I'm looking for a Java OCR that runs on Android, however Asprise doesn't seem to be a platform independent OCR. is there any opensource/free Java OCR I can use for android application development?

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.
ANother option could be to post the image to a webapp (possibly at a later moment), and have it OCR-processed there without the C++ -> Java port issues and possibly clogging the mobile CPU.
