Same problem! I fix it by a step-by-step guide in which writer explains very well how to implement a barcode reader/encoder using zxing library. The difference from original manual is that he seems to use his version of library, modified in some point (as he shows in the article) that fixes the problem. Follow his instructions and download his zxing library. It works for me:
