android编译系统的makefile文件Android.mk写法如下
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_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_DIR
LOCAL_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
