调用相机拍照，解决拍照时候内存溢出溢出的问题

废话少说，上代码

 1 private static int CARMER_REQUEST_CODE = 1;  
 2     private String filedirName = "sencondIDCard";  
 3     private String picFileName = "";

12         if(!dir.exists()){  
13             dir.mkdirs();  
14         }  
15   
16         Date date = null;   
17         SimpleDateFormat format = new SimpleDateFormat("yyyyMMddHHmmss");// 获取当前时间，进一步转化为字符串   
18         date = new Date();   
19         picFileName = format.format(date) + ".jpg";   
20         picFile = new File(dir,picFileName);
