Necesito compilar una aplicación con android.mk en el árbol de compilación de aosp. Tengo un .arr lib personalizado conmigo, que reside en la siguiente carpeta apps / libs / mylib.aar

Cualquiera puede decirme cómo incluir el AAR en la compilación de Android AOSP. Ya probé los siguientes métodos descritos aquínlace @Stackoverflow para la compilación de aosp con .aar lib

Android.mk se parece a

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

LOCAL_MODULE_TAGS  := optional
LOCAL_PACKAGE_NAME := sample
LOCAL_CERTIFICATE  := platform

# SRC files
#=====================================================================
LOCAL_AIDL_INCLUDES := $(LOCAL_PATH)/aidl
LOCAL_SRC_FILES := $(call all-java-files-under, src) \
                   $(call all-Iaidl-files-under, aidl)

# RES files
#=====================================================================
LOCAL_RESOURCE_DIR := $(LOCAL_PATH)/res
LOCAL_RESOURCE_DIR +=prebuilts/sdk/current/extras/constraint-layout/res
LOCAL_RESOURCE_DIR +=frameworks/support/v7/appcompat/res
LOCAL_RESOURCE_DIR +=frameworks/support/design/res
LOCAL_RESOURCE_DIR +=frameworks/support-v4/res

LOCAL_MANIFEST_FILE :=AndroidManifest.xml
LOCAL_USE_AAPT2 := true
LOCAL_PROGUARD_ENABLED := disabled

# static .aar files
#=====================================================================
LOCAL_STATIC_JAVA_AAR_LIBRARIES:= mylib.aar

#Adding aapt packages
#=====================================================================
LOCAL_AAPT_FLAGS := --auto-add-overlay

LOCAL_AAPT_FLAGS += --extra-packages android.support.v7.appcompat 
LOCAL_AAPT_FLAGS += --extra-packages android.support.v7.recyclerview
LOCAL_AAPT_FLAGS += --extra-packages android.support.annotations
LOCAL_AAPT_FLAGS += --extra-packages android.support.v4
LOCAL_AAPT_FLAGS += --extra-packages android.support.design
LOCAL_AAPT_FLAGS += --extra-packages com.sample.mylib

#Include Static libraries
#=====================================================================
LOCAL_STATIC_JAVA_LIBRARIES := android-support-v7-appcompat
LOCAL_STATIC_JAVA_LIBRARIES := android-support-v7-recyclerview
LOCAL_STATIC_JAVA_LIBRARIES += android-support-v4
LOCAL_STATIC_JAVA_LIBRARIES += android-support-v7-gridlayout

LOCAL_STATIC_JAVA_LIBRARIES += android-support-design
LOCAL_STATIC_JAVA_LIBRARIES += gson
LOCAL_STATIC_JAVA_LIBRARIES += zxing
LOCAL_STATIC_JAVA_LIBRARIES += picasso

#Set out path
#=====================================================================
LOCAL_MODULE_PATH := $(TARGET_OUT_VENDOR_APPS)

#For build the application package
#=====================================================================
include $(BUILD_PACKAGE)

include $(CLEAR_VARS)
LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES := mylib:libs/mylib.aar
LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES += gson:libs/gson-2.8.1.jar
LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES += zxing:libs/core-3.3.3.jar
LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES += picasso:libs/picasso.jar

include $(BUILD_MULTI_PREBUILT)

include $(call all-makefiles-under,$(LOCAL_PATH))

Revisé diferentes enfoques para construir el mismo.
