android JNI how to convert a CMAKE file to a JNI Android.mk with supporting files

I have a working Cmake android project and I am moving it to a new application where I cannot use Cmake. I need to convert it to use the Android JNI / Android.mk & Application.mk.. However I am having issues with the 2 directories of support files. One has namespace jni, the other appears to be mostly headers. Unfortunately the conversion does not seem as straight forward as the docs suggest.

The file structure is

src/main/cpp
            deps/otherlib/include
            deps/jni/include
            Android.mk
            Application.mk
    	    main.cpp logger.h
    	    foobar_handler.cpp
    	    foobar_handler.hpp
    	    foo_test.hpp
    	    foo_test.cpp   

When I try to sync the files, all the library files under deps/jni/include show unresolved references to anything in angle brackets. IE #include <jni/bar.hpp>

Its been a while since I have done anything with C++. I notice that the jni cpp files all have namespace jni
I think I am missing a step for it to work in my Android.mk. The CMAKE compiles fine, but I cannot use it. I tried adding it to LOCAL_EXPORT_C_INCLUDES with no success.

Android.mk

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


LOCAL_MODULE := native_crash_handler

LOCAL_SRC_FILES := \
	main.cpp logger.h \
	foobar_handler.cpp \
	foobar_handler.hpp \
	foo_test.hpp \
	foo_test.cpp


LOCAL_C_INCLUDES := $(LOCAL_PATH)

LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)

LOCAL_CFLAGS := -fexceptions -fno-omit-frame-pointer
LOCAL_CFLAGS += -Wall -Werror

CXX11_FLAGS := -std=gnu++11
LOCAL_CFLAGS += $(CXX11_FLAGS)

LOCAL_EXPORT_CPPFLAGS := $(CXX11_FLAGS)

LOCAL_LDLIBS := -llog




include $(BUILD_SHARED_LIBRARY)
