android编译系统的makefile文件Android.mk写法如下

(1)Android.mk文件首先需要指定LOCAL_PATH变量，用于查找源文件。由于一般情况下
Android.mk和需要编译的源文件在同一目录下，所以定义成如下形式：
LOCAL_PATH:=$(call my-dir)
上面的语句的意思是将LOCAL_PATH变量定义成本文件所在目录路径。

(2)Android.mk中可以定义多个编译模块，每个编译模块都是以include$(CLEAR_VARS)开始
以include $(BUILD_XXX)结束。
include $(CLEAR_VARS)
CLEAR_VARS由编译系统提供，指定让GNUMAKEFILE为你清除除LOCAL_PATH以外的所有LOCAL_XXX变量，
如LOCAL_MODULE，LOCAL_SRC_FILES，LOCAL_SHARED_LIBRARIES，LOCAL_STATIC_LIBRARIES等。
include $(BUILD_STATIC_LIBRARY)表示编译成静态库
include $(BUILD_SHARED_LIBRARY)表示编译成动态库。
include $(BUILD_EXECUTABLE)表示编译成可执行程序

(3)举例如下(frameworks/base/libs/audioflinger/Android.mk)：

LOCAL_PATH:= $(call my-dir)
 include $(CLEAR_VARS)  模块一
 ifeq ($(AUDIO_POLICY_TEST),true)
   ENABLE_AUDIO_DUMP := true
 endif
 LOCAL_SRC_FILES:= \
    AudioHardwareGeneric.cpp \
    AudioHardwareStub.cpp \
    AudioHardwareInterface.cpp
 ifeq ($(ENABLE_AUDIO_DUMP),true)
   LOCAL_SRC_FILES += AudioDumpInterface.cpp
   LOCAL_CFLAGS += -DENABLE_AUDIO_DUMP
 endif
 LOCAL_SHARED_LIBRARIES := \
     libcutils\
     libutils\
     libbinder\
     libmedia\
    libhardware_legacy
 ifeq ($(strip $(BOARD_USES_GENERIC_AUDIO)),true)
   LOCAL_CFLAGS += -DGENERIC_AUDIO
 endif
 LOCAL_MODULE:= libaudiointerface
 ifeq ($(BOARD_HAVE_BLUETOOTH),true)
   LOCAL_SRC_FILES += A2dpAudioInterface.cpp
   LOCAL_SHARED_LIBRARIES += liba2dp
   LOCAL_CFLAGS += -DWITH_BLUETOOTH-DWITH_A2DP
   LOCAL_C_INCLUDES += $(call include-path-for,bluez)
 endif
 include $(BUILD_STATIC_LIBRARY)  模块一编译成静态库
 include $(CLEAR_VARS)  模块二
 LOCAL_SRC_FILES:=              \
    AudioPolicyManagerBase.cpp
 LOCAL_SHARED_LIBRARIES := \
     libcutils\
     libutils\
    libmedia
 ifeq ($(TARGET_SIMULATOR),true)
  LOCAL_LDLIBS += -ldl
 else
  LOCAL_SHARED_LIBRARIES += libdl
 endif
 LOCAL_MODULE:= libaudiopolicybase
 ifeq ($(BOARD_HAVE_BLUETOOTH),true)
   LOCAL_CFLAGS += -DWITH_A2DP
 endif
 ifeq ($(AUDIO_POLICY_TEST),true)
   LOCAL_CFLAGS += -DAUDIO_POLICY_TEST
 endif
 include $(BUILD_STATIC_LIBRARY) 模块二编译成静态库
 include $(CLEAR_VARS) 模块三
 LOCAL_SRC_FILES:=              \
    AudioFlinger.cpp           \
    AudioMixer.cpp.arm         \
    AudioResampler.cpp.arm     \
    AudioResamplerSinc.cpp.arm  \
    AudioResamplerCubic.cpp.arm \
    AudioPolicyService.cpp
 LOCAL_SHARED_LIBRARIES := \
     libcutils\
     libutils\
     libbinder\
     libmedia\
    libhardware_legacy
 ifeq ($(strip $(BOARD_USES_GENERIC_AUDIO)),true)
   LOCAL_STATIC_LIBRARIES += libaudiointerfacelibaudiopolicybase
   LOCAL_CFLAGS += -DGENERIC_AUDIO
 else
   LOCAL_SHARED_LIBRARIES += libaudiolibaudiopolicy
 endif
 ifeq ($(TARGET_SIMULATOR),true)
  LOCAL_LDLIBS += -ldl
 else
  LOCAL_SHARED_LIBRARIES += libdl
 endif
 LOCAL_MODULE:= libaudioflinger
 ifeq ($(BOARD_HAVE_BLUETOOTH),true)
   LOCAL_CFLAGS += -DWITH_BLUETOOTH-DWITH_A2DP
   LOCAL_SHARED_LIBRARIES += liba2dp
 endif
 ifeq ($(AUDIO_POLICY_TEST),true)
   LOCAL_CFLAGS += -DAUDIO_POLICY_TEST
 endif
 ifeq ($(TARGET_SIMULATOR),true)
     ifeq($(HOST_OS),linux)
        LOCAL_LDLIBS += -lrt -lpthread
     endif
 endif
 ifeq ($(BOARD_USE_LVMX),true)
     LOCAL_CFLAGS+= -DLVMX
    LOCAL_C_INCLUDES += vendor/nxp
    LOCAL_STATIC_LIBRARIES += liblifevibes
    LOCAL_SHARED_LIBRARIES += liblvmxservice
 #   LOCAL_SHARED_LIBRARIES += liblvmxipc
 endif
 include $(BUILD_SHARED_LIBRARY) 模块三编译成动态库

