Description

3Drendering example works on my Mac but does not work on Android device (Pixel XL). It crashes on application boot. #4393 seems to have gotten it working but not correctly. Any thoughts on what is going on here?

Does building other applications (such as touchtracer) work? These errors do not seem immediately related to the 3d rendering example, I could be wrong here though..

Are you running buildozer on OSX? I'm not up to date, but in the old days a linux VM was significantly easier than getting it working correctly... maybe someone can chime in with more up to date info here..

Other applications work, I'm able to build a app using the vibration sensor for example. I haven't specifically tried touchtracer, but I can and will report back.

Okay, I tried same 3Drendering example with the Linux VM and I get same issue, it crashes on boot.

Not sure what's happening, but it seems it doesn't like a glDrawElements call in the VBO module.

which of there is only one: https://github.com/kivy/kivy/blob/master/kivy/graphics/vbo.pyx#L232 so it could be a good starting point to look at what's causing it.

Last time i checked, 3D model loading in kivy on android worked, although i didn't check this particular example.

Tried with master through manually built Kivy Launcher on Android 4.4.1 and it works just fine. Just a wild guess, but shouldn't it use GLES 2 instead?

If I'm manually compiling, how could I specify the gles version? I'm hitting this issue on Nexus 6, Android 7.1 with py3 with Crystax NDK.

I recently hit the issue with kivy3dgui. I'm still trying to dig the issue, but i saw some error about vertex attribute not declared in the shader, therefore any attempts to bind them will fail with GL error. However, after fixing thoses in the Kivy source code, i still get the crash. Didn't find the real deal here yet.

I haven't found the root of the segfault. It happen directly after the next glDrawElements when the vertex format change (aka when switching to other glAttribVertexPointer). Everything is correctly disabled before enabling the new vertex format. The shader is correctly bound.

I got an OnePlus 3T, Android 8.0.0. Maybe be an issue with the driver then.

Get the same error on Redmi 5 Plus, and any other apk with shaders get this error! Python 3.5, Kivy 1.11.1

hello, I had a very similar problem on a xiaomi redmi note 9s, my shader worked perfectly on the huawei p30 pro but not on the xiaomi. The solution is to use texture2D (texture0, tex_coord0) when assigning the values to the gl_FragColor, I think it is due to the close relationship between the vertex shader and the fragment, this is an example of my shader taken from shadertoy with adaptation of my part.

Hello, doing some tests at the end I managed to get Suzzane's example working using pydroid on a motorola, the adjustment I made to the code was in the simple.glsl and it is the following, I hope it will be useful for you in the future

/* simple.glsl

simple diffuse lighting based on laberts cosine law; see e.g.:
    http://en.wikipedia.org/wiki/Lambertian_reflectance
    http://en.wikipedia.org/wiki/Lambert%27s_cosine_law

    //compute vertex position in eye_space and normalize normal vector
    vec4 pos = modelview_mat * vec4(v_pos,1.0);
    vertex_pos = pos;
    normal_vec = vec4(v_normal,0.0);
    gl_Position = projection_mat * pos;

I recently ran into a similar bug with a custom shader on Adreno GPUs.

I think the reason is this -> https://kivy.org/doc/stable/api-kivy.graphics.shader.html#header-inclusion

Kivy will always include default parameters.

After taking a look at the default shaders and adopt some naming, my shader worked as expected. It looks like Adreno (and probably other GPUs) don't like receiving parameters which are not declared or declared multiple times in the shader file, although other GPUs are less picky.

Maybe someone is motivated to double check, so this issue finally can be closed.
