Building a particular module in the android source code

Question

I am working on an android source code which I have downloaded from source.android.com.

After a full build I went through this site http://elinux.org/Android_Build_S

Answer 1

Here are fuller descriptions of mm, mmm, and other convenient functions provided by sourcing the build/envsetup.sh file:

Invoke . build/envsetup.sh from your shell to add the following functions to your environment:

   lunch:   lunch -
   tapas:   tapas [  ...] [arm|x86|mips|armv5] [eng|userdebug|user]
   croot:   Changes directory to the top of the tree.
   m:       Makes from the top of the tree.
   mm:      Builds all of the modules in the current directory, but not their dependencies.
   mmm:     Builds all of the modules in the supplied directories, but not their dependencies.
            To limit the modules being built use the syntax: mmm dir/:target1,target2.
   mma:     Builds all of the modules in the current directory, and their dependencies.
   mmma:    Builds all of the modules in the supplied directories, and their dependencies.
   cgrep:   Greps on all local C/C++ files.
   jgrep:   Greps on all local Java files.
   resgrep: Greps on all local res/*.xml files.
   godir:   Go to the directory containing a file.

Plese check build/envsetup.sh file's comments to see full list of functions.
