add cpp classes into android project

How can I add a .cpp class (like speex or opus) into my android studio project ?
I already tried to insert using externalNativeBuild like :

externalNativeBuild
ndkBuild
arguments "NDK_APPLICATION_MK:=Application.mk"
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"




but it does't work.
I will be so appreciated if anyone helps

you should use CMakelists.txt for your Android NDK build and configure your CPP files inside the Cmakelists.txt. Some related links for your reference:
