文章标签 android 生成文件 android include build java 文章分类 Android 移动开发

(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)：

java代码：

1. LOCAL_PATH:= $(call my-dir)
2. include $(CLEAR_VARS) 模块一
3. ifeq ($(AUDIO_POLICY_TEST),true)
4. ENABLE_AUDIO_DUMP := true
5. endif
6. LOCAL_SRC_FILES:= /
7. AudioHardwareGeneric.cpp /

(4)编译一个应用程序(APK)

java代码：

(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：

java代码：

1. LOCAL_PATH := $(call my-dir)
2. include $(CLEAR_VARS)
3. 
4. # Build all java files in the java subdirectory-->直译（建立在java子目录中的所有Java文件）
5. LOCAL_SRC_FILES := $(call all-subdir-java-files)
6. 
7. # Name of the APK to build-->直译（创建APK的名称
8. ）
9. LOCAL_PACKAGE_NAME := LocalPackage
10. 
11. # Tell it to build an APK-->直译（告诉它来建立一个APK）
12. include $(BUILD_PACKAGE)

(5)编译一个依赖于静态Java库(static.jar)的应用程序

java代码：

1. LOCAL_PATH := $(call my-dir)
2. include $(CLEAR_VARS)
3. 
4. # List of static libraries to include in the package
5. LOCAL_STATIC_JAVA_LIBRARIES := static-library
6. 
7. # Build all java files in the java subdirectory
8. LOCAL_SRC_FILES := $(call all-subdir-java-files)
9. 
10. # Name of the APK to build
11. LOCAL_PACKAGE_NAME := LocalPackage
12. 
13. # Tell it to build an APK
14. include $(BUILD_PACKAGE)

(6)编译一个需要用平台的key签名的应用程序

java代码：

1. LOCAL_PATH := $(call my-dir)
2. include $(CLEAR_VARS)
3. 
4. # Build all java files in the java subdirectory
5. LOCAL_SRC_FILES := $(call all-subdir-java-files)
6. 
7. # Name of the APK to build
8. LOCAL_PACKAGE_NAME := LocalPackage
9. 
10. LOCAL_CERTIFICATE := platform
11. 
12. # Tell it to build an APK
13. include $(BUILD_PACKAGE)

(7)编译一个需要用特定key前面的应用程序

java代码：

1. LOCAL_PATH := $(call my-dir)
2. include $(CLEAR_VARS)
3. 
4. # Build all java files in the java subdirectory
5. LOCAL_SRC_FILES := $(call all-subdir-java-files)
6. 
7. # Name of the APK to build

9. 
10. LOCAL_CERTIFICATE := vendor/example/certs/app
11. 
12. # Tell it to build an APK
13. include $(BUILD_PACKAGE)

(8)添加一个预编译应用程序

java代码：

1. LOCAL_PATH := $(call my-dir)
2. include $(CLEAR_VARS)
3. 
4. # Module name should match apk name to be installed.
5. LOCAL_MODULE := LocalModuleName
6. LOCAL_SRC_FILES := $(LOCAL_MODULE).apk
