Fixed it, I just skip checking CRC32 algorithm and its working very fine.

see In doInBackGround() you will find `if (-1 != entry.mCRC32)`, just remove it. – Mohammed Azharuddin Shaikh Jul 30 '12 at 10:17

It appears that CRC check fails when you use compression on your Zip file. You can use 7-Zip manager and set _Compression Level_ to _Store_ and CRC check will succeed. – Sam R. Oct 28 '12 at 12:39

I suspect you are having the same problem as this question. In brief, the sample code doesn't work for compressed zip files.
