Release notes

5.1.0

Improvements:

  • The SDK is now supported on Android 16KB page size devices.
  • Updated target API level to 36 with full support for edge-to-edge UI enforcement introduced in API level 35.

Breaking changes

  • Min Android SDK API level is raised to 21 (Android 5.0)

  • We've changed how RecognizerRunner processes images. Now it can treat Image objects as either video frame or photo frame. Until now, Direct API always processed images as photo frames, not giving ability to recognizers to use time-redundant information for yield better recognition quality.

  • Removed support for x86 architecture:

    • Devices that are based on the Intel x86 architecture, rather than ARM, are no longer supported. x86 and x86_64 architectures are used on very few devices today with most of them being manufactured before 2015, and only a few after that (e.g. Asus Zenfone 4). According to the Device catalog on Google Play Console, these devices make up about 0.5% of all Android devices (97 out of 17278 devices that have an API level of 21 and above support this architecture).

5.0.0

BlinkInput v5 Release Announcement

As of this version, BlinkInput SDK is fully compatible with other Microblink SDKs, which means that you can use it alongside another Microblink SDK in the same application.

Improvements:

  • We've translated the complete SDK to the following additional languages: Malay, Dutch, Hungarian, Serbian, Slovenian, Indonesian, Arabic, Romanian, Chinese traditional, Chinese simplified, Thai, Hebrew, Vietnamese and Filipino.
  • We've made the SDK safe from tapjacking, a form of attack where a user is tricked into tapping something he or she didn't intend to tap. We did this by adding a new security option that prompts the SDK to discard touches when the activity's window is obscured by another visible window. To activate it, use UISettings.setFilterTouchesWhenObscured(true).
  • We've introduced a new FrameRecognitionCallback callback for the RecognizerRunnerView, which is invoked each time a camera frame from a video stream is recognized. Use RecognizerRunnerView.setFrameRecognitionCallback method to set the callback.

Major API changes

  • To ensure compatibility with other Microblink SDKs, we have repackaged all classes. We’ve renamed the root package com.microblink to com.microblink.blinkinput, which is unique to BlinkInput SDK.
  • ScanResultListener interface now has an additional method called when the scanning cannot continue because of an unrecoverable error. You have to implement onUnrecoverableError method. If you're using built-in activities, when onActivityResult is called with RESULT_CANCELED result code, the exception will be available via ActivityRunner.EXTRA_SCAN_EXCEPTION intent extra. If the user canceled the scan, the exception would be null.

Minor API changes:

  • We renamed EMailParser to EmailParser.
  • We renamed some methods:
    • In LicensePlatesParser: getLicensePlateString is now called getLicensePlate.
    • In RegexParser: isUsingSieve is now called shouldUseSieve, setMustStartWithWhitespace is now called setStartWithWhitespace , isMustStartWithWhitespace is now called shouldStartWithWhitespace , setMustEndWithWhitespace is now called setEndWithWhitespace , and isMustEndWithWhitespace is now called shouldEndWithWhitespace .
    • In RawParser: isUsingSieve is now called shouldUseSieve.
  • We've renamed RecogitionMode to RecognitionDebugMode in RecognizerBundle.
  • We've replaced Using time-limited license! warning with Using trial license! warning. The warning message is displayed when using a trial license key.
  • We've deprecated DetectorRecognizer— use DocumentCaptureRecognizerinstead.
  • We've deprecated Pdf417Recognizer — use BarcodeRecognizer instead.

Bug fixes:

  • We've fixed a bug in IBAN parsing which occasionally read the reference number as part of the IBAN.
  • We've fixed the front-facing camera error on Oukitel WP8 Pro.

4.3.0

Breaking change:

Based on the feedback, we have restored support for x86_64 processor architecture. Due to the architecture specifics, there is no guarantee that the scanning process will work equally well as it does on the ARM architectures. The main reason for restoring support is to ease the compliance issue for developers. We distribute SDK with ARMv7, ARM64, x86, and x86_64 native library binaries.

Improvements:

  • We have translated complete SDK to following languages: Croatian, Czech, English, French, German, Italian, Portuguese, Slovak, and Spanish.
  • We improved document detection with DocumentCaptureRecognizer.
  • We are now delivering the complete list of open source dependencies used in the SDK. Please check the open-source-software-used directory.

