@Rene1898

This extension is fantastic

Thank you.

@Rene1898

Unfortunately, data matrix does not work, although it is in the available bar formats.

Identified, working on a fix.

[Rene1898 (René)]

Just a small question (I know I just can test it, but this goes quicker) if data matrix is possible now?

[vknow360 (Sunny Gupta)]

Yes, in APK , not sure about companion.

So I downloaded the extension but it doesnt seem to work for me.

I have this but it shows this error: /qr.png: open failed: EROFS (Read-only file system) I am running android 11 on a s20 FE. Also If I want to create a barcode do I just change “QR_CODE” to “BAR_CODE” ?

@Ruubgaming

/qr.png

You need to prefix external storage path which in your case is App Specific Directory.
So complete path should look like /storage/emulated/0/Android/data/package_name/files/qr.png

@Ruubgaming

Also If I want to create a barcode do I just change “QR_CODE” to “BAR_CODE” ?

Simply no.
Bar Code is a collection of types like CODE_39 , CODE_93 , CODABAR , DATA_MATRIX , PDF_417 , AZTEC and many more.

I made a QR Generator application, when using the eagle version there is no problem, but after updating to Fenix, this extension can’t generate a QR Code. is there a solution?

[vknow360 (Sunny Gupta)]

Post an APK.

[sadid_al_Mannan (Zayada)]

I use sample from your project

the notification “QR Code Generate Successfully” appears, but the QR Code does not appear

[vknow360 (Sunny Gupta)]

That’s quite old version.
Update to latest version.

[sadid_al_Mannan (Zayada)]

Ok, ill try… thank you

[sadid_al_Mannan (Zayada)]

I’ve updated to the latest extension, but the QR Code still doesn’t appear

the notification “QR Code Generate Successfully” appears, but the QR Code does not appear

Similar problem here:

Someone help me out from this problem

After kodular Fenix 1.5.0 update i got a problem in image category. when i want to show image from my phone storage its not working. But its working in Kodular old version 1.4.0 this is screenrecord of my problem. [blocks (1)] and this is my block.

Probably you can prefix file:// before the file path after getting file path.

[sadid_al_Mannan (Zayada)]

Same result with this method

[vknow360 (Sunny Gupta)]

Strange, it is working here:

Image_Picker after picking image not showing

after updating kodular, image not showing [blocks (4)]

Can you try loading that file in WebViewer?

[sadid_al_Mannan (Zayada)]

I think the problem is not in the load picture method, but in generating the QR Code. Because after I generate it, a QR.png file appears in the gallery with an empty image

[vknow360 (Sunny Gupta)]

Maybe possible.
Can you post the newer APK then?

[sadid_al_Mannan (Zayada)]

This is the apk

cobaQR.apk (5.6 MB)

[vknow360 (Sunny Gupta)]

Yeah I can confirm the issue is somewhere.

[sadid_al_Mannan (Zayada)]

Maybe any solution?

Note:
Before updating to fenix, I used this extension, and it worked normally. But today I compile using fenix, it doesn’t work. It’s not only this extension that doesn’t work, but the QR Scanner (not the default scanner) can’t work either.
