Android example crash

When using the latest release version on Android 8.1:
cargo apk r -p glutin_examples --example android
I get:

What could this be? WebGL works on this device.
(When running eframe there is an error with string "OpenGL ES-CM 1.1", I guess that's the ES version, but ES 3.1 should be supported on Android 8.1)
(OpenGL ES 2 example from the official Android NDK examples works)
@fr-an-k if you try previous versions of glutin, could you get it to work?
cc @MarijnS95
I tried 0.29.1, renamed examples/window.rs to lib.rs, then (in glutin_examples):
cargo apk run --lib
It builds, installs, reports success, but it crashes without error message as well.
I would suggest to try different patch versions of the glutin 0.30. Trying 0.29.1 is pointless.
0.30.6 appears to have the same issue
0.30.3 doesn't compile
0.30.0 outputs:

I didn't try the other ones.
Looks like there is a GL version check somewhere that does not know how to interpret "OpenGL ES-CM 1.1".
I would be nice if I could just tell it to request GL ES 2.0 rather than 3.2 which may be the default.
I suspect I may need to use the glutin_gles2_sys (now only used for macos).
But I can't spend much more time on this, so I guess I'll just have to wait until bevy/glow/winit/glutin receives better cross-platform support.
Looks like there is a GL version check somewhere that does not know how to interpret "OpenGL ES-CM 1.1".
glutin example doesn't have GL version checks. We use #version 100 shaders, and we ask the context to be either ES 3.1.
I would be nice if I could just tell it to request GL ES 2.0 rather than 3.2 which may be the default.
Instead of guessing you could read the code of the example. It requests 3 different versions of the context, and your system builds the context just fine from the logs.
I suspect I may need to use the glutin_gles2_sys (now only used for macos).
No, you don't need that, Android is using EGL, not the GLES bindings, the GLES bindings is an ios legacy thing.
But I can't spend much more time on this, so I guess I'll just have to wait until bevy/glow/winit/glutin receives better cross-platform support.
Yeah, it'll certainly get better without any trouble shooting.
The issue with the glutin example is not in the version check but either during window creation or EGLSurface creation.
What could help is if you could tell what exactly crashes(provide a simple stack trace) for you or if you could link to the working android example with open source software stack, so I could at least look how EGL is managed inside of it, if the issue is EGL.
I'd suggest to apply this:

To the latest master and retest.
Also, be aware that winit has both native and game activity, and by default we're using native one. So you might try to use game instead (change the feature in glutin_examples). The feature is https://github.com/rust-windowing/winit/blob/fbea75d31f4025825e9bf88b99d7c92e4eb79273/Cargo.toml#L46
In the 0.30.7 android example, the crash appears to originate in:
let attrs = window.build_surface_attributes(<_>::default());
gl_config.num_samples() is 4
Config supports API: GLES1
The context is using: Gles(None)
Patching the master results in the same.
Edit: also when I change to this in glutin_examples/Cargo.toml:
winit = { version = "0.28.1", default-features = false, features = ["game"] }
let attrs = window.build_surface_attributes(<_>::default());
This can't crash.
I don't see the println!("About to create surface for the window"); output, so it seems
like window creation crashes, not the glutin stuff.
You originally posted a log showing prints like RustStdoutStderr: Android window available, so if you can post the same with my patch that would be nice.
Config supports API: GLES1
So your system is GLES 1, not GLES 2 even, though, we provide a way to build the context for it.
Indeed I was wrong; sorry, I'm just beginner.
It appears to crash in:
gl_config.display().create_window_surface(&gl_config, &attrs).unwrap()

hello-gl2 from the NDK samples does work and actually reports creating an OpenGL ES 3.2 context:

return context;

Maybe an attribute is passed that this PowerVR Rogue driver doesn't like?
I think we should print the extensions we've loaded in the examples actually. It's really hard to tell what could be the case without any traces.
The only concern I have wrt the crash is that the error is in the extension coming from the EGL wrt native window. It would be nice to verify that at least.
In glutin android has KHR and normal display paths, so I think the normal path was took instead here.
@kchibisov Yes that would be useful. I was about to write that but then realized that the ext codepath doesn't handle Android, so it must be KHR in this case (or error because there's no display)... only to find the extension-less display handling now:
glutin/glutin/src/api/egl/display.rs
Line 296 in e2ba7f1
Yeah, android doesn't have the EXT extension, only KHR one. So it's not like it doesn't handle, it's not existent in the specification.
@kchibisov please, forgive me for not writing three more words on that.
When forcing the "legacy" extension-less display without extension, I get the exact same crash at the same address (perhaps because Android locks their EGL pointers in the same place)?

Found it, PR incoming.
I bet on wrong glutin_egl_sys definitions for this platform, given that original path needs a de-referenced window or such.
@kchibisov something like that, but not really. The API doesn't call for a dereferenced window at all, they just happen to use EGLNativeWindowType which is defined to a *const c_void and supposed to be interpreted as the value of Android's native window, just like all the other display creation code.