(4)编译一个应用程序(APK)

LOCAL_PATH := $(call my-dir)
   include $(CLEAR_VARS)
   
   # Build all java files in the javasubdirectory-->直译（建立在java子目录中的所有Java文件）
   LOCAL_SRC_FILES := $(callall-subdir-java-files)
   
   # Name of the APK tobuild-->直译（创建APK的名称）
   LOCAL_PACKAGE_NAME := LocalPackage
   
   # Tell it to build anAPK-->直译（告诉它来建立一个APK）

(5)编译一个依赖于静态Java库(static.jar)的应用程序

LOCAL_PATH := $(call my-dir)
   include $(CLEAR_VARS)
   
   # List of static libraries to include in thepackage
   LOCAL_STATIC_JAVA_LIBRARIES :=static-library
   
   # Build all java files in the javasubdirectory
   LOCAL_SRC_FILES := $(callall-subdir-java-files)
   
   # Name of the APK to build
   LOCAL_PACKAGE_NAME := LocalPackage
   
   # Tell it to build an APK

(6)编译一个需要用平台的key签名的应用程序

LOCAL_PATH := $(call my-dir)
   include $(CLEAR_VARS)
   
   # Build all java files in the javasubdirectory
   LOCAL_SRC_FILES := $(callall-subdir-java-files)
   
   # Name of the APK to build
   LOCAL_PACKAGE_NAME := LocalPackage
   
   LOCAL_CERTIFICATE := platform
   
   # Tell it to build an APK

(7)编译一个需要用特定key前面的应用程序

LOCAL_PATH := $(call my-dir)
   include $(CLEAR_VARS)
   
   # Build all java files in the javasubdirectory
   LOCAL_SRC_FILES := $(callall-subdir-java-files)
   
   # Name of the APK to build
   LOCAL_PACKAGE_NAME := LocalPackage
   
   LOCAL_CERTIFICATE :=vendor/example/certs/app
   
   # Tell it to build an APK

(8)添加一个预编译应用程序

LOCAL_PATH := $(call my-dir)
   include $(CLEAR_VARS)
   
   # Module name should match apk name to beinstalled.
   LOCAL_MODULE := LocalModuleName
   LOCAL_SRC_FILES := $(LOCAL_MODULE).apk
   LOCAL_MODULE_CLASS := APPS
   LOCAL_MODULE_SUFFIX :=$(COMMON_ANDROID_PACKAGE_SUFFIX)

(9)添加一个静态JAVA库

LOCAL_PATH := $(call my-dir)
   include $(CLEAR_VARS)
   
   # Build all java files in the javasubdirectory
   LOCAL_SRC_FILES := $(callall-subdir-java-files)
   
   # Any libraries that this library dependson
   LOCAL_JAVA_LIBRARIES :=android.test.runner
   
   # The name of the jar file to create
   LOCAL_MODULE := sample
   
   # Build a static jar file.

(10)Android.mk的编译模块中间可以定义相关的编译内容，也就是指定相关的变量如下：

LOCAL_AAPT_FLAGS
LOCAL_ACP_UNAVAILABLE 
LOCAL_ADDITIONAL_JAVA_DIR
  
 LOCAL_AIDL_INCLUDES LOCAL_ALLOW_UNDEFINED_SYMBOLS 
LOCAL_ARM_MODE 
LOCAL_ASFLAGS 
LOCAL_ASSET_DIR 
LOCAL_ASSET_FILES在Android.mk文件中编译应用程序(BUILD_PACKAGE)时设置此变量，表示资源文件，
                  通常会定义成LOCAL_ASSET_FILES += $(call find-subdir-assets)
  
 LOCAL_BUILT_MODULE_STEM 
 LOCAL_C_INCLUDES 额外的C/C++编译头文件路径，用LOCAL_PATH表示本文件所在目录
                 举例如下：
                 LOCAL_C_INCLUDES += extlibs/zlib-1.2.3
                 LOCAL_C_INCLUDES += $(LOCAL_PATH)/src
  
 LOCAL_CC 指定C编译器LOCAL_CERTIFICATE 
LOCAL_CFLAGS 为C/C++编译器定义额外的标志(如宏定义)，举例：LOCAL_CFLAGS +=-DLIBUTILS_NATIVE=1
  
