注意事项：
- 建好的文件有时候看不到，需要重启手机或者是调用 MediaScannerConnection.scanFile 方法。scanFile 方法在测试三星机型上有时候没有找到文件夹，需要重新启动手机，当其有文件夹就可以找到该文件了。
- 输出日期时间 需要HH,如果为 hh，则下午时间和早上时间区分不开
- 通过下面方法将异常捕获在 public void uncaughtException(Thread thread, Throwable ex) 中处理
//设置该CrashHandler为程序的默认处理器
Thread.setDefaultUncaughtExceptionHandler(this); - 考虑文件拼接，printwrite 不直接输入文件内容，其会覆盖之前内容，输出编码格式为utf-8,需要OutputStreamWriter 转码。
- addUserInfo 可以自己定义需要传递的用户信息。
- 服务器上传 可以考虑与后台配合完成
