本文介绍如何在华为U8860手机上开启Android系统的Log记录功能，以便于在使用真机进行应用调试时能够获取到调试信息。具体步骤包括通过特定代码进入测试菜单，设置Log开关并调整Log级别。

在我们使用真机进行Android应用调试时，无法获得调试信息，错误提示如下：Unable to open log device ‘/dev/log/main’: No such file or directory

这是因为我们的手机没有开起log记录，下面以华为U8860为例开启手机的log功能:

1、在拨号界面输入：*#*#2846579#*#* 进入测试菜单界面。

2、Project Menu–后台设置–LOG设置

3、LOG开关–LOG打开 LOG级别设置–VERBOSE

4、Dump&Log– 全部选中

5、重启手机

i2c-and-cross-gcc-and-qemu-mount-nfs qemu-mount-nfs 1. 服务端(ubuntu)配置 1.1 命令及说明 (1) 创建根目录和共享挂载点 sudo mkdir -p /nfs/zxxr (2) 将挂载目录绑定到共享挂载点 sudo mount --bind /home/ujnstu/zxxr/ /nfs/zxxr 其作用为ubuntu下的/nfs/zxxr和/home/ujnstu/zxxr与开发板下的文件/mnt(本文中)，这三个文件夹实现共享。.
