Android Question Looking for working Sample B4A 10.7 Text recognisition

[Jan Vrielink]

I would like to incorporate some text recognition functionality in my app.
But all libraries / examples found in this forum do not work with my b4a 10.7 installation.
Does anyone have an example that works on b4a 10.7?

What examples don't work ?

I think all examples:
The following projects i have tried:

Works without a problem using Java 11 and B4A 10.7 (targetSDKversion = 29)

thank you for your quick response. Something must be wrong with my development environment.
By the way; b4aAndroidTextRecognition compiles and runs also succesfully in my environment, but no text is detected (in the events of your example).
No matter what text size the text is.
I have tried on another pc with clean(er) install; but also no recognition
Tomorrow i will try again.

Check the B4A log when you have clicked on "Grab Text" - also click on Connect in the Logs tab of the IDE. The text will be in the B4A log

Your question points me to the right direction:
I did not have a 'grab text'-button because i downloaded the sample at the start of the thread. I thought this was the last version (edited 15 aug), but then i saw an newer project 1.01 in de discussion. When i tried that one, the grab text button works !
The atr1_text_scanned_blocks/text_scanned_lines-events still are not triggered also in this sample also, but that is not a problem because the 'grab text'-button-code is enough for me. I am satisfied with this great library; the problems with the other text recognition samples were mostly compiling problems, so i do not need a solution for that.
Thank you Johan, also i have used your barcode project; you did a great job.
Still I decided to switch to https://www.b4x.com/android/forum/t...er-that-is-100-embedded-in-b4a.63764/#content because it scans a CODE_128 faster.
Thanks a lot
