Issues with cargo-apk + winit 0.19.0

[VZout]

I'm trying to use cargo-apk with winit 0.19.0.

Sadly when I run cargo apk build --target ... I get the following error:

What causes this issue? Is it because winit is a dependency and I don't use android_glue directly?

The only way it works currently is with goddessfreya/winit#2. The current cargo-apk implementation is in https://github.com/rust-windowing/android-ndk-rs

Thanks for your reply. I'm slightly confused. Will android-glue be completely deprecated in favor of android-ndk-rs? What is exactly the difference between glue and android-ndk-rs?

[dvc94ch]

yes, this repo is deprecated. the difference is that one is maintained while the other is not. @Osspial can we archive this repo?

Does android-ndk-rs work with winit 0.19?

[dvc94ch]

No, winit needs to integrate with the native activity. Here the native-app-glue is used to interact with the native activity. But there are multiple issues with that, for example native-app-glue doesn't handle orientation changes or viewport changes when the keyboard pops up. android-ndk-rs uses the native activity directly.

Thanks to @JasperDeSutter there's android support in winit master now rust-windowing/winit#1556
