glDrawElements crashing on devices, working well on emulator

I've been spending my time with OpenGL-ES over android. Everything goes well, I'm making a 2D game, I can display sprites on the screen, move them, etc etc. But all that just works on the emulator. On my Motorola Droid 1, it just close (even without the forceclose warning).

The debugger did not throws anything, nor send debug text, so I stopped at some lines and gone with step into and step over until reach the place that the app suddenly closes.

The result is, it closes in this line:

gl.glDrawElements(GL10.GL_TRIANGLES, 6, GL10.GL_UNSIGNED_SHORT, indices);

To help, this is my full drawing function:

    /**
 * Draw the sprite on the screen
 * @param gl OpenGLES Context
 */
public void draw(GL10 gl, Vector3 position){
    if(textured)
        gl.glBindTexture(GL10.GL_TEXTURE_2D, textureName);

    gl.glPushMatrix();
        gl.glLoadIdentity();
        gl.glTranslatef(position.X, position.Y, position.Z);
        gl.glScalef(scale.X, scale.Y, 1);
        gl.glRotatef(rotation.X, 1.0f, 0.f, 0.0f);
        gl.glRotatef(rotation.Y, 0.0f, 1.0f, 0.0f);
        gl.glRotatef(rotation.Z, 0.0f, 0.0f, 1.0f);

        gl.glVertexPointer(3, GL10.GL_FLOAT, 0, vertices);

        if(textured)
            gl.glTexCoordPointer(2, GL10.GL_FLOAT, 0, uvs);

        //gl.glColorPointer(4, GL10.GL_FLOAT, 0, colors);

        gl.glDrawElements(GL10.GL_TRIANGLES, 6, GL10.GL_UNSIGNED_SHORT, indices);
    gl.glPopMatrix();
}

I have no clues about what makes this, because it works very well, display my sprites and so on the emulator, but closes on the device.

Here's the logcat log:

Any hints, please?

EDIT:

As mentioned by Spoon Thumb, here are my enable/disable calls:

gl.glClear(GL10.GL_COLOR_BUFFER_BIT | GL10.GL_DEPTH_BUFFER_BIT);

gl.glEnableClientState(GL10.GL_VERTEX_ARRAY);
gl.glEnableClientState(GL10.GL_TEXTURE_COORD_ARRAY);

for (Drawable i : toDraw) {
    i.draw(gl);
}

gl.glDisableClientState(GL10.GL_VERTEX_ARRAY);
gl.glDisableClientState(GL10.GL_TEXTURE_COORD_ARRAY);

these are on the onDrawFrame. it calls the drawable.draw, that are the first function i have posted.

If it would help, this is my onSurfaceChanged with my enables and disables:

public void onSurfaceChanged(GL10 gl, int width, int height) {
gl.glViewport(0, 0, width, height);
gl.glMatrixMode(GL10.GL_PROJECTION);
gl.glLoadIdentity();
gl.glOrthof(0.0f, width, 0.0f, height, 0.0f, 1.0f);

gl.glShadeModel(GL10.GL_FLAT);
gl.glEnable(GL10.GL_BLEND);
gl.glEnable(GL10.GL_TEXTURE_2D);
gl.glBlendFunc(GL10.GL_SRC_ALPHA, GL10.GL_ONE_MINUS_SRC_ALPHA);

gl.glMatrixMode(GL10.GL_MODELVIEW);
gl.glLoadIdentity();
}

ALSO, i have edited the code a little, dont have sure about i changed, but now i dont receive a SIGSEGV 11, the code runs on my device, but i cant see nothing.

I managed to make this work by myself.

I don't know EXACTLY what I did, but it stopped crashing when:

Changed glDrawElements to glDrawArray

Well, to make this I had to change all the way that I built my quads, and now, I don't use indices anymore (though I should be using).

