Futher analysis of the APK shows that libpython3.5m.so and libmain.so are available for each architecture, but libcrystax.so is missing. I was under the impression that the python module would import any other modules that it requires (ie. libcrystax.so), but I apologize if I'm wrong. Either way, some tips on how to get this sorted out would be appriciated.

So it turns out gradle's ndkBuild command uses the ndk-build tool from the sdk, not from the ndk. It's not a crystax problem. Also I recognize i did some weird stuff with the libs/start.c and I resolved that.

I take that back, it runs the correct ndk-build, but doesn't copy libcrystax.so

This is what it runs:

/home/marcel/crystax-ndk-10.3.2/ndk-build-backup NDK_PROJECT_PATH=$(pwd) APP_BUILD_SCRIPT=/home/marcel/workspace/Test/app/src/main/jni/Android.mk APP_ABI=mips NDK_ALL_ABIS=mips NDK_DEBUG=1 APP_PLATFORM=android-18 NDK_OUT=/home/marcel/workspace/Test/app/build/intermediates/ndkBuild/debug/obj NDK_LIBS_OUT=/home/marcel/workspace/Test/app/build/intermediates/ndkBuild/debug/lib /home/marcel/workspace/Test/app/build/intermediates/ndkBuild/debug/obj/local/mips/libmain.so

It works with just:
