构建Android具有超级用户 [英] Build Android with Superuser

问题描述

有谁知道如何从源代码构建机器人时，包括超级用户的权限？

Does anyone know how to include super-user privileges when building android from source?

请让我知道，如果你做的！

Please let me know if you do!

谢谢， 凯文

推荐答案

要获得根（ED）的外壳，编辑系统/核心/ ROOTDIR 或init.rc关联到你的android的源设备（例如设备/ TI /熊猫/ init.rc 的PANDABOARD），并更改这些行：

To get a root(ed) shell, edit system/core/rootdir or the init.rc associated to your device (e.g. device/ti/panda/init.rc for pandaboard) in android sources, and change those lines:

service console /system/bin/sh
    class core
    console
    disabled
    user shell
    group log

到

service console /system/bin/sh
    class core
    console
    disabled
    user root 
    group root

要嵌入Superuser.apk在AOSP，你必须获取并建立：

To embed Superuser.apk in AOSP, you have to fetch and build:

1. 苏二进制（如外部/ ）和存根/删除系统/演员/苏包。
2. 超级用户（如封装/应用/ ）

1. su-binary (e.g. in external/) and stub/remove system/extras/su package.
2. Superuser (e.g. in packages/app/)

您可能还需要设置 /系统/ XBIN /苏的苏二进制/ Android.mk粘滞位。举例来说，我用下面的Makefile：

You may also have to set the sticky bit of /system/xbin/su in su-binary/Android.mk. For instance, I used following makefile:

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)

LOCAL_MODULE := su
LOCAL_SRC_FILES := su.c db.c activity.cpp

SU_SHARED_LIBRARIES := liblog libsqlite
ifeq ($(PLATFORM_SDK_VERSION),4)
    LOCAL_CFLAGS += -DSU_LEGACY_BUILD
    SU_SHARED_LIBRARIES += libandroid_runtime
else
    SU_SHARED_LIBRARIES += libcutils libbinder libutils
    LOCAL_MODULE_TAGS := eng
endif

LOCAL_C_INCLUDES += external/sqlite/dist

LOCAL_SHARED_LIBRARIES := $(SU_SHARED_LIBRARIES)

LOCAL_MODULE_PATH := $(TARGET_OUT_OPTIONAL_EXECUTABLES)


SU_INSTALL_DIR := $(TARGET_OUT)/xbin
SU_BINARY := $(SU_INSTALL_DIR)/su
# taken from busybox-android
$(SU_BINARY)-post: su
    @echo "Setting SUID/GUID to su-binary..."
    chmod ug+s $(TARGET_OUT_OPTIONAL_EXECUTABLES)/su

SU_CMD := su
SYMLINKS := $(addprefix $(TARGET_OUT_EXECUTABLES)/,$(SU_CMD))
$(SYMLINKS): $(LOCAL_INSTALLED_MODULE) $(SU_BINARY)-post $(LOCAL_PATH)/Android.mk
    @echo "Symlink: $@ -> /system/xbin/$(SU_CMD)"
    @mkdir -p $(dir $@)
    @rm -rf $@
    @ln -sf /system/xbin/$(SU_CMD) $@

ALL_DEFAULT_INSTALLED_MODULES += $(SU_BINARY)-post $(SYMLINKS)

include $(BUILD_EXECUTABLE)