Minor API changes:

  • We removed RecognizerRunnerView custom attributes: mb_initialOrientation and mb_aspectMode. Use RecognizerRunnerView.setInitialOrientation and RecognizerRunnerView.setAspectMode to configure the attributes in the code.
  • We renamed EMailParser to EmailParser
  • We renamed some methods:
    • LicensePlatesParser: getLicensePlateString to getLicensePlate
    • RegexParser: isUsingSieve to shouldUseSieve, setMustStartWithWhitespace to setStartWithWhitespace , isMustStartWithWhitespace to shouldStartWithWhitespace , setMustEndWithWhitespace to setEndWithWhitespace , isMustEndWithWhitespace to shouldEndWithWhitespace
    • RawParser: isUsingSieve to shouldUseSieve

4.2.0

Breaking changes:

  • We decided to remove support for x86_64 processor architecture. x86 and x86_64 architectures are used on very few devices today; most of them are manufactured before 2015, and they take about 1% of all Android devices, according to the device catalog on Google Play Console. We distribute SDK with ARMv7, ARM64, and x86 native library binaries. Native library x86 in SDK is kept mainly for emulator support.
  • We migrated the SDK to AndroidX dependencies. We replaced previous SDK dependency com.android.support:appcompat-v7 with androidx.appcompat:appcompat.

New features:

  • We added the option to disable Microblink logs in the console output. Use LoggingSettings.disableMicroblinkLogging(), but be careful with this option. We need full log outputs from the application for support purposes. In case of having problems with scanning certain items, undesired behavior on the specific device(s), crashes inside the SDK, or anything unmentioned, we will need a full log from your side. If you disable Microblink logs, you won't be able to provide us this information. Hence support might be limited.
  • We added support for capturing images of various documents (A4, or some other format):
    • Use DocumentCaptureRecognizer and DocumentCaptureUISettings.
    • DocumentCaptureUISettings launches activity that uses DocumentCaptureOverlayController, which is designed for taking cropped high resolution document images and guides the user through the document capturing process. The overlay can be used only with DocumentCaptureRecognizer.
  • It’s possible to set the theme of the provided scan activity, launched from the UISettings, by using UISettings.setActivityTheme

Improvements:

  • We improved VinParser:
    • We added support for Renewal Identification Number (RIN) - DMV California format.
  • We improved camera performance on some Samsung devices.

Minor API changes:

  • We removed RecognizerRunnerView custom attributes: mb_initialOrientation and mb_aspectMode. Use RecognizerRunnerView.setInitialOrientation and RecognizerRunnerView.setAspectMode to configure the attributes in the code.
  • RecognizerRunnerFragment extends androidx.fragment.app.Fragment, instead of the deprecated android.app.Fragment.
  • All provided scan activities extend AppCompatActivity and they are final.
  • RecognizerRunner.getSingletonInstance() does not throw FeatureNotSupportedException anymore.
  • We added a new API for configuring camera options in UISettings. Use UISettings.setCameraSettings, which accepts an object of CameraSettings type.
  • FieldByFieldOverlayController is now configured by using FieldByFieldOverlaySettings instead of FieldByFieldUISettings.
  • Recognizer now only has one type parameter.
  • Recognizer.Result no longer has any type parameters.
  • We moved some classes to new packages.

Bugs that we fixed:

  • Crash when using Direct API on high resolution com.microblink.image.Image from HighResImageWrapper.
  • Problems with aspect ratio of camera preview on Huawei Mate 10.
  • Crash on some devices that use armeabi-v7a ABI. The SDK was unable to reserve address space due to memory fragmentation.
  • Camera busy error in camera management that was happening during the quick closing and opening of the camera.
  • Rare crash on Samsung J5 Prime which has been caused by race condition during the initialization of the native camera frame.
  • All default scan activities correctly set volume to media instead of the ring.
  • All default scan activities now apply a secure flag if enabled in UISettings.
  • Scanning bug on devices with problematic camera resolution, which caused that the SDK was unable to scan the data. Known affected devices were: OnePlus 6T, OnePlus 7 Pro, and Vivo V15.

4.1.0

New features:

  • enabled capturing of high resolution camera frames:
    • When custom UI integration is performed, enable this functionality by using method RecognizerRunnerView.setHighResFrameCaptureEnabled and use RecognizerRunnerView.captureHighResImage to capture image
    • When using provided scan activities, high resolution full camera frames taken at the moment of successful scan are returned if this option is enabled through UISettings. Concrete UISettings which implement interface HighResSuccessFrameCaptureUIOptions support this feature.

