    • Barcode reader now reads at a fixed rate of every third frame.
    • Fixed camera error on some devices caused by using an autofocus region near/equal to the size of the full camera preview FOV.
    • Removed ACCESS_NETWORK_STATE permission from the SDK manifest.
  • Camera
    • Deprecated CameraHelper.setFocusRegion(). Metering regions near/equal to the size of the full preview FOV can cause unpredictable behavior on some handsets, depending on the OEM. Developers are encouraged to use CameraHelper.setFocusPoint instead.

DM SDK 3.5 - 4/22

Changes:

  • SDK
    • Now supports detection and resolving of Package ID data for recycling applications. This feature may be enabled with the existing EnablePlasticsReading reader option for applications that need to support recycling scenarios.
    • Deprecated ImageReader.setImageDetectionRegion(RectF) and VideoCaptureReader.setImageDetectionRegion(RectF) methods. Those methods may not behave correctly if used with a display rotation beyond the device's natural orientation or if frames are being delivered from a source other than CameraHelper. Apps that need to restrict the detection area should use the new setImageDetectionRegion(DetectionRegion) method.
    • DMSDetectorView changes for screen overlays.
      • Added new API setOverlayType(). The options available are Crosshairs, Detect Region or None, with Crosshairs being the default.
      • The setImageDetectionRegion() method now sets the camera focus region to match the detection region.
      • Calling setImageDetectionRegion() will update the location of the screen overlay if one is enabled. The Crosshairs will be moved to the center of the detection region. The Detect Region will be sized to match the region bounds.
      • Deprecated setShowAimingView() and showDetectRegion(). The new setOverlayType() API should be used instead.
      • Deprecated setAimingView().
    • The DMStockTake app now includes a demonstration of image detection regions. A button on the toolbar cycles through several region options and a new RegionView class in the app highlights the current region.
    • Updated the AR Integration Guide based on latest version of ARCore (v1.30). The previous version of this guide was based on Google's Sceneform library, which is no longer maintained by Google. Note that the Sceneform-based sample app that accompanied this guide, DMSArDemo, was removed in DM SDK 3.3.
  • Camera
    • Improved support for device rotation.
    • Added support for setting the focus to either a point on the screen or a region. Note that these APIs are only functional on devices that support Camera2 Limited or higher.
    • Fixed a bug that could cause a reconfigure cycle when starting the camera. This fix improves camera startup time by 30-250 ms depending on the device.
    • Fixed a bug that could cause camera disconnect errors when switching views.
    • Improved support for multiple camera views.
      • Added setCameraSurfaceView() method to CameraHelper.Builder. Apps that need multiple camera views should use this to direct camera data to the appropriate CameraHelper instance. No action is required for apps based on DMSDetectorView, as it uses this API internally.
    • Deprecated CameraHelper.startPreview() and CameraHelper.stopPreview() methods.

DM SDK 3.4.2 - 9/21

Changes:

  • SDK
    • Added feature to distinguish between Code 128 and GS1-128 symbols. When reading a GS1-128 barcode the Code_128 representation value will begin with a FNC1 character. GS1-128 data is also accessible as GS1 AIs using the GS1_List and GS1_Formatted_List representations as well as the Payload class getGS1Data() method.
    • Fixed a crash that could occur when reading a QR Code containing a malformed URL.

DM SDK 3.4.1 - 8/21

Changes:

  • SDK
    • Fixed a rare crash on audio shutdown.

DM SDK 3.3 - 3/21

Changes:

  • SDK
    • Reduced size of SDK native binaries. Applications built with the SDK will be 2 MB smaller.
    • Added the ability to set minimum ITF Variable code length. By default 10 digits is the minimum ITF Variable code read. The option allows a minimum code length down to 8 digits.
    • Added getResolution() method to DMSDetectorView which returns the configured camera resolution for the current session.
    • Fixed bug in DMSDetectorView that prevented detect region overlay from drawing properly after the detection region was changed.
    • Fixed bug that could cause the wrong 1D barcode type to be reported when multiple barcodes of different types were detected in the same frame.
    • Fixed a crash that could occur on the Samsung Tab A7.
    • Fixed an issue that could cause a FileNotFoundException on first launch.

