I'm not sure how to get RUST_BACKTRACE=1 to the emulator. I also tried turning off MSAA for bevy and using 'WgpuSettingsPriority::Compatibility' with no luck. Issue has been created at wgpu also

[dt665m]

For those who run into this, I fixed it following directions in another issue by doing this:

#[cfg(target_os = "android")]
{
      app.insert_resource(Msaa::Off);
      default_plugins = default_plugins.set(RenderPlugin {
          render_creation: RenderCreation::Automatic(WgpuSettings {
              backends: Some(Backends::VULKAN),
               ..default()
          }),
          ..default()
      });
}

For some reason the default settings are not detecting things correctly on my MacOS android emulator environment. MSAA must be off or the emulator chokes pretty hard.

From macOS, I also have to force using vulkan otherwise it doesn't work. @akfpnd does that helps?

}

Then default_plugins will use in
app.add_plugins(default_plugins)?
and how to initialise default_plugins?

DefaultPlugin implements PluginGroup so you can just use DefaultPlugin::set(...) if you have other settings you need to modify. If set is the only thing you called, you'll get a builder. The builder also has a set function so you can chain.

This worked for me, thank you. I ripped out the other plugins from the mobile example for simplicity, maybe not wise in general.

My code

use bevy::{
  input::touch::TouchPhase,
  prelude::*,
  render::{
      settings::{Backends, RenderCreation, WgpuSettings},
      RenderPlugin,
  },
  window::{ApplicationLifetime, WindowMode},
};

// the `bevy_main` proc_macro generates the required boilerplate for iOS and Android
#[bevy_main]
fn main() {
  // MSAA makes some Android devices panic, this is under investigation
  // https://github.com/bevyengine/bevy/issues/8229
  let mut app = App::new();
  app.insert_resource(Msaa::Off);
  app.add_plugins(DefaultPlugins.set(RenderPlugin {
      render_creation: RenderCreation::Automatic(WgpuSettings {
          backends: Some(Backends::VULKAN),
          ..default()
      }),
      ..default()
  }))
  .add_systems(Startup, (setup_scene, setup_music))
  .add_systems(Update, (touch_camera, button_handler, handle_lifetime));

  app.run();