Improvements for existing features:

  • added option to force overlay orientation for BarcodeOverlayController (BarcodeScanActivity) - use BarcodeUISettings.setForcedOrientation(OverlayOrientation)
  • RecognizerRunnerView is lifecycle-aware now, it implements android.arch.lifecycle.LifecycleObserver interface
  • improved image return processor:
    • the processor now estimates detected (dewarped) document image quality and returns the best quality dewarped image from the best quality detection
  • BarcodeScanActivity by default does not show result dialog after scan
  • updated default UI icons

Minor API changes:

  • Scanning timeout that can be configured by using RecognizerBundle.setNumMsBeforeTimeout is by default set to RecognizerBundle.TIMEOUT_INFINITY, which means that timeout is disabled by default. Previous default timeout value was 10 seconds.
  • renamded enum com.microblink.uisettings.options.ShowOcrResultMode to com.microblink.uisettings.options.OcrResultDisplayMode
  • for all UISettings classes which support setting of OCR result display mode, renamed method setShowOcrResultMode to setOcrResultDisplayMode

Bug fixes:

  • fixed crashes on Nexus 6
  • removed incorrect autofocus check that was performed before concrete camera type is chosen
  • fixed crash on some devices when using VIDEO_RESOLUTION_MAX_AVAILABLE
  • fixed problems in camera management:
    • default camera surface is TextureVeiw for devices that use Camera1 API, otherwise SurfaceView is used
  • fixed camera autofocus problems on Samsung S9/S9+ when optimisation for near scanning is enabled
  • fixed autofocus problems in Field by field scanning on Huawei P20 pro, Huawei P20 and Huawei P20 lite
  • fixed bug which caused that results from the previous scan are cleared when the scan activity is run again and entities which have produced results are not used in the new scan
  • various other bug fixes and improvements

4.0.0

  • new API, which is not backward compatible. Please check README and updated demo applications for more information, but the gist of it is:
    • RecognizerView has been renamed to RecognizerRunnerView and Recognizer singleton to RecognizerRunner
    • SegmentScanActivity has been renamed to FieldByFieldScanActivity
    • RandomScanActivity does not exist anymore
    • previously internal Recognizer objects are not internal anymore - instead of having opaque RecognizerSettings and RecognizerResult objects, you now have stateful Recognizer object that contains its Result within and mutates it while performing recognition.
      • similarly we now have stateful Parser and Detector objects
      • introduced new Processor object type
      • For more information, see README, updated demo applications and this blog post
    • added RecognizerRunnerFragment with support for various scanning overlays in a manner similar to iOS API. This now allows you to use built-in UI, which was previously strictly available for built-in activities, in form of fragment anywhere within your activity. Full details are given in README and in updated demo applications.
  • new licence format, which is not backward compatible. Full details are given in README and in updated applications, but the gist of it is:
    • licence can now be provided with either file, byte array or base64-encoded bytes
  • introduced preview version of next generation DeepOCR. Check BlinkInputRawOcrSample to see how it can be enabled.

3.4.0

New features:

  • Added VinRecognizer for scanning VIN (Vehicle Identification Number) barcodes
  • Added unified BarcodeRecognizer for scanning various tipes of barcodes
    • ZXingRecognizer and BarDecoderRecognizer are deprecated, BarcodeRecognizer should be used for all barcode types that are supported by these recognizers
  • added support for reading mirrored QR codes:
    • affects all recognizers that perform QR code scanning
  • introduced GlareDetector which is by default used in all recognizers whose settings implement GlareDetectorOptions:
    • when glare is detected, OCR will not be performed on the affected document position to prevent errors in the extracted data
    • if the glare detector is used and obtaining of glare metadata is enabled in MetadataSettings, glare status will be reported to MetadataListener
    • glare detector can be disabled by using setDetectGlare(boolean) method on the recognizer settings
  • added QuadDetectorWithSizeResult which inherits existing QuadDetectorResult:
    • it's subclasses are DocumentDetectorResult and MRTDDetectorResult
    • returns information about physical size (height) in inches of the detected location when physical size is known
  • added support for characters { and } in OCR_FONT_VERDANA to OCR engine

Minor API changes:

  • Date fields in recognition results are returned as com.microblink.results.date.Date class which represents immutable dates that are consisted of day, month and year
  • OcrLine.getChars() method returns CharWithVariants array. OCR char is defined by all its parameters (value, font, position, quality, etc.) and for each resulting char it is possible to have multiple variants. For example it is possible to have same char value with different font.
  • RegexParserSettings and RawParserSettings now work with AbstractOCREngineOptions, which is a base class of BlinkOCREngineOptions
    • default engine options returned by method getOcrEngineOptions for both parser settings return instance of BlinkOCREngineOptions
  • BlinkOCRRecognizerSettings is now deprecated and will be removed in v4.0.0
    • use DetectorRecognizerSettings to perform scanning of templated documents
    • use BlinkInputRecognizerSettings for segment scan or for full-screen OCR
    • until v4.0.0, BlinkOCRRecognizerSettings will behave as before, however you are encouraged to update your code not to use it anymore
  • DocumentClassifier interface is moved from com.microblink.recognizers.blinkocr to com.microblink.recognizers.detector package and DocumentClassifier.classifyDocument() now accepts DetectorRecognitionResult as parameter for document classification

