利用mm命令编译Android模块 .

在Android开发过程中，当我们只需要编译某个修改过的模块时，使用mm命令可以使你不用编译整个Android项目，而只需单独编译该模块即可，这样速度是不是很快呢？具体的步骤如下：

1. 在Android源代码目录下:

cd mydroid
source build/envsetup.sh

cd mydroid source build/envsetup.sh

也可以将source ~/mydroid/build/envsetup.sh放到~/.bashrc中，这样每次打开shell时就会自动运行该脚本。

2. 在shell中使用help命令查看可以运行的命令

# help
Invoke ". build/envsetup.sh" from your shell to add the following functions to your environment:
- 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.
- mmm:     Builds all of the modules in the supplied directories.
- 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.

Look at the source to view more functions. The complete list is:
add_lunch_combo cgrep check_product check_variant choosecombo chooseproduct choosetype choosevariant cproj croot findmakefile gdbclient get_abs_build_var getbugreports get_build_var getprebuilt gettop godir help isviewserverstarted jgrep lunch m mm mmm pid printconfig print_lunch_menu resgrep runhat runtest set_java_home setpaths set_sequence_number set_stuff_for_environment settitle smoketest startviewserver stopviewserver systemstack tapas tracedmdump

可以看到mm命令，意思是编译当前文件夹下的所有模块。

3. 接下来的事情将变得很简单，只需来到需要编译的模块文件夹下，运行mm命令即可，当然我们也可以用mmm命令，如mmm external/jpeg/，和在external/jpeg/目录下运行mm命令具有同样的效果。
