Android and iOS builds of onnxruntime

[raphaelmenges]

Hello again 👋

According to the availability grid in the onnxruntime repository, onnxruntime is also available as native Android and iOS libraries. Are there any plans (or obstacles) to provide static builds of onnxruntime for these targets?

Unfortunately, we have no plans to setup build configurations for mobile devices for now because we don't have much time to focus on this project. 😢

You can find the ios support in
https://github.com/csukuangfj/onnxruntime-libs/blob/master/.github/workflows/ios.yaml

As for Android, I suggest that you download the pre-built libs from Microsoft.

For your convenience, you can download libs for iOS and Android from

If you two guys want onnxruntime static libs for android, please have a look at

https://github.com/csukuangfj/onnxruntime-libs/releases/tag/v1.17.1

Caution: Don't be scared of the file size after unzipping them, which is about 1GB.

A super large static library file size does not imply that the app file size is also large.

From my experience, please see the screenshot below from sherpa-onnx
