I have a new Nexus 5X that says "Manual sign in required" because the QR code scanner is not available. I've verified my Google Play Services version is up-to-date (9.0.83), and I've reinstalled 1Password from the play store a couple of times. Hasn't been an issue on my other devices running the same versions of services and 1P (Nexus 6P, Samsung GS7).

What do I do now? I tried tapping on the Scan the barcode bar at the top. That did not seem to do anything, nut maybe I needed to press and hold. But no, that didn't work either. This is obviously very basic Android stuff that I have yet to learn.

@danco Once the QR code is recognized, scanning should be automatic. You don't need to do anything else. That said, what are you scanning from? Are you using the rear-facing camera and scanning from your Emergency Kit on another device or on paper, or are you scanning from the Android screen? If you uninstall/reinstall 1Password on Android, are you able to scan after?

After a run of bad luck, I've had to factory reset two different Nexus 5x phones three times over the past ~2 weeks. The first two times, I was able to scan the QR code no problem. The most recent time, I received the above referenced error code about Google Play Services and QR code scanner, which led me to this thread. (Hi y'all, used to be a regular but been away for quite a while...)

Not strictly within glide. You would probably have to use the image picker to upload an image of the barcode and integrate a third party process to read and return the result of that QR code. Or, you would have to use a third party scanning app that can update your tables.

QR Code is a two-dimensional version of the barcode, typically made up of black and white pixel patterns. Denso Wave, a Japanese subsidiary of the Toyota supplier Denso, developed them for marking components in order to accelerate logistics processes for their automobile production. Now, it has found its way into mobile marketing with the widespread adoption of smartphones. "QR" stands for "Quick Response", which refers to the instant access to the information hidden in the Code.

Yes! For most iOS and Android users, a QR Code scanner is already built into the native camera app. Simply open the camera app and hold it over any Codes until a notification pops up. You don't even have to press any button to scan the Codes.

You can use code scanning to find, triage, and prioritize fixes for existing problems in your code. Code scanning also prevents developers from introducing new problems. You can schedule scans for specific days and times, or trigger scans when a specific event occurs in the repository, such as a push.

If code scanning finds a potential vulnerability or error in your code, GitHub displays an alert in the repository. After you fix the code that triggered the alert, GitHub closes the alert. For more information, see "Managing code scanning alerts for your repository."

To monitor results from code scanning across your repositories or your organization, you can use webhooks and the code scanning API. For information about the webhooks for code scanning, see"Webhook events and payloads." For information about API endpoints, see "Code Scanning."

CodeQL is the code analysis engine developed by GitHub to automate security checks. You can analyze your code using CodeQL and display the results as code scanning alerts. For more information about CodeQL, see "About code scanning with CodeQL."

Code scanning is interoperable with third-party code scanning tools that output Static Analysis Results Interchange Format (SARIF) data. SARIF is an open standard. For more information, see "SARIF support for code scanning."

You can run third-party analysis tools within GitHub using actions or within an external CI system. For more information, see "Configuring advanced setup for code scanning" or "Uploading a SARIF file to GitHub."

The tool status page shows useful information about all of your code scanning tools. If code scanning is not working as you'd expect, the tool status page is a good starting point for debugging problems. For more information, see "About the tool status page for code scanning".

Documentation for the Sophos Intercept X Mobile QR code scanner should probably include something about the limitation of the QR code scanner. I created a 61x61 plain text QR Code using an on-line service, and scanned it three times in a row, the three results were:

By experimenting, I found the problem to be that your scanner can't handle a QR code that fills more than about half the height of the scan window, and it didn't matter if I was scanning the QR code displayed 15 cm square on a monitor or printed 14 cm square on paper. If I held the phone far enough away from the print, it read it properly; too close and it gave me random 8-digit numbers. (In case the problem has something to do with the camera, I'm using a new Samsung Galaxy S8.) Here are 3 identical 81x81 test codes at 200PPI, 300PPI and 600PPI. Even the 200 PPI one doesn't scan properly if I hold the camera too close to it, but far enough so the entire code fits in the scan window.

