I see the camera image for about 1-2 seconds, then the App quits silently to the launcher.

Device: Samsong Galaxy S5 SM G900F Android 9 LineageOS 16-microG (no Google Services) klte

I can provide additional information, but need instructions on how to do that ;)

I don't know of this is the right place. But did anybody try to extract the tracking code (Sendungsnummer) from the new German Post Stamp's Matrix Codes?

That would be a cool feature for Binary Eye

Would you mind attaching the .apk to your /releases for folks without Playstore? Or even better, having your app available at F-Droid? It looks pretty privacy-friendly, so us tin-foils would really appreciate it. For F-Droid, the blob in libs/ might be an issue – but there's always my repo if you can provide the .apk :wink:

Greetings,

I created a WiFi network connection profile -- skynet-guest -- by way of scanning a QR code using Binary Eye and the resulting entry will not allow for "forgetting" the connection profile. The only option provided is "Disconnect".

As a result, I am unable to "Forget" the connection profile.

The WiFi profile also does not show up under the "Saved networks".

I tried clearing Binary Eye's cache and storage to no avail; still no option to forget the connection profile.

Hello! I'm using your great little app for attempting something crazy: data exfiltration via QR codes. See qrxfil for the project details, but suffice to say I am aiming to scan dozens of QR codes of ~1KB payload in quick succession.

Issue: App crashes (back to android home) after ~15 to 20 QR code scans (in ~20 seconds)

Expected behaviour: Scan hundreds of QR codes without crash (at a rate of 1 to 2 per second)

Reproduction steps

Initially using BinaryEye version 1.37.0, reproduced on 1.39.0 (F-Droid)

• Generate a bunch of QR codes of ~1KB data (I used qrxfil on a 500KB file, creating ~500 numbered PNGs to scan)
• Enable Scan Continously
• In an image viewer, open the first QR code image
• When a QR code is recognized (vibration), move to the next one
• After a few dozen, Android shows homepage without an explanation

Conjectures The crash seems to happen after I scan a few dozen codes, each of which shows a Toast containing the 1KB of decoded text (base64 strings), all overlapping with each other. It is possible the Toast creation logic gets an error when drawing one too many, doesn't handle it, and crashes? If so, disabling the Toast of QR contents would make the issue disappear. Worth investigating?

Note I have not captured any logs pointing to reason for homepage, and haven't done any investigation as to what's wrong, am just reporting the issue naively for now. Expect more digging.

Am happy providing logs if I can, and can share sample QR codes that trigger issues.

Hi,

After scaning a barcode, can you add a button to open the application in connection with the code read.

Examples :

• if the code contain an URL → the button can open the webbrowser
• if the code start with mailto: → the button can open the mail client
• if the code is a vCard BEGIN:VCARD → the button can open the contact app
• ...

You can see some other one on this page : https://github.com/zxing/zxing/wiki/Barcode-Contents

Thanks !

The following code may need to be optimized because it produces results like this

This would allow to export the history as CSV file. Currently it works, but the code doesn't look good and only exports the content. I would like to also export the time and the type. Also it allows to export binary data to CSV, does this even make any sense? Suggestions are welcome.

TODO:

• [x] Escape content if needed
• [x] Reorganize usage of the db to be accessed by a repo/usecase ?!
• [x] Add some real res strings, don't use hard-coded stuff...

Look. If I create a new barcode and I'm just going to share/export into a "Simple Draw" (Zeichenblock) app, I do get always the image for "http://schlüsseldienst-frickenhausen.de", an address which I've made once (I know this should've been "//xn--schlusseldienst-frickenhausen-46c.de"). Now if I'm trying to make a new image for example for "https://github.com/metadings", this exported to my Draw app, I do always get the stupid OLD image !

(There is the file intern/Android/data/de.markusfisch.android.binaryeye/cache/shared_barcode.png which I can copy to somewhere else :smiley_cat:)

Right now only specific history items can be shared. It would be good to have an option to share the whole history as a list too.

