这里提供了一些代码，帮助你实现一些普通的编译任务。

一、编译一个简单的APK
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
 
# Tell it to build an APK
include $(BUILD_PACKAGE)
二、编译一个依赖某个.jar文件的APK
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)
三、编译一个用platform key签过名的APK
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)
四、编译一个用vendor key签名的APK
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)

五、添加一个prebuilt APK
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)
六、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)
七、Android.mk中的变量
下面列出了一些你在Android.mk文件中常见的变量，先看一下名字前缀：
1、LOCAL_：这类变量每个模块都要设置自己，用include $(CLEAR_VARS)可以清除这类变量，这类变量也是使用最多的。
2、PRIVATE_：这类变量是make-target-specific的变量。只有在编译某个模块时才会用到这类变量。在你从子模块返回时，这类变量不会改变。这个可以对我一下标准的make教程。
3、HOST_和TARGET_：这里包含了一些针对特定的host或target的目录和定义。不要在make文件中设置这类变量。
4、BUILD_和CLEAR_VARS：这类变量通常是一些预定义过的模板make文件的名字。比如CLEAR_VARS和BUILD_HOST_PACKAGE，通常执行某个具体功能。
5、编译系统不可以递归调用，因为所有的变量都是全局的。

Parameter	Description
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	In Android.mk files that include $(BUILD_PACKAGE) set this to the set of files you want built into your app. Usually: LOCAL_ASSET_FILES += $(call find-subdir-assets) 调用 include $(BUILD_PACKAGE) 时，会把这个属性中列出的文件编译到 app 中。
LOCAL_BUILT_MODULE_STEM
LOCAL_C_INCLUDES	Additional directories to instruct the C/C++ compilers to look for header files in. These paths are rooted at the top of the tree. Use LOCAL_PATH if you have subdirectories of your own that you want in the include paths. 如果想C／C＋＋编译器在更多的目录中搜索头文件的话，把这些附加的目录包含在这个属性中。如果这些目录中还有子目录的话，使用 LOCAL_PATH For example: LOCAL_C_INCLUDES += extlibs/zlib-1.2.3 LOCAL_C_INCLUDES += $(LOCAL_PATH)/src You should not add subdirectories of include to LOCAL_C_INCLUDES , instead you should reference those files in the #include statement with their subdirectories. 不要把子目录添加到这个属性中去，应该使用 #include 去包含子目录。 For example: #include <utils/KeyedVector.h> not #include <KeyedVector.h>
LOCAL_CC	If you want to use a different C compiler for this module, set LOCAL_CC to the path to the compiler. If LOCAL_CC is blank, the appropriate default compiler is used. 如果你想为当前模块使用一个不同的C编译器，就在这个属性中设置好路径
LOCAL_CERTIFICATE
LOCAL_CFLAGS	If you have additional flags to pass into the C or C++ compiler, add them here. 如果有一些标识需要传递给编译器的话，放在这个属性中。 For example: LOCAL_CFLAGS += -DLIBUTILS_NATIVE=1
LOCAL_CLASSPATH
LOCAL_COMPRESS_MODULE_SYMBOLS
LOCAL_COPY_HEADERS	The set of files to copy to the install include tree. You must also supply LOCAL_COPY_HEADERS_TO . This is going away because copying headers messes up the error messages, and may lead to people editing those headers instead of the correct ones. It also makes it easier to do bad layering in the system, which we want to avoid. We also aren't doing a C/C++ SDK, so there is no ultimate requirement to copy any headers. 由于这个属性常常引起一些问题，以后会被删除。
LOCAL_COPY_HEADERS_TO	The directory within "include" to copy the headers listed in LOCAL_COPY_HEADERS to. This is going away because copying headers messes up the error messages, and may lead to people editing those headers instead of the correct ones. It also makes it easier to do bad layering in the system, which we want to avoid. We also aren't doing a C/C++ SDK, so there is no ultimate requirement to copy any headers.
