public void writeToFile(String filename, byte[] pData){
        if(pData == null){
            return;
        }
        int lByteArraySize = pData.length;
        System.out.println(filename);
        try{
            File lOutFile = new File("C:/madev/"+filename+".jpg");
            FileOutputStream lFileOutputStream = new FileOutputStream(lOutFile);
            lFileOutputStream.write(pData);
            lFileOutputStream.close();
        }catch(Throwable e){
            e.printStackTrace(System.out);
        }
