On-Demand Model Loading** – Implements lazy loading for AI models, reducing initialization time by loading models only when first needed. - **Smart Model Selection** – Models are now loaded based on configured barcode formats, minimizing memory usage by excluding unused models. - **Improved Confidence Scoring** – Enhances confidence score calculation for results from neural network models, providing more accurate quality indicators. - **DPM Barcode Optimization** – Improves recognition rate for Direct Part Marking (DPM) barcodes commonly used in industrial and manufacturing environments. ### New - Added [`BarcodeZoneWidthToHeightRatioRangeArray`]({{ site.dcvb_parameters_reference }}barcode-format-specification/barcode-zone-width-to-height-ratio-range-array.html) parameter for filtering barcodes based on aspect ratio constraints. - Added [`setResultCrossVerificationCriteria`]({{ site.dcv_android_api }}utility/multi-frame-result-cross-filter.html#setresultcrossverificationcriteria) and [`getResultCrossVerificationCriteria`]({{ site.dcv_android_api }}utility/multi-frame-result-cross-filter.html#getresultcrossverificationcriteria) methods to [`MultiFrameResultCrossFilter`]({{ site.dcv_android_api }}utility/multi-frame-result-cross-filter.html) for configurable multi-frame result verification. - Added a new resolution [`RESOLUTION_MAX`]({{ site.dce_android_api }}enum/resolution.html) for capturing photos at maximum resolution (3024*4032). - Added a new listener [`FocusListener`]({{ site.dce_android_api }}auxiliary-api/interface-focus-listener.html) for receiving callback when the camera focus is completed.
