            abiFilters "armeabi", "armeabi-v7a", "x86"
            cFlags "-I\$(LOCAL_PATH)/jnispeex.cpp -I\$(LOCAL_PATH)/jnicelt11.cpp -I\$(LOCAL_PATH)/jnicelt7.cpp -I\$(LOCAL_PATH)/jniopus -D__EMX__ -DUSE_KISS_FFT -DFIXED_POINT -DEXPORT='' -DHAVE_CONFIG_H -fvisibility=hidden -DOPUS_BUILD -DVAR_ARRAYS -Wno-traditional -DFIXED_POINT"
