内置Apk到系统(Android10)
The following article is from 卓码空间 Author QDroid88888
1.Android.mk文件说明
Android.mk是Android提供的一个makefile文件,可以将源文件分组为模块。用来引用的头文件目录、需要编译的*.c/*.cpp文件、jni源文件、指定编译生成*.so共享库文件或者*.a静态库文件,可以定义一个或多个模块,也可以多个模块中使用同一个源文件。
为方便模块编译,编译系统设置了很多模块描述环境变量和宏定义,如下列举一些常用的。
模块描述环境变量:
LOCAL_SRC_FILES:
当前模块包含的源文件;
LOCAL_MODULE:
当前模块的名称;
LOCAL_PACKAGE_NAME
当前APK应用的名称;
LOCAL_C_INCLUDES:
C/C++所需的头文件路径;
LOCAL_STATIC_LIBRARIES:
当前模块在静态链接时需要的静态链接库名;
LOCAL_SHARED_LIBRARIES:
当前模块在运行时依赖的动态链接库名;
LOCAL_STATIC_JAVA_LIBRARIES:
当前模块依赖的Java静态库;
LOCAL_JAVA_LIBRARIES:
当前模块依赖的Java共享库;
LOCAL_CERTIFICATE:
当前应用的签名方式,比如使用系统签名platform。
LOCAL_MODULE_TAGS:
表示该模块编译的标识,可能值为eng,user,tests或optional(默认值)。值具体表示:
user:指该模块只在user版本下才编译
eng:指该模块只在eng版本下才编译
tests:指该模块只在tests版本下才编译
optional:指该模块在所有版本下都编译
定义的 include 变量:
include $(BUILD_SHARED_LIBRARY)
表示需要编译为so动态链接库。
include $(BUILD_JAVA_LIBRARY)
表示需要编译为java动态库。
include $(BUILD_JAVA_STATIC_LIBRARY)
表示需要编译为java静态库。
include $(BUILD_STATIC_LIBRARY )
表示需要编译为so静态库。
include $(BUILD_EXECUTABLE)
表示编译为Native C可执行程序
include $(BUILD_PREBUILT)
表示源文件已经是编译好的,只需要进行复制操作
定义的函数宏,原型为 $(call <function>)
,以下列举几个:
$(call my-dir)
获取当前文件夹路径;
$(call all-java-files-under, )
获取指定目录下的所有Java文件;
$(call all-c-files-under,)
获取指定目录下的所有C文件;
$(call all-Iaidl-files-under, )
获取指定目录下的所有AIDL文件;
2.提供几个Android.mk模板
#编译so静态库
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE = libtest
LOCAL_SRC_FILES = testxxx.c
LOCAL_C_INCLUDES = $(INCLUDES)
LOCAL_SHARED_LIBRARIES := libcutils
include $(BUILD_STATIC_LIBRARY)
#编译为so动态库链接库
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE = libtest
LOCAL_SRC_FILES = testxx.c
LOCAL_C_INCLUDES = $(INCLUDES)
LOCAL_SHARED_LIBRARIES := libcutils
include $(BUILD_SHARED_LIBRARY)
#编译java动态库
LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_SRC_FILES := $(call all-subdir-java-files)
LOCAL_MODULE := testjar
include $(BUILD_JAVA_LIBRARY)
#编译java静态库
LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_SRC_FILES := $(call all-subdir-java-files)
LOCAL_MODULE := testjar
include $(BUILD_STATIC_JAVA_LIBRARY)
#编译为可执行文件
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := hellos
LOCAL_STATIC_LIBRARIES := libhellos
LOCAL_SHARED_LIBRARIES :=
LOCAL_LDLIBS += -ldl
LOCAL_CFLAGS := $(L_CFLAGS)
LOCAL_SRC_FILES := mains.c
LOCAL_C_INCLUDES := $(INCLUDES)
include $(BUILD_EXECUTABLE)
#使用动态库
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := hellod
LOCAL_MODULE_TAGS := debug
LOCAL_SHARED_LIBRARIES := libc libcutils libhellod
LOCAL_LDLIBS += -ldl
LOCAL_CFLAGS := $(L_CFLAGS)
LOCAL_SRC_FILES := maind.c
LOCAL_C_INCLUDES := $(INCLUDES)
include $(BUILD_EXECUTABLE)
