用超級用戶建立Android

Question

有沒有人知道如何從源代碼（AOSP）構建android時包含超級用戶權限？

Answer 1

爲了得到一個根（ED）殼，編輯system/core/rootdir或在機器人源相關聯到您的設備（例如爲device/ti/panda/init.rc PANDABOARD）的init.rc，和改變那些行：

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

成：

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

要嵌入Superuser.apk在AOSP，你必須獲取和建設：

1. su-binary（例如在external/）和存根/刪除system/extras/su包。
2. Superuser（例如，在packages/app/）

也可能必須設置的/system/xbin/su粘滯位在SU-二進制/ Android.mk。例如，我使用以下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)
