Android NDK setup for speex

Question

I am trying to integrate speex in my program and just downloaded NDK for it. I have trouble with setup Android NDK (I am on Mac OS). When I type

./ndk-build -C ../android_dev/oler_android/

Android NDK: Your APP_BUILD_SCRIPT points to an unknown file: 
~/Desktop/android_dev/oler_android//jni/Android.mk    
make: Entering directory `/Users/Oler/Desktop/android_dev/oler_android'
/Users/Oler/Desktop/android-ndk/build/core/add-application.mk:187: *** Android NDK:        
Aborting...    .  Stop.
make: Leaving directory `/Users/Oler/Desktop/android_dev/oler_android'

I have created Application.mk and Android.mk under jni folder.

The out put for ./ndk-build NDK_LOG=1

Have you installed and included all the required files? Does your Makefile looks like that - check if something is missing:

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE    := libspeex
LOCAL_CFLAGS = -DFIXED_POINT -DUSE_KISS_FFT -DEXPORT="" -UHAVE_CONFIG_H
LOCAL_C_INCLUDES := $(LOCAL_PATH)/include

LOCAL_SRC_FILES :=  \
./libspeex/bits.c \
./libspeex/buffer.c \
./libspeex/cb_search.c \
./libspeex/exc_10_16_table.c \

include $(BUILD_SHARED_LIBRARY)

The best path to take is to have a double check in the project config and the installation setups.
