안드로이드 FTPClient 다운로드 업로드시 얼만큼 진행되었는지 퍼센트로 표시하는법

    private void fileDownloadtest(final String strPath, final String strItem, final int i) {
            VsrcFilePath = strPath;
            VdesFilePath = FileUtil.FTPCLINET_LOCAL_DOWNLOAD + strItem;
            mHandler.sendEmptyMessageDelayed(Percent,3000);
        Thread mThread = new Thread(new Runnable() {
            
            @Override
            public void run() {
                try {
                    
                    boolean res = FTPManager.getInstance().ftpDownload(strPath + strItem,                     FileUtil.FTPCLINET_LOCAL_DOWNLOAD + strItem, i); //다운로드 하는곳

 

Thread를 써서  다운로드 받으면서 핸드러 쪽에서 퍼센트를 3초에 한번씩 출력하게 만들고 싶은데

핸들러에서 UpDownPercent2이 함수를 호출해서 실행하는데

100퍼센트가 되기전에 불러오면 오류가 나고 100퍼센트 되고나서 불러오면 100퍼센트라고 잘 나오는데

어떻게 해야 중간에 값들을 불러올수 있을까요?

    String UpDownPercent2(String srcFilePath, String desFilePath, int downPos) {
        // TODO Auto-generated method stub
        FTPFile[] Fa = null;
        
            // 퍼센트 용량 불러오기
            try {
                Fa = mFTPClient.listFiles(srcFilePath);
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            int a2 = (int) Fa[downPos-1].getSize();
            String b = FileUtil.txtFileImformation(desFilePath);
            int b2 = (int) Long.parseLong(b);
            double percent = (double)((double)b2/(double)a2) * 100;
                //Float percent = (float) ((a2/b2)*100);
            String dispPattern = "0.##";
            DecimalFormat form = new DecimalFormat(dispPattern);
            percent = (int)Float.parseFloat(form.format(percent));
            String per = String.valueOf(percent);
            //this.totalBytesTransferred = totalBytesTransferred;
                    if(a2==b2)
                    {
                        PercentEnd = true;
                    }
                    return per;
                    
    }