 LOCAL_CLASSPATH LOCAL_COMPRESS_MODULE_SYMBOLS 
LOCAL_COPY_HEADERSinstall应用程序时需要复制的头文件，必须同时定义LOCAL_COPY_HEADERS_TO
  
 LOCAL_COPY_HEADERS_TO install应用程序时复制头文件的目的路径LOCAL_CPP_EXTENSION如果你的C++文件不是以cpp为文件后缀，你可以通过LOCAL_CPP_EXTENSION指定C++文件后缀名
                    如：LOCAL_CPP_EXTENSION := .cc
                    注意统一模块中C++文件后缀必须保持一致。LOCAL_CPPFLAGS 传递额外的标志给C++编译器，如：LOCAL_CPPFLAGS +=-ffriend-injection
LOCAL_CXX 指定C++编译器
  
 LOCAL_DX_FLAGSLOCAL_EXPORT_PACKAGE_RESOURCES
LOCAL_FORCE_STATIC_EXECUTABLE如果编译的可执行程序要进行静态链接(执行时不依赖于任何动态库)，则设置LOCAL_FORCE_STATIC_EXECUTABLE:=true
                              目前只有libc有静态库形式，这个只有文件系统中/sbin目录下的应用程序会用到，这个目录下的应用程序在运行时通常
                              文件系统的其它部分还没有加载，所以必须进行静态链接。
  
 LOCAL_GENERATED_SOURCES
  
 LOCAL_INSTRUMENTATION_FORLOCAL_INSTRUMENTATION_FOR_PACKAGE_NAME
LOCAL_INTERMEDIATE_SOURCES
LOCAL_INTERMEDIATE_TARGETS
LOCAL_IS_HOST_MODULE
LOCAL_JAR_MANIFEST
LOCAL_JARJAR_RULES
LOCAL_JAVA_LIBRARIES编译java应用程序和库的时候指定包含的java类库，目前有core和framework两种
                     多数情况下定义成：LOCAL_JAVA_LIBRARIES := core framework
                     注意LOCAL_JAVA_LIBRARIES不是必须的，而且编译APK时不允许定义(系统会自动添加)
  
 LOCAL_JAVA_RESOURCE_DIRS LOCAL_JAVA_RESOURCE_FILES 
LOCAL_JNI_SHARED_LIBRARIES 
LOCAL_LDFLAGS 传递额外的参数给连接器(务必注意参数的顺序)
  
 LOCAL_LDLIBS 为可执行程序或者库的编译指定额外的库，指定库以"-lxxx"格式，举例：
             LOCAL_LDLIBS += -lcurses -lpthread
             LOCAL_LDLIBS += -Wl,-z,origin
  
 LOCAL_MODULE生成的模块的名称(注意应用程序名称用LOCAL_PACKAGE_NAME而不是LOCAL_MODULE)LOCAL_MODULE_PATH 生成模块的路径
  
 LOCAL_MODULE_STEM
  
 LOCAL_MODULE_TAGS 生成模块的标记
  
 LOCAL_NO_DEFAULT_COMPILER_FLAGS LOCAL_NO_EMMA_COMPILE 
LOCAL_NO_EMMA_INSTRUMENT 
LOCAL_NO_STANDARD_LIBRARIES 
LOCAL_OVERRIDES_PACKAGES 
LOCAL_PACKAGE_NAME APK应用程序的名称 
LOCAL_POST_PROCESS_COMMAND
  
 LOCAL_PREBUILT_EXECUTABLES 预编译including$(BUILD_PREBUILT)或者$(BUILD_HOST_PREBUILT)时所用,指定需要复制的可执行文件LOCAL_PREBUILT_JAVA_LIBRARIES 
LOCAL_PREBUILT_LIBS 预编译including$(BUILD_PREBUILT)或者$(BUILD_HOST_PREBUILT)时所用, 指定需要复制的库.
LOCAL_PREBUILT_OBJ_FILES 
LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES 
  
 LOCAL_PRELINK_MODULE 是否需要预连接处理(默认需要，用来做动态库优化)LOCAL_REQUIRED_MODULES 指定模块运行所依赖的模块(模块安装时将会同步安装它所依赖的模块)
  
 LOCAL_RESOURCE_DIRLOCAL_SDK_VERSION
LOCAL_SHARED_LIBRARIES 可链接动态库
  
 LOCAL_SRC_FILES 编译源文件 LOCAL_STATIC_JAVA_LIBRARIES 
LOCAL_STATIC_LIBRARIES 可链接静态库
  
 LOCAL_UNINSTALLABLE_MODULE LOCAL_UNSTRIPPED_PATH
  
 LOCAL_WHOLE_STATIC_LIBRARIES指定模块所需要载入的完整静态库(这些精通库在链接是不允许链接器删除其中无用的代码)
  
 LOCAL_YACCFLAGS
  
 OVERRIDE_BUILT_MODULE_PATH