Improvements for existing features:

  • improved TopUpParser:
    • added option to return USSD code without prefix
  • improved IbanParser:
    • improved extraction of IBANs without prefix and introduced setAlwaysReturnPrefix option to always return prefix (country code)
    • added support for french IBANs
  • enabled reading of Pdf417 barcodes having width/height bar aspect ratio less than 2:1
  • improved date parsing:
    • affects date parser and all recognizers which perform date parsing

Bug fixes:

  • fixed returning of images inside TemplatingAPI for frames when document was not correctly detected
  • Fixed bug in SegmentScanActivity:
    • scan results are no longer hidden on shake event

  • LibBlinkInput is now fully ProGuard-compatible, i.e. you no longer need to exclude com.microblink.** classes in your ProGuard configuration
  • removed support for Android 2.3 and Android 4.0 - minimum required Android version is now Android 4.1 (API level 16)
  • removed isItalic and isBold getters from OcrChar class
    • they always returned false, since OCR engine cannot accurately detect that
  • removed setLineGroupingEnabled and isLineGroupingEnabled from BlinkOCREngineOptions because disabling line grouping completely destroyed the OCR accuracy
  • improved TopUpParser:
    • added option to enable all prefixes at the same time (generic prefix)
    • added suport for 14 digits long sim numbers in addition to existing lengths (12, 19, 20)
  • DateParser can parse dates with month names in English (either full or abbreviated), if this option is enabled
  • added support for polish IBAN without PL prefix to IBANParser
  • prefixed custom attributes to avoid name collisions with attributes from other libraries:
    • CameraViewGroup: renamed animateRotation to mb_animateRotation, animationDuration to mb_animationDuration, rotatable to mb_rotatable
    • BaseCameraView: renamed initialOrientation to mb_initialOrientation, aspectMode to mb_aspectMode

3.2.0

  • enabled reading of longer ITF barcodes

2.7.0

  • support for parsing Vehicle Identification Numbers (VINs)
  • renamed BlinkOCRActivity to SegmentScanActivity
  • added RandomScanActivity which is similar to SegmentScanActivity but it does not force the user to scan text segments in the predefined order
  • improved autofocus support on SGS6 and SGS7
  • fixed memory leak in RecognitionProcessCallback, leak was caused by Recognizer singleton holding reference to both Context and MetadataListener even after termination

2.6.0

  • added support for using detectors to perform detection of various documents
  • added support for combination of detectors with BlinkOCR recognizer to perform OCR of only parts of detected documents
    • refer to documentation and demo apps for example
  • updated BlinkOCRActivity, through ScanConfiguration it is now possible to make some scan field optional (user can skip it) and set the field size

2.5.0

  • FailedDetectionMetadata, PointsDetectionMetadata and QuadDetectionMetadata have been replaced with DetectionMetadata which now holds a DetectorResult
    • DetectorResult is more flexible as it allows more different detection types to be added in future
  • fixed several possible crashes in camera management
  • fixed autofocus bug on LG devices when metering areas or non-default zoom level were set
  • fixed autofocus bug on LG G4 (not related to bug above)
  • added option to set the OCR document type in BlinkOCREngineOptions

  • fixed bug in camera layout in certain aspect ratios of camera view
  • fixed bug in segment scan when put on landscape activity
  • fixed bug in handling setMeteringAreas
  • setMeteringAreas now receives boolean indicating whether set areas should be rotated with device
  • added support for specifying camera aspect mode from XML

