Function From calling to extract file

public void extract()
{

            String packageName = getApplicationContext().getPackageName();

            File root = Environment.getExternalStorageDirectory();
            File expPath = new File(root.toString() + "/Android/obb/" + packageName);

            if (expPath.exists()) {
                String strMainPath = null;
                try {
                    strMainPath = expPath + File.separator + "main."
                        + getPackageManager().getPackageInfo(
                                    getPackageName(), 0).versionCode + "."
                            + packageName + ".obb";


                Log.e("Extract File path", "===>"+strMainPath);

                File f=new File(strMainPath);
                if(f.exists()){
                    Log.e("Extract From File path", "===> not exist");
                }
                else
                {
                    Log.e("Extract From File path", "===> exist");
                }

                flag = extractZip(strMainPath,Environment.getExternalStorageDirectory()+"/"+Constant.FOLDERNAME);

                Log.e("After Extract Zip", "===>"+flag);
                } catch (NameNotFoundException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }

            }

Try this:-

After very struggle finally i found a solution.I was ziping the whole folder with subfolder also by right click in ubuntu12.04.

But After that i tried select all images/files then zip them to new folder. By the above code i was able to extracted all the files successfully.

Thanks......