LOCAL_CPP_EXTENSION	If your C++ files end in something other than " .cpp ", you can specify the custom extension here. 如果你的C＋＋文件扩展名不是“ .cpp ”的话，把自定义的扩展名写在这里。 For example: LOCAL_CPP_EXTENSION := .cc Note that all C++ files for a given module must have the same extension; it is not currently possible to mix different extensions. 注意，一个模块中，所有的C＋＋文件必须有相同的扩展名。
LOCAL_CPPFLAGS	If you have additional flags to pass into only the C++ compiler, add them here. 你如果只想传递一些标志给C＋＋编译器，写在这里。 For example: LOCAL_CPPFLAGS += -ffriend-injection LOCAL_CPPFLAGS is guaranteed to be after LOCAL_CFLAGS on the compile line, so you can use it to override flags listed in LOCAL_CFLAGS
LOCAL_CXX	If you want to use a different C++ compiler for this module, set LOCAL_CXX to the path to the compiler. If LOCAL_CXX is blank, the appropriate default compiler is used. 如果想为当前模块使用一个不同的C＋＋编译器，把编译器的路径写在这里
LOCAL_DX_FLAGS
LOCAL_EXPORT_PACKAGE_RESOURCES
LOCAL_FORCE_STATIC_EXECUTABLE	If your executable should be linked statically, set LOCAL_FORCE_STATIC_EXECUTABLE:=true . There is a very short list of libraries that we have in static form (currently only libc). This is really only used for executables in /sbin on the root filesystem. 如果你的可执行文件需要静态链接的话，就把这个变量设置为true。只有很少的库需要静态链接，目前只是libc库。事实上，这种形式只用于/sbin目录下的可执行文件。
LOCAL_GENERATED_SOURCES	Files that you add to LOCAL_GENERATED_SOURCES will be automatically generated and then linked in when your module is built. See the Custom Tools template makefile for an example. 添加到这个属性中的文件会在编译模块时自动生成并链接，可以看一下例子子。
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	When linking Java apps and libraries, LOCAL_JAVA_LIBRARIES specifies which sets of java classes to include. Currently there are two of these: core and framework . In most cases, it will look like this: LOCAL_JAVA_LIBRARIES := core framework Note that setting LOCAL_JAVA_LIBRARIES is not necessary (and is not allowed) when building an APK with " include $(BUILD_PACKAGE) ". The appropriate libraries will be included automatically. 链接Java程序和Java库时，这个属性会标识出哪个Java库会被包含。当前只有两个， core 和 framework 。大部分情况下，会是这样的形式： LOCAL_JAVA_LIBRARIES := core framework 。注意，当使用" include $(BUILD_PACKAGE) "来编译APK时，这个属性不能设置。因为相应库会自动链接。
LOCAL_JAVA_RESOURCE_DIRS
LOCAL_JAVA_RESOURCE_FILES
LOCAL_JNI_SHARED_LIBRARIES
LOCAL_LDFLAGS	You can pass additional flags to the linker by setting LOCAL_LDFLAGS . Keep in mind that the order of parameters is very important to ld, so test whatever you do on all platforms. 通过这个属性，你可以向链接器传递一些会加的标识。一定要注意，参数的顺序对ld来说非常重要，多多测试。
LOCAL_LDLIBS	LOCAL_LDLIBS allows you to specify additional libraries that are not part of the build for your executable or library. Specify the libraries you want in -lxxx format; they're passed directly to the link line. However, keep in mind that there will be no dependency generated for these libraries. It's most useful in simulator builds where you want to use a library preinstalled on the host. The linker (ld) is a particularly fussy beast, so it's sometimes necessary to pass other flags here if you're doing something sneaky. 不管是编译可执行文件还是编译库，这个属性允许你添加一些附加库。需要注意的是，编译系统不会生成这些库的依赖关系。通常，这个属性会在编译模拟器时使用，你可能会使用一个已经安装在host上的库。 Some examples: LOCAL_LDLIBS += -lcurses -lpthread LOCAL_LDLIBS += -Wl,-z,origin
LOCAL_MODULE	LOCAL_MODULE is the name of what's supposed to be generated from your Android.mk. For exmample, for libkjs, the LOCAL_MODULE is "libkjs" (the build system adds the appropriate suffix -- .so .dylib .dll). For app modules, use LOCAL_PACKAGE_NAME instead of LOCAL_MODULE . 这个属性存放你要生成的模块名字。如果是app模块，使用 LOCAL_PACKAGE_NAME 属性。
LOCAL_MODULE_PATH	Instructs the build system to put the module somewhere other than what's normal for its type. If you override this, make sure you also set LOCAL_UNSTRIPPED_PATH if it's an executable or a shared library so the unstripped binary has somewhere to go. An error will occur if you forget to. 用新路径替换掉编译系统生成模块的默认存放路径。如果编译目标是一个可执行文件或者一个共享库，还必须设置 LOCAL_UNSTRIPPED_PATH 属性来保存unstripped二进制文件，如果没有设置的话，编译系统会报错。 See Putting modules elsewhere for more.