Changed:

gl.glDrawElements(GL10.GL_TRIANGLES, 6, GL10.GL_UNSIGNED_SHORT, indices);

to:

gl.glDrawArrays(GL10.GL_TRIANGLE_STRIP, 0, 4);

Don't forget to point your vertices array.

Enable and disable Clientstates for every draw, not once per frame.

Instead of:

gl.glEnableClientState(GL10.GL_VERTEX_ARRAY);
gl.glEnableClientState(GL10.GL_TEXTURE_COORD_ARRAY);

drawspriteone();
drawspritetwo();
drawspriteN();...

gl.glDisableClientState(GL10.GL_VERTEX_ARRAY);
gl.glDisableClientState(GL10.GL_TEXTURE_COORD_ARRAY);

I had to do this INSIDE of the draw function, like this:

gl.glBindTexture(GL10.GL_TEXTURE_2D, texture.id);

gl.glVertexPointer(3, GL10.GL_FLOAT, 0, vertices);
gl.glEnableClientState(GL10.GL_VERTEX_ARRAY);
gl.glTexCoordPointer(2, GL10.GL_FLOAT, 0, uvs);
gl.glEnableClientState(GL10.GL_TEXTURE_COORD_ARRAY);

gl.glDrawArrays(GL10.GL_TRIANGLE_STRIP, 0, 4);

gl.glDisableClientState(GL10.GL_VERTEX_ARRAY);
gl.glDisableClientState(GL10.GL_TEXTURE_COORD_ARRAY);

Ah, try enabling and disabling textures inside of each draw too.

I don't know which of these changes made the app work on my phone, but it even though now it was running, it still wouldn't draw anything. Yes, I could see the buffer clear color, but no textures.

What did I do?

Well, it was a lot of trial and error, some research lead me to think that the GPU of Milestones (it's the European/South American version of Moto Droid) and some other devices has a OpenGL driver that works quite different, and they don't support changing the color format. Maybe that can be true, but it wasn't the case.

I changed the orders of the calls, set states, etc. But my error was so, so, so silly, that I could find it just today.

Let's cut to the answer:

DRAW 2D QUADS ON THE 0.0f Z COORD!

Why? I don't know. But, my Z coord of every sprite was set to 0.1f, I changed them and now I can see all the sprites. Strange huh? Even stranger: the emulator COULD see the textures with the z set to 0.1f, but the device didn't..

Just to let you know, this was my viewport setting:

gl.glOrthof(0.0f, width, 0.0f, height, 0.0f, 1.0f);

nearplane as 0.0f and farplane as 1.0f. Shouldn't it accept values between 0.0f and 1.0f?

Thanks! that's the final answer to my question (:

My program crashed while use gl.glDrawElements().

I find the reason is the code:

byteBuffer = ByteBuffer.allocate(6 * 2);

The work well one:

byteBuffer = ByteBuffer.allocateDirect(6 * 2);
byteBuffer.order(ByteOrder.nativeOrder()); 
indices = byteBuffer.asShortBuffer();
indices.put(new short[]{2, 0, 1, 1, 3, 2}); 
indices.flip();

Here's the error logcat log:

You haven't got any enable/disable calls. Try adding at the top of your onDraw method:

    gl.glEnableClientState(GL10.GL_VERTEX_ARRAY);


    if(textured){
        gl.glEnableClientState(GL10.GL_TEXTURE_COORD_ARRAY);
    }

and then after glDrawElements():

    if(textured){       
        gl.glDisableClientState(GL10.GL_TEXTURE_COORD_ARRAY);
    }

    gl.glDisableClientState(GL10.GL_VERTEX_ARRAY);

failing that, try putting a try/catch block around the glDrawElements() line and/or turn on debugging in your GLSurfaceView:

glDrawElements crashing on devices, working well on emulator

Answers (3)

Changed glDrawElements to glDrawArray

Enable and disable `Clientstates` for every draw, not once per frame.

Ah, try enabling and disabling textures inside of each draw too.
