@vknow360
How can I use the logo path?

vknow360 · October 24, 2022, 4:02am

@Joejsanz here is an example. Logo should be an image file (as small as possible) located in external storage.

@vknow360
Perfect, I'll give it a try, thank you very much.

Hi @vknow360, Is it possible to use flashlight when scanning?

vknow360 · November 5, 2022, 10:12am

Hi @Joejsanz , the extension doesn't scan qr codes. It reads them from the file so no need of flashlight.

ChangeLog Version 5.2

Internal changes in reader method to increase its efficiency by a huge. Now, you can provide it a non-pure barcode which may have other objects too, and it'll correctly read from there.
BarCodeDecoded event's parameters can be either a list or string now, based on number of barcodes found in the image. In short, it is possible to read multiple barcodes from an image.

Hello. I tested the apk file you provided for your plugin and got an error. In the apk you provided, the QR Code was not saved on my device after it was generated, I did not see it saved. I have already added a video about this below.

Hello. I cannot generate the QR Code, the QR Code is not registered on my device. Waiting for your response, thanks.

You appear to be using Niotron, please ask on that community

ahmetkirkzade · September 6, 2023, 5:31pm

which community should I ask?

TIMAI2 · September 6, 2023, 5:44pm

Niotron

ahmetkirkzade · September 6, 2023, 7:22pm

but I couldn't find this extension in the niotron community.

TIMAI2 · September 6, 2023, 7:50pm

The issue is that we do not know if your problem is caused by Niotron or by the extension. Develop the same app (or an example) in AppInventor, then we can hopefully help you.

vknow360 · September 6, 2023, 11:53pm

If you read the documentation carefully, you'll find I have clearly mentioned that extension works with absolute file paths.
/qr.png is definitely not an absolute path.

ahmetkirkzade · September 7, 2023, 1:50pm

Yes, I saw that you stated that the file path must be absolute. I did as in the example you gave below, but it didn't work, so I asked and I don't understand why you are angry.

Not sure what should I say.

ahmetkirkzade · September 7, 2023, 2:08pm

I was trying another method here, that's why I posted this, I already tried the example you gave.

vknow360 · September 7, 2023, 2:09pm

Post an example aia demonstrating your issue. Aia must be of AI2.

ahmetkirkzade · September 7, 2023, 2:24pm

I downloaded the aia file you gave in the kodular community and tried to do it from there but it didn't work.
In the block in the picture you showed me, the file location is written as "/qr.png" because the GenerateBarCode block was like this in your aia file:
blocks(12)
This is what I did for this reason.
