用法：把上面的代码复制一下，把它挂到游戏场景中的任意一个物体即可，发布apk就可以进行查看信息
这样就可以输出你的错误信息和你的调试信息。非常方便的工具可以提高开发效率

//每次启动客户端删除之前保存的Log
if (System.IO.File.Exists(outpath))
{

}
//在这里做一个Log的监听
//转载的原文中是用Application.RegisterLogCallback(HandleLog);但是这个方法在unity5.0版本已经废弃不用了
Application.logMessageReceived += HandleLog;
//一个输出
Debug.Log("chenj_freedom~~~~~");
}

生成的log文件在什么位置？
当项目编译的时候，Player Settings中的Write Acess选择“Internal Only”，那么log文件在data/data/包名/Files/outLog.txt（需要root权限）；如果Write Acess选择“External (SDCard)”，那么log文件在SDCard/Android/包名/Files/outLog.txt，推荐后者。
