如何写Android.mk

如何将第三方的APK 加入到我们自己的 img 里面呢？

如果只有apk ：

一：在/vendor/....../generic/apps/ 目录下创建新的目录如：test/

二：将apk 文件(如：AAA.apk)直接copy 到/vendor/....../generic/apps/test/ 目录中

三：在test 目录中创建Android.mk 文件，即此文件和AAA.apk 在同一目录下

四：编写Android.mk 脚本：

LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_POST_PROCESS_COMMAND := $(shell cp -r $(LOCAL_PATH)/AAA.apk$(TARGET_OUT)/app/)

如果有多个apk需要添加，直接复制LOCAL_POST_PROCESS_COMMAND............ 这一句，然后将AAA.apk 改为相应的名字即可。

保存脚本，编译sdk ，系统会自动将apk 文件copy 到/out/target/....../system/app 中，并将apk添加到system.img 中

TARGET_ROOT_OUT: 表示根文件系统 out/target/product/root/

TARGET_OUT: 表示system文件系统 out/target/product/system/

TARGET_OUT_DATA: 表示data文件系统 out/target/product/data/

如果只有源码，没有apk

一：将源码文件夹(test)copy 到/vendor/....../generic/apps/ 目录下创建新的目录下

二：在源码文件夹test 目录中创建Android.mk 文件

三：编写Android.mk 脚本：

。。。。。。。

保存脚本，编译sdk ，系统会自动编译源码生成对应的apk 文件，并且将其放到/out/target/....../system/app 中，最终将apk添加到system.img 中

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)

编译一个依赖静态.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)

编译一个需要platform 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 := platform

# Tell it to build an APK

include $(BUILD_PACKAGE)

编译一个需要特殊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)

添加一个第三方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)

LOCAL_CERTIFICATE := platform

include $(BUILD_PREBUILT)

第三方APK针对需要.so的apk的示例如下：

LOCAL_PATH := $(my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE := baiduinput_android_v1.1_1000e

LOCAL_SRC_FILES := $(LOCAL_MODULE).apk

LOCAL_MODULE_CLASS := APPS

LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)

LOCAL_CERTIFICATE := platform

include $(BUILD_PREBUILT)

#################################################################

####### copy the library to /system/lib #########################

#################################################################

include $(CLEAR_VARS)

LOCAL_MODULE := libinputcore.so

LOCAL_MODULE_CLASS := SHARED_LIBRARIES

LOCAL_MODULE_PATH := $(TARGET_OUT_SHARED_LIBRARIES)

LOCAL_SRC_FILES := lib/$(LOCAL_MODULE)

OVERRIDE_BUILD_MODULE_PATH := $(TARGET_OUT_INTERMEDIATE_LIBRARIES)

include $(BUILD_PREBUILT)

添加静态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)
