examples don't work in android webgl enabled browser about three.dart HOT 10 CLOSED

Android built in browser or Chrome on android? If its the built in browser I have little hope anything works in it.

from three.dart.

Can you specify exactly which android version, device, browser and browser version. Helps get an idea of the env you talking about.

from three.dart.

Cyanogenmod (android 4.2.2) on nexus 7 using chrome 27.0.1453.90
Not the default browser

Interesting, I had a similar setup at one point and chrome did work.

from three.dart.

its a pity it should just "run anywhere" (tm) (c) after all it should just
fall back to js and I know webgl works fine on it

Did you build the examples yourself or are you using the prebuilt ones from the project's site?

from three.dart.

from the site, I also attempted a simple dart webgl example I threw
together without joy, why they fail is a mystery to me - its just JS and
webgl so it should just work ? - I don't think this is a three.dart
specific issue

Real shame dart/webgl doesn't seem to just work everywhere ... :(

@financecoding I was looking into this and the problem seems to be in the shader compilation.
The compile status is true but for some weird reason !_gl.getShaderParameter( shader, gl.COMPILE_STATUS )
evaluates to true so the shader is set to null!
Can you please test it to see if you can reproduce it ? you can just remove the test and you'll see that the program runs just fine.

I added some simple debug code:

var success = _gl.getShaderParameter( shader, gl.COMPILE_STATUS );
print(success);
if (success) { print("It's true");}
if (!success) { print("It's false");}

And i get:
true
It's false

from three.dart.

While the getShaderParameter test is undoubtedly causing an issue in general with JS compiled apps (see #89), removing it doesn't get the examples working on Android Chrome.

There's definitely another issue at play here, since they work OK on Android Firefox and Opera. Also, the Three.js examples work on Android Chrome so the issue is specific to Three.dart on Android Chrome.

@nelsonsilva what does print(success.runtimeType); print out? Sounds like idl mismatch of some sort.
