Did you try this one? https://play.google.com/store/apps/details?id=com.google.zxing.client.android

I already searched through old issues and one of the issue mentioned about trying this app. So yes I tried with it, didn't work.

For the open-source version, for which this repository is, it works with the ZXing client application. Just tested current master.

The one from Play-Store seems to be hosting it's own version of the library internally, because it asks for access to camera. Is it possible that you denied this permission?

I have the same problem as above. Google Authenticator does have permissions to take pictures and videos. I have installed the barcode scanner separately as suggested by ThomasHabets. I am recieving the same error as above.

I'm having the same problem with OnePlus 3T, android version 6.0.1. I don't know how to fix :-/

[ThomasHabets]

Did you try the app @capi suggested?

Oh, you're probably not using opensource, so that probably won't help.

[hwong557]

I have instead the suggested app. I guess I am not using the opensource version. I installed the app from the play store.

[brunano21]

Me too. I have installed the Play Store version.

meizu m5 global firmware. The same thing. Cant scan due to barcode scanner unavailability.

I have the same problem on Moto G Android 5.1. I installed Google Play version. I gave camera permissions to ZXing bar scanner, I also tried to reinstall it.

Same issue with:
model Nexus 5
Android 6.0.1
Authenticator: 4.74

I have re-enabled the Camera permission for Authenticator as it was turned off (maybe by the new version of Authenticator ?) but without any success.

hey, when it would be fixed???

This repo is only about the open source version, not the <brand> Store versions.

Pasting standard boilerplate:

FYI: The version in Google Play Store / Apple App store is not the same as this opensource version. They've diverged. This opensource version is also unlikely to end up in the app stores. This open source version doesn't get much love, but I'll accept well-written pull requests. But don't expect this feature to be implemented by Google.

I solved this problem by having Google authenticator installed, then installing QR & Barcode scanner (https://play.google.com/store/apps/details?id=com.gamma.scan). When I set up a new account for my Google authenticator I scanned the code with the QR scanner which gives me a link that opens up the Google authenticator with the confirmation code. I hope that helps for some people.

I have moved to Authy instead - It's better in everything.
