使用mm命令遇到的问题

修改了framework中的文件，然后

 source build/envsetup.sh
 mm xxx/xxxx

出现错误：

find: `frameworks/base/docs/html-ndk': No such file or directory

#### make failed to build some targets (2 seconds) ####

发现是之前缺少命令。重新执行：

 source build/envsetup.sh  
 lunch xxx  
 cd xxx
 mm   
 make snod

会生成新的system.img。

比如修改frameworks/base/services下的文件：

 source build/envsetup.sh  
 lunch xxx  
 cd frameworks/base/services  
 mm  

回到根目录，然后：

make snod
