如何使用Ndk为Android Apps构建ADB

Question

我想用NDK构建Android ADB，以便获得的.so可以在我的项目中使用.mk文件，如下所示：

# Copyright 2005 The Android Open Source Project
#
# Android.mk for adb
#

LOCAL_PATH:= $(call my-dir)
#adbd device daemon
# =========================================================

include $(CLEAR_VARS)

LOCAL_SRC_FILES := \
adb.c \
fdevent.c \
transport.c \
transport_local.c \
transport_usb.c \
adb_auth_client.c \
sockets.c \
services.c \
file_sync_service.c \
jdwp_service.c \
framebuffer_service.c \
remount_service.c \
usb_linux_client.c

LOCAL_CFLAGS := \
-O2 \
-g \
-DADB_HOST=0 \
-D_XOPEN_SOURCE \
-D_GNU_SOURCE \
-Wall -Wno-unused-parameter -Werror -Wno-deprecated-declarations \

ifneq (,$(filter userdebug eng,$(TARGET_BUILD_VARIANT)))
LOCAL_CFLAGS += -DALLOW_ADBD_ROOT=1
endif

LOCAL_MODULE := adbd

LOCAL_FORCE_STATIC_EXECUTABLE := true
LOCAL_MODULE_PATH := $(TARGET_ROOT_OUT_SBIN)
LOCAL_UNSTRIPPED_PATH := $(TARGET_ROOT_OUT_SBIN_UNSTRIPPED)

LOCAL_STATIC_LIBRARIES := liblog libcutils libc libmincrypt libselinux
LOCAL_ADDITIONAL_DEPENDENCIES := $(LOCAL_PATH)/Android.mk
include $(BUILD_EXECUTABLE)

但是我无法通过android-ndk-r9c来构建它

这种方式可行吗？ 我该怎么办 ？

有人可以帮我吗？

构建过程中的错误是：

在将coressphonding lib添加到floder之后，我尝试通过ndk在linux中构建它，解决了一些错误，但是重定义仍然存在，我注释了重定义结构，但是出现了新问题：

linux/capability.h:35:10: error:expected '=', ',' , 'j','asm' or'__attribute__' before '*' token } __user * cap_user_header_t

顺便说一句，我真正想要的是在apk中运行adb命令，例如“ adb install”。是否需要将整个adbd程序移到我的项目中？ 有什么办法可以做到这一点？

Answer 1

这是不可能的，adbd依赖于NDK未公开的系统库，其中一些在平台发行版之间已更改。 此外，它需要以适当的特权运行才能正常工作，而这是您无法从应用程序中完成的。

Answer 2

您可以从Android设备的源代码构建adb和fastboot。
使用此构建脚本， github
在此版本库中，您可以看到arm-v7a和arm64的预编译二进制文件