BTW the app is very good. Light, fast, has all the features it needs (besides sharing the whole history list :) )

Hi, it could be great if we can have some informations about the scanned code. After a scan, you could display his type (Code39, Code128GS1, Datamatrix... ), his lenght, his raw content...

Thanks !

Hi, thank you very much for creating a good app.

Could you add support for multiple rear lenses? If I understand correctly, currently when zooming in, we simply enlarge the image digitally by cropping.

It would be nice if BinaryEye had similar behavior as the system camera. Currently, depending on the zoom, it switches the lens to a more optimal one. I wonder if there is a publicly available Android API that offers this.

The purpose of the function is simple, fast, convenient and effective scanning of codes from near and far.

When attempting to scan barcodes continuously, with a restriction set and/or formats selected, these settings seem to be ignored. I.e., After restricting to UPC A, the app still manages to incorrectly scan (the same barcode as) an EAN 13. I assume the incorrect scan is due to rolling shutter and focus issues, but that doesn't account for these settings being ignored.

Hi Folks, Good day. I hope you're doing great! I'm posting this in the issues section as I didn't find any other place to ask it. I'm researching on how to improve the QR Code decoding performance for cases where the image have some imperfections. I'm comparing several libraries for this use case. BinaryEye is a phenomenal App. I love it and its far superior that most of the other ones that we have around. Thanks Markus Fisch. However, there's some cases where I'm still struggling to have it decode QR Codes. Take the attached one for example. It's a QR Code that is decoded fine using a standard USB Reader. I've also tested it with a proprietary Demo Library (dynamsoft) which, surprisingly, decodes it very easily. Unfortunately, being proprietary and with an unreasonably high price make it non affordable for most cases. Two questions comes to mind:

1. How this proprietary library can decode that image and most of other don't? What kind of "magic" do they do in order to improve the performance?
2. Is there any way we can achieve same results with BinaryEye (or ZXing-cpp)? Is there a way to pre-process the camera image (with brightness/contrast or color threshold filters for example) or change any App/Library parameters that can yield to same results? I'm pasting the same image I used on the attached video for testing. I Appreciate if any of you guys have suggestions on how to improve decoding performance for these scenarios. Thank you and Best Regards.

The tests were done on the Galaxy Note 20 Ultra, with Binary Eye 1.57.0 from F-Droid App Store.

If "Scan continuously" is active and "Ignore duplicates" is disabled, I would assume that it would be possible to scan the same code twice in succession. However, scanning the same code again is only possible if a) another action has taken place in between (opening the menu, closing and opening the app, etc) or b) another barcode was scanned in between.

I'm not sure if this is intended behavior, since this reduces the risk of scanning the same code twice by accident (even tho this is also reduced by the delay between scans). I was trying to get the time between two scans to stop timings. I don't think this is an use case that is common. Therefore I think leaving it as is could also be the right decision.

The Option "Vibrate on detection" does not lead to a vibration on detection on Android 13. On an older device using Android 11, this setting works as expected.

I tried using this code:

fun Context.getVibrator(): Vibrator = if (beforeS) { @Suppress("DEPRECATION") getSystemService(Context.VIBRATOR_SERVICE) as Vibrator } else { (getSystemService(Context.VIBRATOR_MANAGER_SERVICE) as VibratorManager).defaultVibrator }

instead of:

fun Context.getVibrator(): Vibrator = if (beforeS) { @Suppress("DEPRECATION") getSystemService(Context.VIBRATOR_SERVICE) as Vibrator } else { (getSystemService(Context.VIBRATOR_MANAGER_SERVICE) as VibratorManager).defaultVibrator }

inside the Vibrator.kt, sadly that did not solve the problem.

Feel free to ask for tests or more information.

I'm not an Android developer, so the only other idea I had was to set the amplitude of the vibration to 255, but this did not change the behavior.

I tested on a Pixel 4a 5g and a Pixel 4a with Android 13, and on a Fairphone 4 with Android 11.
