build.xml:266: null returned: 3

in Android Processing • 1 year ago

I've just started programming for android and thought of using Processing as it would speed up the learning process. I've installed everything required and can run all examples besides the OpenGL. But all I need is OpenGL, I can run all other examples in the emulator and on my htc tablet but cant get anything with OpenGL to work.

This is the error:

BUILD FAILED
C:\Program Files (x86)\Android\android-sdk\tools\ant\build.xml:851: The following error occurred while executing this line:
C:\Program Files (x86)\Android\android-sdk\tools\ant\build.xml:853: The following error occurred while executing this line:

C:\Program Files (x86)\Android\android-sdk\tools\ant\build.xml:266: null returned: 3
Total time: 8 minutes 29 seconds

I'm using Processing 2.0a6, Windows 7 64bit and using API 10 for Android 2.3.3. I've tried other versions but they've resulted in other errors.

I've reinstalled ANT, SDK, Processing, the lot to no avail. Is Opengl part of the processing core or do I need to move some libraries around to get it to work? Am I required to modify the build file even though it's an example?

Any help would be greatly appreciated.

Android development, especially with the latest version of Processing, is particularly buggy...
What example, specifically, are you using? I'd like to see if I can duplicate your error...
Unfortunately, there probably isn't going to be a solution... for right now, at least.

Well its any drawing example from opengl.

void setup() {
size(240, 400, A3D);
stroke(255, 150);
}
void draw() {
background(0);
translate(50, 50, 0);
noStroke();
fill(255, 200);
rect(60, 0, 100, 100);
}

Taken from:

http://users.design.ucla.edu/~acolubri/files/Fast3DGraphics.pdf

Results in the same error:

C:\Program Files (x86)\Android\android-sdk\tools\ant\build.xml:680: The following error occurred while executing this line:
C:\Program Files (x86)\Android\android-sdk\tools\ant\build.xml:693: Compile failed; see the compiler error output for details.

Instead of A3D I've tried A2D and opengl but none of them work.

Hold on, I'm still trying to look into it... unfortunately, my ant installation appears to have become corrupt and I can't run anything...

I remember there being a couple of posts about 3D with Android, none of which worked in the end. You may be out of luck.

I dont even need to compile 3D code all I require is 2D drawing. I have some windows opengl C++ code which I want to port over to android. All it is is drawing 2D shapes, rotations and translations.

So... you want to port over 2D drawing that uses OpenGL...
Do you need OpenGL for it to work? Can you try to use standard 2D first?

It must have a high frame rate and so I decided to use opengl, im not sure what the frame rate is when not using opengl on android. The drawing is moderately complex with 1000+ polygons.

Okay... put simply: I don't think you're going to have any luck with OpenGL.
Andres Colubri might have more to say about it...
