Hi thanks for your response, first I was using the version 1.1 (built 2023-10-12) and it was working excellent also in kodular, but now with the last SDK34 update it makes the app crashes at launch.
Now with the version 1.2 of the extension it opens fine the first time, but second time I open the app after the install it crashes, with the logcat I provided.
I´m on Android 14. Samsung Galaxy S21+.
I will take a look at the issue this evening. By then, can you please test the extension in App Inventor and see if it works on your phone?
Great! Thank you, I tested the aia file of this post and it seems to work fine. It opens the app correct and do the ocr.
I was now testing the same .aia file on the companion in AppInventor, and I get this error:
Writable dex file '/data/user/0/edu.mit.appinventor.aicompanion3/cache/external_comps/xyz.kumaraswamy.textrecognition/assets/text-recognition.dex' is not allowed.
I think it is the same kind of error I get on Kodular about the file "text-recognition.dex", if that helps
Version 1.3Thank you @Mental_Magic

Blocks of Screen1 & Text Recognition Extension are not showing in Blocks Section.
Is your Blocks Toolkit in Project Properties set to Default ?
No! I was Selected it as Custom. However, Now I have solved my problem and successfully created my app but After Building it as App, It is not installing in my Android mobile and show the message "App Not Installed". Kindly give me full guideline to fix it and make it compatible for all android phones.

can you send me your recognition text from camera pls i need it im new here
There is an image where i want text recognition and scan the qr code. How do i do the both process from picking the same file or by clicking picture using camera component?
Please provide an example...with an explanation of what you want to do, referencing the image.
[mod edit image removed]
This image contains a certificate case number and a QR code. I want to extract the certificate case number from the text and the token number embedded in the QR code. There are hundreds of such certificates. To fill a form, both the certificate case number and the token number are required. I have already created two separate apps—one for scanning the QR code and another for extracting the certificate case number. However, I want both processes to be completed in a single app by simply capturing a photo using the camera.
OK, I removed that image as I am sure it breaches someone's confidentiality. For others the image contained text and a qr code.
@vknow360 's qr code extension can read qr codes in an image, may be that will help ?
Please show your relevant blocks
Are you cropping the qrcode to a second image ?
