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GNU MAKEFILE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 $(BOARD\_USES\_GENERIC\_AUDIO)),true)  
  LOCAL\_STATIC\_LIBRARIES += libaudiointerface libaudiopolicybase  
  LOCAL\_CFLAGS += -DGENERIC\_AUDIO  
else  
  LOCAL\_SHARED\_LIBRARIES += libaudio libaudiopolicy  
endif  
ifeq ($(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 java subdirectory-->直译（建立在java子目录中的所有Java文件）  
  LOCAL\_SRC\_FILES := $(call all-subdir-java-files)  
    
  \# Name of the APK to build-->直译（创建APK的名称）  
  LOCAL\_PACKAGE\_NAME := LocalPackage  
    
  \# Tell it to build an APK-->直译（告诉它来建立一个APK）  
  include $(BUILD\_PACKAGE)

(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 the package  
  LOCAL\_STATIC\_JAVA\_LIBRARIES := static-library  
    
  \# Build all java files in the java subdirectory  
  LOCAL\_SRC\_FILES := $(call all-subdir-java-files)  
    
  \# Name of the APK to build  
  LOCAL\_PACKAGE\_NAME := LocalPackage  
    
  \# Tell it to build an APK  
  include $(BUILD\_PACKAGE)

(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 java subdirectory  
  LOCAL\_SRC\_FILES := $(call all-subdir-java-files)  
    
  \# Name of the APK to build  
  LOCAL\_PACKAGE\_NAME := LocalPackage  
    
  LOCAL\_CERTIFICATE := platform  
    
  \# Tell it to build an APK  
  include $(BUILD\_PACKAGE)

(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 java subdirectory  
  LOCAL\_SRC\_FILES := $(call all-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  
  include $(BUILD\_PACKAGE)

(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 be installed.  
  LOCAL\_MODULE := LocalModuleName  
  LOCAL\_SRC\_FILES := $(LOCAL\_MODULE).apk  
  LOCAL\_MODULE\_CLASS := APPS  
  LOCAL\_MODULE\_SUFFIX := $(COMMON\_ANDROID\_PACKAGE\_SUFFIX)  
    
  include $(BUILD\_PREBUILT)

(9)添加一个静态JAVA库  
  LOCAL\_PATH := $(call my-dir)  
  include $(CLEAR\_VARS)  
    
  \# Build all java files in the java subdirectory  
  LOCAL\_SRC\_FILES := $(call all-subdir-java-files)  
    
  \# Any libraries that this library depends on  
  LOCAL\_JAVA\_LIBRARIES := android.test.runner  
    
  \# The name of the jar file to create  
  LOCAL\_MODULE := sample  
    
  \# Build a static jar file.  
  include $(BUILD\_STATIC\_JAVA\_LIBRARY)

(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  签名认证

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\_HEADERS install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\_FLAGS

LOCAL\_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\_FOR

LOCAL\_INSTRUMENTATION\_FOR\_PACKAGE\_NAME

LOCAL\_INTERMEDIATE\_SOURCES

LOCAL\_INTERMEDIATE\_TARGETS

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)
