v8.0.0

PDF417.mobi v8 Release Announcement

As of this version, PDF417.mobi 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 complete SDK to the following languages: Arabic, Chinese traditional, Chinese simplified, Croatian, Czech, Dutch, English, Filipino, French, German, Hebrew, Hungarian, Indonesian, Italian, Malay, Portuguese, Romanian, Serbian, Slovak, Spanish, Slovenian, Thai and Vietnamese.
• We added the option to disable Microblink logs in the console output. Use LoggingSettings.disableMicroblinkLogging(). 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 SDK or anything unmentioned, we will need a full log from your side. If you disable Microblink logging, you won't be able to provide us this information. Hence support might be limited.
• 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.
• 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.
• We've improved camera performance on some Samsung devices.

Major API changes:

• To ensure compatibility with other Microblink SDKs, we have repackaged all classes. We have renamed the root package com.microblink to com.microblink.blinkbarcode, which is unique to PDF417.mobi SDK.
• SDK has been migrated to AndroidX dependencies - previous SDK dependency com.android.support:appcompat-v7 has been replaced with androidx.appcompat:appcompat
• 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've deprecated Pdf417Recognizer - use BarcodeRecognizer instead.
• We've introduced new API for configuring camera options on UISettings - use UISettings.setCameraSettings, which accepts object of CameraSettings type.
• RecognizerRunnerFragment extends androidx.fragment.app.Fragment, instead of deprecated android.app.Fragment.
• All provided scan activities extend AppCompatActivity.
• We've removed RecognizerRunnerView custom attributes: mb_initialOrientation and mb_aspectMode. Use RecognizerRunnerView.setInitialOrientation and RecognizerRunnerView.setAspectMode to configure the attributes in the code.
• We've changed default IntentDataTransferMode to IntentDataTransferMode.PERSISTED_OPTIMISED. It can be configured by using MicroblinkSDK.setIntentDataTransferMode.
• 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 renamed RecogitionMode to RecognitionDebugMode in RecognizerBundle.

Bug fixes:

• We've fixed camera busy error in camera management that was happening during the quick closing and opening of the camera.
• We've fixed rare crash on Samsung J5 Prime caused by race condition during the initialization of native camera frame.
• We've fixed problems with aspect ratio of camera preview on Huawei Mate 10.
• We've fixed crash when using Direct API on high-resolution com.microblink.image.Image from HighResImageWrapper.
• We've fixed race conditions in camera management, which in some cases caused that the camera was unable to resume after it has been paused.
• We've fixed the front-facing camera error on Oukitel WP8 Pro.

v7.2.1

Bug fixes:

• fixed scanning bug for devices with problematic camera resolution, which caused that SDK was unable to scan data, known affected devices were: OnePlus 6T, OnePlus 7 Pro and Vivo V15

v7.2.0

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
• 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.

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 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

v7.1.0

Bug fixes

• fixed crash that could happend when calling reconfigureRecogizers on RecognizerRunnerView

Improvements for existing features

• added support for nonstandard pdf417 barcodes which wrongly encode number of data codewords

Minor API changes

• PointSetView is now in com.microblink.view.viewfinder.points package
• BarcodeFormat has been renamed to BarcodeType
• USDLRecognizer has been renamed to UsdlRecognizer
• updated BarcodeRecognizer:
  • casing of several methods has been updated: setScanPdf417, setScanQrCode, setScanDataMatrix, setScanEan13, setScanEan8, bsetScanItf, setScanUpca, setScanUpce
  • setUncertainDecoding renamed to setScanUncertain
  • setInverseScanning renamed to setScanInverse

v7.0.0

• 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
  • Pdf417ScanActivity has been renamed to BarcodeScanActivity
  • 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. For more information, see README and updated demo applications
  • 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 Pdf417ScanActivity, 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

v6.4.0

• LibPDF417 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)
  • devices with Android 4.0 and earlier take less than 2% of market share and is very costly to support them
• removed support for armeabi devices and ARMv7 devices without NEON SIMD support
  • support for ARMv7 devices with NEON support still remains

v6.3.0

• fixed UnsatisfiedLinkError that happened on pre-Lollipop devices and was introduced in v6.2.1