Hello good afternoon, I have a question about QR code scanner. I currently created an app that has a barcode scanner and i want to try to send the information that i scan, to a google sheets .csv spreadsheet. For example if i scan a QR code i want the information to show in the .csv file with the name under the name column, the number under the number column, etc. I actually have 2 questions:

Would it be possible to accomplish the same by scanning a QR code with my barcode scanner and then sending that information to another screen in my app where i have a textbox and spinner, what i mean by this is that if i scan the QR code can i automatically fill in my textbox and spinner fields from that QR code and then click the save button so that the name and number from that specific QR code saves into the .csv? (i have already successfully connected my textboxes and spinners to a specific .csv i created, so i was curious if this method was possible?) Thank you so much for the help in advance. I always appreciate the input.

QRCode Monkey is one of the most popular free online qr code generators with millions of already created QR codes. The high resolution of the QR codes and the powerful design options make it one of the best free QR code generators on the web that can be used for commercial and print purposes.

Also I take advantage of it, is it possible to insert a logic that if the scanned qr code is already present in the record archive, a pop up is shown? as what I would like to create is an app for merchants who will have to scan some qr code (coupon), but which are valid only once. Do you have any advice?

Regarding your QR Coupon, I think I would solve this by having the merchant scan the QR code which opens up a screen that has the unique coupon and a validate button (redeem) and cancel button. The coupon collection should have a True/False property and the redeem button should validate only if the coupon is set to either false or true (however you want to set that logic).

As for the merchant scanning the QR code, I understand what you mean. But is it possible after scanning to perform an automatic check (based on the ver / false if it already exists), which denies the confirmation of the coupon code, on the next screen?

The idea is, you have your collections set for either scenario that best matches your case (follow or friend request), but instead, using coupons as an item that is moved from a True column to False column, vice versa, on your User Collection. Columns being relationships between User Collections and Coupon Collection. Using the QR scanner to update current scan coupon to the right column.

If you can imagine, there would be a list of coupons from different merchants. A user can redeem by tapping on a redeem button that opens current coupon QR code. A merchant then scans the QR code that updates the coupon for the logged in user to a redeemed column.

In the quick settings, the Qr code scanner is stuck "updating." I have cleared the cache for google play services and updated the moto.camera.2 app but the thing continues to state updating and won't launch.

I had the same problem. It seems to be some google bug which sometimes happen. In my case google code scanner was working one day but on the next day does not without any code change. I just deleted data of Google Play services app. After that I got error CODE_SCANNER_UNAVAILABLE (Required code scanner module is not available yet) see and this means that just wait a few seconds and try again and google code scanner will work - this is just in local development when app is not installed via play store. In usual case google installs code scanner with app if you have in AndroidManifest.xml.

Great to debug is android app in play store =com.khandev.qrcodescanner which uses google code scanner library. You can test that when you delete play services data and install that app from play store and open it after several second later google code scanner is working so lib was pre-installed with app before first app use.

UPDATE 1: we do not recommend this lib in prod, very unreliable, we must stop using it immediatelly, it failures on many different devices (Google code scanner "Failed to scan code."). Google has reported bug but did not solve it

3.) Doc ( -kit/vision/barcode-scanning/code-scanner#configure_your_app ) says when you add into AndroidManifest.xml google play store will install lib within the app. It is not true. I have tested it: installed app from play store, opened app at home screen and wait many minutes (to give google chance to download and install library) but in about 10 minutes later I navigated in app to screen when google code scanner is used and I got error CODE_SCANNER_UNAVAILABLE ( _SCANNER_UNAVAILABLE ) so google did not prepared it at all! Google starts downloading and installing code scanner now after first use NOT AFTER APP INSTALL as said in doc, so it is not acceptable for user to say to him to wait several seconds or minutes (depending on connection speed) and try again. I do not wish to download it manually using many additional Java/Kotlin lines of code when it should work out of the box by doc. ff782bc1db