#预编so动态链接库到指定目录
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := libtest.so
LOCAL_MODULE_CLASS := SHARED_LIBRARIES
LOCAL_MODULE_PATH := $(ANDROID_OUT_SHARED_LIBRARIES)
LOCAL_SRC_FILES := lib/$(LOCAL_MODULE )
OVERRIDE_BUILD_MODULE_PATH := $(TARGET_OUT_INTERMEDIATE_LIBRARIES)
include $(BUILD_PREBUILT)
#预编二进制文件到系统
include $(CLEAR_VARS)
LOCAL_MODULE := testbin
LOCAL_SRC_FILES := testbin
LOCAL_MODULE_CLASS := EXECUTABLES
LOCAL_MODULE_TAGS := optional
include $(BUILD_PREBUILT)
# 内置Apk文件到系统
LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := adbinputmethod
LOCAL_MODULE_CLASS := APPS
LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)
LOCAL_MODULE_TAGS := optional
LOCAL_PRIVILEGED_MODULE := true
LOCAL_BUILT_MODULE_STEM := package.apk
LOCAL_SRC_FILES := $(LOCAL_MODULE).apk
# LOCAL_CERTIFICATE := platform
LOCAL_CERTIFICATE := PRESIGNED
include $(BUILD_PREBUILT)
3.源码中内置apk到系统
此处以内置搜狗输入法到系统为例说明。
(1). 创建存放内置App的目录,此处我创建为packages/myapps/sougou,如下所示:
qiang@ubuntu:~/lineageOs$ pwd
/home/qiang/lineageOs
qiang@ubuntu:~/lineageOs$ mkdir -p packages/myapps/sougou
qiang@ubuntu:~/lineageOs$
(2).将搜狗输入法apk复制到packages/myapps/sougou,并创建内置apk到系统的Android.mk。如下所示:
qiang@ubuntu:~/lineageOs/packages/myapps/sougou$ pwd
/home/qiang/lineageOs/packages/myapps/sougou
qiang@ubuntu:~/lineageOs/packages/myapps/sougou$ ls -la
total 58480
drwxrwxrwx 2 qiang qiang 4096 1月 1 18:22 .
drwxrwxr-x 3 qiang qiang 4096 1月 2 02:25 ..
-rwxrw-rw- 1 qiang qiang 755 1月 1 18:29 Android.mk
-rwxrw-rw- 1 qiang qiang 59870272 11月 3 07:35 sougou.apk
对应的Android.mk内容为:
# ///ADD START
# ///ADD END
# 设置当前工作路径
LOCAL_PATH:= $(call my-dir)
# 清除变量值
include $(CLEAR_VARS)
# 生成的模块名称
LOCAL_MODULE := sougou
# 生成的模块类型
LOCAL_MODULE_CLASS := APPS
# 生成的模块后缀名,此处为apk
LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)
# 设置模块tag,tags取值可以为:user debug eng tests optional
# optional表示全平台编译
LOCAL_MODULE_TAGS := optional
# LOCAL_PRIVILEGED_MODULE := true
LOCAL_BUILT_MODULE_STEM := package.apk
# 设置源文件
LOCAL_SRC_FILES := $(LOCAL_MODULE).apk
# LOCAL_CERTIFICATE := platform
# 设置签名,此处表示保持apk原有签名
LOCAL_CERTIFICATE := PRESIGNED
# 此处表示预编译方式
include $(BUILD_PREBUILT)
(3)将创建的搜狗输入法编译模块配置到编译系统,这个非常重要,如果不加入编译镜像默认是不会编译刚添加的模块。lineageOs中,可以在如下路径中添加Settings模块的地方追加sougou。
文件位置:
build/make/target/product/handheld_product.mk
添加sougou内容之后的部分内容如下:
PRODUCT_PACKAGES += \
Browser2 \
Calendar \
Camera2 \
Contacts \
DeskClock \
Gallery2 \
Launcher3QuickStep \
Music \
OneTimeInitializer \
Provision \
QuickSearchBox \
Settings \
SettingsIntelligence \
StorageManager \
SystemUI \
WallpaperCropper \
frameworks-base-overlays \
sougou
