Describe the bug

See 7ba710e

Trying to compile examples/hello_world for Android I get the following errors:

error: could not compile `arboard` due to 2 previous errors

These errors appear to be related to 1Password/arboard#56. I seems like arboard doesn't provide clipboard support on Android.

I can get rid of these errors by disabling the clipboard feature for eframe when compiling for Android. paulotten@68cdf23

error: could not compile `glutin` due to 3 previous errors

These errors appear to be related to rust-windowing/glutin#1307. The fix for this was merged in May and should be included in glutin 0.29.0. Currently eframe is using glutin 0.28.0. So it looks like an update is needed.

Updating to glutin = { version = "0.29.0" } results in the following error when building for Windows

I've created a PR for glutin.

For now I can work around this by updating glutin_egl_sys to 0.1.6 in Cargo.lock.

More errors now (still building for Windows):

note: perhaps two different versions of crate winit are being used?

rustc may to be right on this. https://crates.io/crates/glutin/0.29.0/dependencies reports winit ^0.27.1. https://crates.io/crates/eframe/0.18.0/dependencies reports ^0.26.1.

paulotten · 2022-08-10T01:58:23Z

Updating winit to 0.27.1 get me compiling successfully for both Windows and Android!

On Android I'm just getting a black screen when the app runs though.

I've also picked up a deprecated warning.

warning: use of deprecated associated function `winit::event_loop::EventLoop::<T>::with_user_event`: Use `EventLoopBuilder::<T>::with_user_event().build()` instead.

    = note: `#[warn(deprecated)]` on by default

I'll look into both of these more.

paulotten · 2022-08-10T02:00:39Z

So I seem to be duplicating #1877. Maybe I should wait on that?

This looks like a stale issue now that upstream glutin has been fixed for Android (and also completely refactored to be more suitable) :)
