D:\xxx\sdk是我的sdk路径，于是到此目录下查看日志文件，描述如下：

错误信息说目录是只读的，但目录只有C:/Users/Lison Liou/.android，后面就没有了，于是干脆给目录加上Everyone用户的Full Control权限，结果还是不行。

后来在StackOverFlow上找到答案，Android DDMS (Monitor) does not start if user profile contains a space in it，说DDMS不会启动如果用户名包含空格，我的用户名的确包含空格，但是之前也是好用的，不解。

解决方法如下：以管理员身份运行cmd（必须），输入如下：

1
2
3
cd c:/users

mklink /d "Lison%20Liou" "Lison Liou"

将带空格的用户与正常用户名建立链接（软连接或者硬链接就不知道了），Lison Liou是我的计算机用户，成功后会提示：

symbolic link created for Lison%20Liou <<===>> Lison Liou

搞定。
