问题
Am using OCR as a module in a project that am doing. After digging in deep for a week i thought that i should run a test application on eclipse just to see how accurately it works. i found tess-two a fork of tesseract as a support to my OCR. i downloaded tess-two from:
https://github.com/rmtheis/tess-two/downloads
I was all set i imported tess-two into my eclipse. I did set my eclipse for handling and building projects involving native code. I did build tess-two successfully after solving 1 or 2 build path errors. DONE!
Then i found a simple OCR application which was using the same tess-two. i download it from:
https://github.com/GautamGupta/Simple-Android-OCR
I imported this project into my workspace. Corrected the build path i included tess-two as a supporting project in the build path. When i successfully build the two projects and run it on my target device the application runs successfully. when i run the camera with the button the camera opens but when i save the picture so that the ocr runs on it i get an exception:
could not find class 'com.googlecode.tesseract.android.TessBaseAPI' referenced from method com.datumdroid.android.ocr.simple.SimpleAndroidOCRActicity.picturetaken'
This was the exception generated by the logcat on eclipse. Any idea how can i deal and remove this exception?? Tess-two was android target-8 and simple ocr application was target-10.

Hope this helps
回答2:
make sure you marked tess-two as a library in the properties then right click your simple ocr and in the properties add tess two library and apply