LOCAL_MODULE_STEM
LOCAL_MODULE_TAGS	Set LOCAL_MODULE_TAGS to any number of whitespace-separated tags. This variable controls what build flavors the package gets included in. 该属性的多个值之间以空格分隔。 For example: user : include this in user/userdebug builds eng : include this in eng builds tests : the target is a testing target and makes it available for tests optional : don't include this
LOCAL_NO_DEFAULT_COMPILER_FLAGS
LOCAL_NO_EMMA_COMPILE
LOCAL_NO_EMMA_INSTRUMENT
LOCAL_NO_STANDARD_LIBRARIES
LOCAL_OVERRIDES_PACKAGES
LOCAL_PACKAGE_NAME	LOCAL_PACKAGE_NAME is the name of an app. For example, Dialer, Contacts, etc. 属性值是要生成的app的名字。
LOCAL_POST_PROCESS_COMMAND	For host executables, you can specify a command to run on the module after it's been linked. You might have to go through some contortions to get variables right because of early or late variable evaluation: module := $(HOST_OUT_EXECUTABLES)/$(LOCAL_MODULE) LOCAL_POST_PROCESS_COMMAND := /Developer/Tools/Rez -d __DARWIN__ -t APPL/ -d __WXMAC__ -o $(module) Carbon.r
LOCAL_PREBUILT_EXECUTABLES	When including $(BUILD_PREBUILT) or $(BUILD_HOST_PREBUILT), set these to executables that you want copied. They're located automatically into the right bin directory. 使用$(BUILD_PREBUILT) 或$(BUILD_HOST_PREBUILT)时，这个属性设置为你想复制的可执行文件列表，它们会被自动定位。
LOCAL_PREBUILT_JAVA_LIBRARIES
LOCAL_PREBUILT_LIBS	When including $(BUILD_PREBUILT) or $(BUILD_HOST_PREBUILT), set these to libraries that you want copied. They're located automatically into the right lib directory. 使用$(BUILD_PREBUILT) 或$(BUILD_HOST_PREBUILT)时，这个属性设置为你想复制的库文件列表，它们会被自动定位。
LOCAL_PREBUILT_OBJ_FILES
LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES
LOCAL_PRELINK_MODULE
LOCAL_REQUIRED_MODULES	Set LOCAL_REQUIRED_MODULES to any number of whitespace-separated module names, like "libblah" or "Email". If this module is installed, all of the modules that it requires will be installed as well. This can be used to, e.g., ensure that necessary shared libraries or providers are installed when a given app is installed. 属性值是有空格分隔的一系列模块名字，如“libblah”或“Email”。如果当前编译的模块被安装，这个列表中所有的模块也会被安装。假如你需要安装一个app时，这种机制可以保证app依赖的共享库或者provider被安装。
LOCAL_RESOURCE_DIR
LOCAL_SDK_VERSION
LOCAL_SHARED_LIBRARIES	These are the libraries you directly link against. 编译时需要链接的库的列表。 You don't need to pass transitively included libraries. Specify the name without the suffix: LOCAL_SHARED_LIBRARIES := / libutils / libui / libaudio / libexpat / libsgl
LOCAL_SRC_FILES	The build system looks at LOCAL_SRC_FILES to know what source files to compile -- .cpp .c .y .l .java. For lex and yacc files, it knows how to correctly do the intermediate .h and .c/.cpp files automatically. If the files are in a subdirectory of the one containing the Android.mk, prefix them with the directory name: 需要编译的文件列表，如果某些文件在一个子目录中，而且这个子目录中也包含一个Android.mk，就像下面这样使用。 LOCAL_SRC_FILES := / file1.cpp / dir/file2.cpp
LOCAL_STATIC_JAVA_LIBRARIES
LOCAL_STATIC_LIBRARIES	These are the static libraries that you want to include in your module. Mostly, we use shared libraries, but there are a couple of places, like executables in sbin and host executables where we use static libraries instead. 编译模块时需要链接的静态库列表。大部分情况下，我们使用共享库，但链接sbin中的可执行文件和host上的可执行文件时，会使用静态库。 LOCAL_STATIC_LIBRARIES := / libutils / libtinyxml
LOCAL_UNINSTALLABLE_MODULE
LOCAL_UNSTRIPPED_PATH	Instructs the build system to put the unstripped version of the module somewhere other than what's normal for its type. Usually, you override this because you overrode LOCAL_MODULE_PATH for an executable or a shared library. If you overrode LOCAL_MODULE_PATH , but not LOCAL_UNSTRIPPED_PATH , an error will occur. 告诉编译系统把模块的unstripped版本放在某个地方。通常，你给 LOCAL_MODULE_PATH 赋值时才会给这个属性赋值。如果你给 LOCAL_MODULE_PATH 赋值，但不给这个属性赋值，系统会报错。 See Putting modules elsewhere for more.
LOCAL_WHOLE_STATIC_LIBRARIES	These are the static libraries that you want to include in your module without allowing the linker to remove dead code from them. This is mostly useful if you want to add a static library to a shared library and have the static library's content exposed from the shared library. 想把静态库包含在模块中，又不想链接器移除无用的代码时，使用这个属性。通常用于你想把一个静态库添加到共享库中，或者让静态库从共享库中暴露出来时。 LOCAL_WHOLE_STATIC_LIBRARIES := / libsqlite3_android
LOCAL_YACCFLAGS	Any flags to pass to invocations of yacc for your module. A known limitation here is that the flags will be the same for all invocations of YACC for your module. This can be fixed. If you ever need it to be, just ask. 调用yacc时传递的标记。注意，当前模块中所有的yacc调用都会传递这个标记。 LOCAL_YACCFLAGS := -p kjsyy
OVERRIDE_BUILT_MODULE_PATH
