   /** 
     * 保存文件 
     * @param bm 
     * @param fileName 
     * @throws IOException 
     */  
    public void saveFile(Bitmap bm, String fileName) throws IOException { 
     String path = getSDPath() +"/revoeye/";     
        File dirFile = new File(path);  
        if(!dirFile.exists()){  
            dirFile.mkdir();  
        }  
        File myCaptureFile = new File(path + fileName);  
        BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(myCaptureFile));  
        bm.compress(Bitmap.CompressFormat.JPEG, 80, bos);  
        bos.flush();  
        bos.close();  
    }
