Hi,
I tried with NDK r9c.
But I still have some problem:

I still see it trying to execute with "ALL" abi even if I specified
arm-only ABI. and APP PLATFORM 18 even if I specified version 9.
Anyway the error is about assimp/Importer.hpp missing.
In my Android.mk I have this:
LOCAL_EXPORT_C_INCLUDES := ${PROJECT_PATH}/assimp/include
witch worked before.
PROJECT_PATH is computed like this:
PROJECT_PATH := $(abspath $(call my-dir)/../../../)
The path is correct because it would complain about missing assimp.so
otherwise.
This is my Android.mk

Am I doing something wrong?
If this can't be easily solved is there a way to disable the default NDK
from the plugin and leave my previous code running?
Thank you!
Cheers,
Daniele
