Description

We are trying to build a project with the onnxruntime library. Due to the onnxruntime is not on the recipes list so it will be build with the pip command by default.

The apk can be generated successfully but will crashed when it try to load the onnxruntime lib due to the lib is 64-bit.

Does anyone have idea to build this library? From the onnxruntime document we can build a standalone libonnxruntime.so, but it is not suitable to use for our project.

buildozer.spec

Command:
We use p4a to generate the apk so there is no buildozer.spec file.

p4a apk --private ./ --requirements=python3,kivy,...,.......,onnxruntime --bootstrap=sdl2 --arch=armeabi-v7a --package=example.python2 --name "test_python2" --dist_name="test_python2" --ndk_dir=... --sdk_dir=... --release --android-api 30 --version 1.1

Logs

The app will crash with the following log.

We check the so file and it seems the onnxruntime_pybind11_state.so was built with host compiler.

so it will be build with the pip command by default.

This assumption is incorrect, that is why recipes exist.

This binary was downloaded from Pypi by pip (and not built)

Your options are either create a recipe or use Pyjnius and the Java api.