Changes:

  • SDK
    • DM SDK 3.0 is a major release and contains a number of breaking changes. Refer to the Porting Guide for more detail on how to migrate a project.
    • An API key is required to use the SDK. A key can be obtained from the Digimarc Barcode Manager portal, for existing customers and on a trial basis for SDK evaluation.
    • The minimum supported Android version is 4.1 (SDK 16). Android Studio 3.0+ is required.
    • API changes
      • Abstract methods in many SDK objects (readers, camera, resolver) have been replaced by listener interfaces. Some listeners are optional and may not be needed depending on the use case.
      • SDK objects are now constructed and initialized using a Builder pattern.
      • Multiple decode results per symbology can now be returned for a frame. The ReaderResult class wraps these and provides access to all read data as well as exposing which decodes were new for the most recent frame.
      • The Resolver now gets its configuration information, including username, password and resolver URL from the API key.
      • Payload
        • Representations may now be returned in more relevant types than String. See the Representation documentation for information on the return type for each representation.
        • GS1 AI data is now exposed through the Payload class method getGS1Data().
        • Several Payload helper classes have been removed. The data exposed by them is all available through either representations or the GS1 data method.
  • Camera
    • The Camera library has been incorporated into DM SDK itself. Import paths within application code and layouts will need to be changed.

    • Fixed a bug in the scheduler that resulted in a rare crash behavior.
    • Fixed a small bug in DetectorViewDemo that caused some history records to not have camera thumbnail images.
  • CameraHelper
    • Improved camera view scaling. When the camera view is limited or scaled within an application's UI the camera surface behind it will be scaled to fill the visible view fully while maintaining the capture aspect ratio. The surface will be centered within the visible area, meaning that camera's auto focus area matches the user's view.
    • NEW! Added method CameraHelper.getRectForVisibleSurface() which returns a region for the visible area of the camera view within the overall camera image. The area retrieved from this method can be passed to the setImageDetectionRegion() method of the ImageReader and VideoCaptureReader classes so that 1D barcode detection does not occur outside of the visible camera area.

DM SDK 2.8 - 3/18

  • Performance improvements and bug fixes.

DM SDK 2.0 - 8/16

Digimarc Mobile SDK 2.0 is a major release and contains some significant changes and improvements over DM SDK 1.x. It should be noted that these changes are primarily found in the lower level components of the SDK rather than the UI components (DIS - previously referred to as the Drop-In SDK). Applications that use the UI component -- DMSDetectorView -- will need few changes to get up and running with the new SDK.

Porting guides can be found under the Docs folder for bringing your app from DM SDK 1.x to the new SDK. There are separate documents for applications using the DIS UI components and those using the lower level SDK components.

Note that use of this SDK to read traditional barcodes has a license cost associated with it. Please refer to https://www.digimarc.com/application/mobilesdk for more information.


Changes & New Features
  • Image readers, audio readers and the Digimarc Resolver are now separate components. They can be created, initialized and used as needed and are not part of a larger session concept.
  • Performance scaling is now standard behavior, and separate configuration files are no longer part of the SDK. The image and audio readers will monitor how much work the system is doing and automatically adapt their performance to keep from overstressing the device. This behavior can be disabled if needed, but in most cases we recommend leaving it on.
  • The Payload class makes use of a new concept called Representations to provide easier access to the data that you need. With representations it is possible to easily get specific data types and ignore some/all others.
  • Helper libraries CameraHelper and AudioHelper are included in the SDK to ease implementation of camera and audio capture & processing. The libraries are used in the sample applications as well as the SDK UI components.

Getting Started

The DIS UI components provide the easiest path to getting an application up, running and functional. Refer to the documentation for DMSDetectorView as well as the sample application DISDemo for more information.


Sample Applications

   DMSDemo - A full featured sample application with image and audio detection, as well as resolving or detected codes. It includes a history drawer and persists the entries across sessions.

   Sdk2Demo - A more simplistic application showing use of image and audio detection and resolving. This is a good sample to refer to for getting an application up and running quickly with image and/or audio capture using the SDK's helper libraries and lower level components.

   DISDemo - Demonstrates usage of the DMSDetectorView UI component for image and audio detection as well as resolving. The UI component is the easiest way to make use of this SDK, although it does lack some of the customization you can get from using the lower level components.