2.1.0

  • fixed crash that occurred when detection image was being sent from native to Java
  • fixed issue that cause irrationaly refusal to scan anything on high-end devices
  • fixed bug in scanning 1D barcodes with ZXing when scanning region was set
    • the bug caused not to honor set region
  • when embedding RecognizerView into custom scan activity, you no longer need to take care of whether runtime permissions are set or not. You can now simply pass all lifecycle events to RecognizerView and if camera permission is denied, a new callback method onCameraPermissionDenied of CameraEventsListener will be invoked to give you chance to ask user for permissions
    • please refer to updated demo apps for example of new callback
  • IMPORTANT - onScanningDone callback method does not automatically pause scanning loop anymore. As soon as onScanningDone method ends, scanning will be automatically resumed without resetting state
    • if you need to reset state, please call resetRecognitionState in your implementation of onScanningDone
    • if you need to have scanning paused after onScanningDone ends, please call pauseScanning in your implementation of onScanningDone. Do not forget to call resumeScanning to resume scanning after it has been paused.
  • pauseScanning and resumeScanning calls are now counted, i.e. if you call pauseScanning twice, you will also need to call resumeScanning twice to actually resume scanning
    • this is practical if you show multiple onboarding views over camera and you want the scanning paused while each is shown and you do not know in which order they will be dismissed. Now you can simply call pauseScanning on showing the onboarding view and resumeScanning on dismissing it, regardless of how many onboarding views you have
    • if you want to show onboarding help first time your scan activity starts, you can call setInitialScanningPaused(true) which will ensure that first time camera is started, the scanning will not automatically start - you will need to call resumeScanning to start scanning after your onboarding view is dismissed
  • added support for x86_64 architecture

2.0.0

  • new API which is easier to understand, but is not backward compatible. Please check README and updated demo applications for more information.
  • removed support for ARMv7 devices which do not support NEON SIMD
    • this enabled us to increase recognition speed at cost of not supporting old devices like those using NVIDIA Tegra 2
    • you can check this article for more information about NEON and why we use it
  • added official support for Android 6.0 and it's runtime camera permissions
    • if using provided BlinkOCRActivity, the logic behind asking user to give camera permission is handled internally
    • if integrating using custom UI, you are required to ask user to give you permission to use camera. To make this easier, we have provided a CameraPermissionManager class which does all heavylifting code about managing states when asking user for camera permission. Refer to demo apps to see how it is used.
  • BlinkOCR now depends on appcompat-v7 library, instead of full android-support library.
    • even older versions of BlinkOCR required only features from appcompat-v7 so we now decided to make appcompat-v7 as dependency because it is much smaller than full support library and is also default dependency of all new Android apps.
  • completely rewritten JNI layer which now gives much lower overhead in communication between Java and native code
    • in our internal tests, this yielded up to 3 times better performance in OCR
  • fixed issue with Nexus 5X upside down camera
  • when using DirectAPI, recognized Bitmap is not recycled anymore so it can be reused

1.9.0

  • fixed auto-exposure bug on Nexus 6
  • improved OCR quality and performance
  • fixed autofocus issue on devices that do not support continuous autofocus
  • support for defining camera video resolution preset
    • to define video resolution preset via Intent, use BlinkOCRActivity.EXTRAS_CAMERA_VIDEO_PRESET
    • to define video resolution preset on RecognizerView, use method setVideoResolutionPreset

  • fixed segmentation fault on recognizer reconfiguration operation
  • fixed freeze when camera was being quickly turned on and off
  • fixed bug in IBAN parser that caused not to parse IBAN's that contain letters, such as in UK, Ireland or Netherlands
  • ensured RecognizerView lifecycle methods are called on UI thread
  • ensure onCameraPreviewStarted is not called if camera is immediately closed after start before the call should have taken place
  • ensure onScanningDone is not called after RecognizerView has been paused, even if it had result ready just before pausing
  • default maximum number of chars in raw parser is now 3000 (it used to be 600)
  • it is now possible to define maximum allowed number of char recognition variants via BlinkOCREngineOptions. Default value is 0.
  • when calling onDisplayOcrResult callback, make sure OCR char recognition variants are not sent to Java - this is both slow and not required
  • added support for using BlinkOCR as camera capture API. To do that, implement following:
    • when using RecognizerView do not call setRecognitionSettings or call it with null or empty array
    • implement ImageListener interface and set the listener with setImageListener
    • as a reminder - you can process video frames obtained that way using direct API method recognizeImageWithSettings
  • reorganized integration demo apps
    • BlinkOCRSegmentDemo shows how to use simple Intent-based API to scan little text segments. It also shows you how to create a custom scan activity for scanning little text segments.
    • BlinkOCRFullScreen shows how to perform full camera frame generic OCR, how to draw OCR results on screen and how to obtain OcrResult object for further processing. This app also shows how to scan Code128 or Code39 barcode on same screen that is used for OCR.
    • BlinkOCRDirectAPI shows how to perform OCR of Bitmap object obtained from camera
    • all demo apps now use Maven integration method because it is much easier than importing AAR manually
