Clicks not recogniced on Android

[michaelrampl]

The following "on update system" works well on desktop. Unfortunately, on mobile I cannot get it working properly. It seems like clicks/taps are not recognized so even I create other elements such as sliders, dropdowns, ... and try to tap them, nothing happens.

fn update_menu(mut egui_context: ResMut<EguiContext>) {
    egui::containers::Area::new("main_container").show(egui_context.ctx_mut(), |ui| {
    ui.button("click me");
...

These are my dependencies

[dependencies.bevy]
version = "0.9.0"
default-features = false
features = [
  "render",
  "bevy_asset",
  "png",
  "x11"
]

[dependencies.bevy_egui]
version = "0.17.1"
default-features = false
features = [
  "default_fonts"
]

As far as I have seen in https://github.com/rust-windowing/android-ndk-rs, egui should work on android so what am I missing here? (I'm using cargo apk to build the android package)

Hi! Thanks for creating the issue. Touch events support just doesn't exist in bevy_egui atm.
It was also mentioned in #104 (that issue was originally about touch events support in web though), and @michaelrampl suggested a patch that implements it. Tbh, I totally forgot to look into it. I'll try to test it next weekend and will create a new release if everything is working.

I would be glad to help testing once this has been merged ....
Anyway I wonder - The PR seems to add something to winit even tough bevy uses this already and touch is working in plain bevy apps for me (just implemented zoom gestures the other day. So are we sure that we need to fix that in winit?

@michaelrampl I meant this patch specifically: #104 (comment).
It shouldn't require any changes to winit.
