[Android.GL] DrawRangeElementsBaseVertex() fails with 'called unimplemented OpenGL ES API'

[bosoni]

Sorry, I dont know how to copy development branchs android library where test uses.

But I just downloaded newest .exe and installed it, and created new project with newest nugets and works with desktop,
but not on android.

I included a little test, 2 images, both moving. Desktop shows them, android not.

If using only 1 image (test has other commented out) it shows just black box.

And when using 2 images, it renders only one black box, there isnt that other black box.

[tested that again using that .zip file below, and edited ^ texts because there were some errors]

KNI_Test_2.zip

What operating system are you using:

• Windows11

What KNI platform are you using:

Android

[bosoni]

More information (which I forgot):

Last year 6.11.2024 I tried KNI (desktop and web worked then and now) but on Android it shows texture when using only 1 image.

When using 2 images, 2 black boxes.

And when I tested

        spriteBatch.Begin();
        spriteBatch.Draw(texture2, new Vector2(300 - x, 10), Color.White);
        spriteBatch.End();

        spriteBatch.Begin();
        spriteBatch.Draw(texture, new Vector2(x, 100), Color.White);
        spriteBatch.End();

both textures works. But that is so wrong (very unoptimized way to do).

Maybe (hopefully) this helps to find this Android spritebatch draw problem.

I've tested it on my phone it's working fine.

So, in one case it shows the textures black, and in the other case it shows the first texture of the batch but not the second?
Can you tell me what versions did you use for each case?
Last version 3.14 was on Sep 23, 2024. I can't tell what 6.11.2024 is.
If it's Nov 16 2024, then you probably got v3.14 as well. Or was it 3.12 on Jun 11?

Have you tried on other phones?,
and can you give me the specs of your GPU?
If you use 'System Info Droid' and and select 'Email Report' from the menu, it will generate an email. Copy the text here. I am mostly interested in the GPU specs to compare with mine.

"I can't tell what 6.11.2024 is.

Yeah I meant sixth of the november. Cant remember which version of KNI.

But today I tested with different devices (using newest kni nugets like yesterday). Android emulator which starts under VS2022 shows only one black box. Bluestacks shows 2 black boxes.

And then I tested 2 phones:

Phones (both uses Android 10)
Moto e(6i)
Xiaomi Redmi 9A

[bosoni]

1 visible black box is only on that emulator which starts under VS2022 (I just tested and changed coordinates and it only renders 1 black box, other was not out of screen). But all other shows 2 black boxes so there is some little thing wrong.

Under VS2022 debug output shows something maybe important?

and that called unimplemented goes and goes on.

This uses GLES3? On godot 3.6, if I use gles3 and even checked in options fallback to gles2, it does not work because of lowprice phones' graphic drivers. GLES3 works right if using godot 4.x (maybe fallback works then). But That does not solve the issue, that little test does not work even with emulators.

[bosoni]

I just tested Samsung Galaxy A05s (Android 14) and test works right with both images.

[nkast]

Maybe that unimplemented message is a good clue.
From what I see, the emulator doesn't work either. I can test it on the emulator on both my desktop and laptop.
Hopefully I could replicate it on at least one of them and make some tests.

[nkast]

It uses gles3 and fallback to gles2.

[nkast]

@bosoni, I had the same issue with the emulator.
the 'unimplemented OpenGL ES API' come from a call to DrawRangeElementsBaseVertex(...)
Apparently, it returns a function pointer for it instead of null, even though the GLES context is 3.1.

Thanks for reporting, that was a serious bug.
