            No efficient open source solutions found for scanning GS1 Databar Expanded barcodes on iOS using React-Native.

            Tried Zxingify-ObjC as a native module but the scanning is poor on newer iPhones (11 Pro, 12).

            Tried react-native-barcode plugin. Doesn't support GS1 Databar plugin using the camera scanner, but does support scanning GS1 Databar from static images.

            Finally went for a paid SDK: Cognex.

            Hope this helps someone who runs into the same problem.

            Android MLKit scan QRcode only on center of screen
            Asked 2021-Jan-19 at 19:00

            I implemented firebase MLKit to scan QRCode, it is scanning, but it is scanning all QRcode on screen. I need to scan only QRCode that are captured on the center (has arrow ImageView on the center), how can I do it?

            I tried to crop on the Analisys function (inside analysisUseCase?.setAnalyzer)

            imageProxy.cropRect()

            I tried to crop on the processImageProxy function. But with no success, I think that I can't crop with this

            ANSWER

            Answered 2021-Jan-19 at 19:00

            imageProxy.cropRect() only put a metadata in the image, but not do the cropping operation. For static image, you could convert to bitmap, and crop. A better way is to filter out the results when you have all the returned barcode with the detected barcode boundingbox.

            Within MLKit, we are adding supports for image cropping.

            ML Kit Barcode process fails due to Image is already closed
            Asked 2020-Oct-09 at 22:48

            I'm looking for a few days how I can read a QR code using ML Kit and CameraX. The process of the input image returns always a failure "IllegalStateException: Image is already closed". I have looked on different forums, but I can not find what I'm doing wrong. I think I'm following the Google documentation, but it won't work.

            This is what I'm doing in my MainActivity:

            1. I create a textureView which shows me the input of my camera
            2. I start my camera (after checking the necessary rights)
            3. I setup a "preview" use case
            4. I setup a "Image Analysis" use case
            5. I set an analyzer which creates an InputImage which is passed to the Barcode scanner process
            6. Set my LifeCycle with the use cases "preview" and "image analysis"

            I'm using CameraX version "1.0.0-alpha04" and "com.google.mlkit:barcode-scanning:16.0.3".

            build.gradle

            ...

            ANSWER

            Answered 2020-Oct-09 at 21:32

            I am not 100% sure whether this is related, but could you try updating your CameraX dependencies to the latest version? Yours is 1.0.0-alpha04, while the latest is 1.0.0-beta10. https://developer.android.com/jetpack/androidx/releases/camera

            For the API you are using - setImageReaderMode(ImageAnalysis.ImageReaderMode.ACQUIRE_LATEST_IMAGE), I cannot find it any more on the CameraX dev site: https://developer.android.com/reference/androidx/camera/core/ImageAnalysis

            As for .setImageQueueDepth(1), seems it doesn't work for the default strategy: https://developer.android.com/reference/androidx/camera/core/ImageAnalysis.Builder#setImageQueueDepth(int)

            Another small suggestion: you currently create a new BarcodeDetector in each frame, which could be slow. Creating once outside the analyzer and reuse the same instance could be better.

            Hope some of the points help :)

            After calling zxing scanner, I go back to my activity but in a new instance
            Asked 2020-Jul-29 at 14:02

            I use the library zxing-android-embedded in my Android App. Before calling initiateScan() method to start the scanner from my activity, I set a class variable scanedItemId to know on which item I clicked to scan.

            My issue is that when the scanner activity finished, it goes back to my activity, but in a new instance and not the initial one (I checked with a break point in the onCreate method). So, my class variable is null. What can I do to keep my initial activity instance live and be sure the scanner goes back to it?

            You asked:

            What can I do to keep my initial activity instance live and be sure the scanner goes back to it?

            You can't. When your app goes to the background and the scanner app needs resources, Android will kill your app to make the resources available to the scanner app. This is normal and your app needs to be made robust enough to deal with this. If you need to keep track of your app's state so that you can continue when your app returns to the foreground, then you need to save that information somewhere persistent. You have choices:

            • SharedPreferences
            • SQLite database
            • Use a file
            • Implement onSaveInstanceState()
