 ===== NDK-provided function macros: =====
 这里定义了一些宏命令，使用方法：
-  $(call <function>)
+<code>
+$(call <function>)
+</code>
   * my-dir
 返回当前Android.mk目录路径
   * all-subdir-makefiles
 返回当前目录下（my-dir），及子目录下的Android.mk文件列表。
+  * this-makefile
+返回当前Makefile文件路径。
+  * parent-makefile
+Returns the path of the current Makefile (i.e. where the function is called)
+  * parent-makefile
+Returns the path of the parent Makefile in the inclusion tree,  i.e. the path of the Makefile that included the current one.
+Unordered List Item
+  * grand-parent-makefile
+    Guess what..
+===== Module-description variables =====
+定义一些变量，这些变量应该写在'include $(CLEAR_VARS)'和'include $(BUILD_XXXXX)'之间，之前说到的$(CLEAR_VARS)可以用来清除之前的一些变量。
+  * LOCAL_PATH
+提示当前文件的路径，必须定义在文件开头
+  LOCAL_PATH := $(call my-dir）
+这个变量不会被$(CLEAR_VARS)清空，所以每个Android.mk都需要定义一次这个变量，就算你定义了几个module,也就定义一次就行了。
+  * LOCAL_MODULE
+这是你定义的模块名字，名字必须唯一，且不能含有空格，必须定义在$(BUILD_XXXX)前面.
+  * LOCAL_SRC_FILES
+src文件列表，路径是相对于LOCAL_PATH
+  * LOCAL_CPP_EXTENSION
+可选变量用来定义C++文件后缀，'.cpp'
+<code>
+LOCAL_CPP_EXTENTION := .cxx
+</code>
+  * LOCAL_C_INCLUDES
+An optional list of paths, relative to the NDK *root* directory, which will be appended to the include search path when compiling    all sources (C, C++ and Assembly). For example:
+  LOCAL_C_INCLUDES := sources/foo
+Or even:
+  LOCAL_C_INCLUDES := $(LOCAL_PATH)/../foo
+These are placed before any corresponding inclusion flag in LOCAL_CFLAGS / LOCAL_CPPFLAG
+  * LOCAL_CFLAGS
+  * LOCAL_CXXFLAGS
+  * LOCAL_CPPFLAGS
+  * LOCAL_STATIC_LIBRARIES
+静态库模块列表（用BUILD_STATIC_LIBRARY生成的），用来链接到当前模块，只在动态共享库中会用到。
+  * LOCAL_SHARED_LIBRARIE
+运行是需要的，链接时需要的，还是看原来的说明吧，
+<code>
+ The list of shared libraries *modules* this module depends on at runtime.
+    This is necessary at link time and to embed the corresponding information
+    in the generated file.
+    Note that this does not append the listed modules to the build graph,
+    i.e. you should still add them to your application's required modules
+    in your Application.m
+</code>
