Guide for AOSP developers

[shlatchz]

Is there a guide on how to add both the su executable and the SuperUser application to the AOSP build and compile it along with the rest of the AOSP code?
Do I just copy the su part to /system/extras/su/
and the application to /packages/apps/ ? While Android.mk should I use for the app?
A guide for that would be awesome.

Thanks!

I've installed the su, using the following Android.mk:

# Root AOSP source makefile
# su is built here, and 

my_path := $(call my-dir)

SUPERUSER_EMBEDDED := true

LOCAL_PATH := $(my_path)

include $(CLEAR_VARS)

LOCAL_MODULE := su

LOCAL_MODULE_TAGS := eng debug optional

LOCAL_LDFLAGS := -static

LOCAL_FORCE_STATIC_EXECUTABLE := true

LOCAL_C_INCLUDES := include/

LOCAL_STATIC_LIBRARIES := \
    liblog \
    libc \
    libselinux \
    libcutils

LOCAL_SRC_FILES := su.c daemon.c activity.c db.c utils.c pts.c sqlite3.c hacks.c binds.c

LOCAL_CFLAGS := -DSQLITE_OMIT_LOAD_EXTENSION -std=gnu11

LOCAL_CFLAGS += -DREQUESTOR=\"$(shell cat $(LOCAL_PATH)/packageName)\"

ifdef SUPERUSER_EMBEDDED
  LOCAL_CFLAGS += -DSUPERUSER_EMBEDDED
endif

LOCAL_MODULE_PATH := $(TARGET_ROOT_OUT_SBIN)

include $(BUILD_EXECUTABLE)

ifdef SUPERUSER_EMBEDDED

# make sure init.superuser.rc is imported from
# init.rc or similar

SUPERUSER_RC := $(TARGET_ROOT_OUT)/init.superuser.rc
$(SUPERUSER_RC): $(LOCAL_PATH)/init.superuser.rc | $(ACP)
    $(copy-file-to-new-target)

SUPERUSER_MARKER := $(TARGET_OUT_ETC)/.has_su_daemon
$(SUPERUSER_MARKER): $(LOCAL_INSTALLED_MODULE)
    @mkdir -p $(dir $@)
    @rm -rf $@
    $(hide) touch $@

ALL_MODULES.$(LOCAL_MODULE).INSTALLED := \
    $(ALL_MODULES.$(LOCAL_MODULE).INSTALLED) $(SUPERUSER_RC) $(SUPERUSER_MARKER)

endif

And the Superuser app using the following Android.mk:

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

SUPERUSER_PACKAGE := com.koushikdutta.superuser

LOCAL_STATIC_JAVA_LIBRARIES := libarity android-support-v4
LOCAL_PACKAGE_NAME := Superuser

LOCAL_SRC_FILES := $(call all-java-files-under,src) $(call all-java-files-under,../Widgets/src)

LOCAL_AAPT_INCLUDE_ALL_RESOURCES := true
LOCAL_AAPT_FLAGS := --extra-packages com.koushikdutta.widgets -S $(LOCAL_PATH)/../Widgets/res --auto-add-overlay --rename-manifest-package $(SUPERUSER_PACKAGE)

include $(BUILD_PACKAGE)

Everything was compiled successfuly, and the Superuser program is visible, but I get this error in logcat:

09-27 11:59:00.516 1363 1363 W Superuser: java.io.IOException: Error running exec(). Command: [su] Working Directory: null Environment: null

Meaning that the app cannot run su command :/

[shlatchz]

Implementing the changes in here helped, but the SuperUser program is still buggy for me..

[airend]

Were you able to build the APK under N, with JDK8?

[mid-kid]

I would also love documentation on how to integrate this (particularly suhide) in AOSP/CM.

[arjunpprasad]

Hi shlatchz ,

I managed to build su with AOSP but seems the generated binaries are not the right one.

did you manage to complete the integration and get root access ?

I am working on snapdragon 820 , android 6.0.1.

Any suggestions/pointers please
