Is there any free OCR library for Android? [closed]

by

OCR can be pretty CPU intensive, you might want to reconsider doing it on a smart phone.

That aside, to my knowledge the popular OCR libraries are Aspire and Tesseract. Neither are straight up Java, so you’re not going to get a drop-in Android OCR library.

However, Tesseract is open source (GitHub hosted infact); so you can throw some time at porting the subset you need to Java. My understanding is its not insane C++, so depending on how badly you need OCR it might be worth the time.

So short answer: No.

Long answer: if you’re willing to work for it.
