I am trying to use gfx on the Android platform, but one problem after another, finally, I met the first gfx problem. My codes as the following

 let el = EventLoop::new();
    el.run(move |event, el, control_flow| {
        *control_flow = ControlFlow::Wait;
        match event {
            Event::Resumed => unsafe {
                log::info!("window resumed");
                let window_builder = WindowBuilder::new().with_title("hello");
                let window = ContextBuilder::new()
                    .build_windowed(window_builder, el)
                    .unwrap()
                    .make_current()
                    .unwrap();
                log::info!("windows created");
                let surface_extent = Extent2D {
                    width: 1024,
                    height: 768,
                };
                // The `instance` is an entry point to the graphics API. The `1` in the
                // call is a version number - we don't care about that for now.
                //
                // The `surface` is an abstraction of the OS window we're drawing into.
                // In `gfx`, it also manages the swap chain, which is a chain of
                // multiple images for us to render to. While one is being displayed, we
                // can write to another one - and then swap them, hence the name.
                //
                // The `adapter` represents a physical device. A graphics card for example.
                // The host may have more than one, but below, we just take the first.
                let (instance, surface, adapter) = {
                    let instance =
                        backend::Instance::create(APP_NAME, 1).expect("Backend not supported");
                    let surface = instance
                        .create_surface(window.window())
                        .expect("Failed to create surface for window");

                    let adapter = instance.enumerate_adapters().remove(0);

                    (instance, surface, adapter)
                };

I also tried to use gfx-backend-gl but create_surface also failed with 'BadAlloc'.
