Crash when returning result from image about easy-ocr-scanner-android HOT 14 OPEN

From the original post...

couldn't find "libpngt.so"

I ran into this before. In Android studio, right click the module, select "Open Module Settings", click the "Dependencies" tab, remove the "easy_ocr_library", click "OK". Then right click the "easy_ocr_library" in your project, select "Open Module Settings" and remove the "easy_ocr_library" module by using the red "-". Close Android Studio then go to your folder that contains the "easy_ocr_library" and delete the whole "easy_ocr_library" folder and rebuild it from new.

This doesn't solve the core problem but gets you back to where you were I've found.

Changing the dependency of easy_ocr_library module should solve the problem:

1. Delete tess-two module
2. Add a maven dependencycom.rmtheis:tess-two:6.1.1

from easy-ocr-scanner-android.

I had exactly the same issue. Is there any way to solve this? It happens right after you take the picture. It tries to scan for a while, then crashes. That's my first time working with an OCR API, and I must say your code helped me a lot to have the basis. If you could tell how to go through this, it would be great. Thanks!

I am having my exams. Will look into this after exams. If you write steps to reproduce it, that would be great.

from easy-ocr-scanner-android.

Thanks for your reply. I repeated all the steps carefully to run the app, and for some reason it works now. One thing I dont now how to deal with is the quality of the recognition and also the time spent, very long sometimes, and not returning a satisfactory result after it. Do you know how I could improve this?

Thanks again.

from easy-ocr-scanner-android.

@gsiqueira Time spent depends on the quality of the image. Large image size means more time needed to process it.

from easy-ocr-scanner-android.

Yes, I tried some things to solve this problem, I reduced the size (640x460 and smaller) of the image taken, tried to binarize it, turn flash on, to improve brightness, but I still get the same result, which takes about one and two minutes to finish the process. The image I used to test has just 10 short lines, is this normal?

I was looking at the code here, and I found the following:

It is strange, because android studio builds the app and it works. I am just showing you this because I don't know if it has something to do with my problem.

Below you find the image I used and the best result I took. Thank you a lot for your attention in my problem.

Well the accuracy of OCR is not 100% accurate, at least this is the case for the ones those are open sourced.

Hi,

I get the same error, while running in LG G3:

@gsiqueira
Do you have any ideas what was the root cause in your case?

from easy-ocr-scanner-android.

Hi all, seems studio removes build directory, i fixed the problem by: git checkout easy_ocr_library/libs/tess-two/build/* Check that needed files not deleted by git status.

Still not working for me...!! Cannot resolve ImageProcessingThread
