How to compile a project with Android.Mk through a script.sh?

Question

I have a simple project with native code and am using manual command to compile /workspace/android-ndk-r11c/ndk-build TARGET_PLATFORM=android-14 TARGET_ARCH_ABI=armeabi NDK_PROJECT_PATH=..

In my project I have Android.Mk

LOCAL_PATH := $(call my-dir)

subdirs := $(addprefix $(LOCAL_PATH)/,$(addsuffix /Android.mk, \
        native_code \
    ))

ifeq($(TARGET_ARCH_ABI), armeabi-v7a)
    MY_INCLUDE := ../build/module_armeabi-v7a
endif

ifeq($(TARGET_ARCH_ABI), armeabi)
    MY_INCLUDE := ../build/module_armeabi
endif

ifndef MY_INCLUDE
$(error "You must define MY_INCLUDE before starting build_script.sh")
endif

include $(subdirs)

As you saw in the file Android.Mk above, I have the variable MY_INCLUDE, through the ifeq($(TARGET_ARCH_ABI) and according to the architecture passed in the TARGET_ARCH_ABI, I can compile for different architectures.

So with the command ndk-build I can compile perfectly, but I need it to Compile, not through command line with the ndk-build, but rather through a build script which would also pass the variable MY_INCLUDE for Android.Mk.

How could I compile by running the build_script.sh file?
