Before posting here, I googled this issue, and did find one other
unsolved thread about this same issue.
If anyone else comes here after googling, here's information about
what happened between it not working and working:
(I'm not sure which of these steps is what fixed it, and I don't
intend to find out :))
I got rid of everything GL11 (everything is GL10 now).
I changed my LoadTexture function from:
int LoadTexture(int resID,GL10 gl){
Resources res = gp.getContext().getResources();
Bitmap bmp = BitmapFactory.decodeResource(res,resID);
int[] tmp_tex = new int[1];
gl.glGenTextures(1, tmp_tex, 0);
int tex = tmp_tex[0];
gl.glBindTexture(GL10.GL_TEXTURE_2D, tex);
gl.glTexParameterf(GL10.GL_TEXTURE_2D,
GL10.GL_TEXTURE_MIN_FILTER, GL10.GL_LINEAR);
gl.glTexParameterf(GL10.GL_TEXTURE_2D,
GL10.GL_TEXTURE_MAG_FILTER, GL10.GL_LINEAR);
gl.glTexParameterf(GL10.GL_TEXTURE_2D,
GL10.GL_TEXTURE_WRAP_S,GL10.GL_CLAMP_TO_EDGE);
gl.glTexParameterf(GL10.GL_TEXTURE_2D,
GL10.GL_TEXTURE_WRAP_T,GL10.GL_CLAMP_TO_EDGE);
gl.glTexParameterf(GL10.GL_TEXTURE_2D,GL10.GL_ALPHA,
GL10.GL_ALPHA_BITS);
GLUtils.texImage2D(GL10.GL_TEXTURE_2D, 0, bmp, 0);
bmp.recycle();
return tmp_tex[0];
}
to
int LoadTexture(int resID,GL10 gl)
{
int[] textures = new int[1];
gl.glGenTextures(1, textures, 0);
int mTextureID = textures[0];
gl.glBindTexture(GL10.GL_TEXTURE_2D, mTextureID);
gl.glTexParameterf(GL10.GL_TEXTURE_2D,
GL10.GL_TEXTURE_MIN_FILTER,GL10.GL_NEAREST);
gl.glTexParameterf(GL10.GL_TEXTURE_2D,GL10.GL_TEXTURE_MAG_FILTER,GL10.GL_LINEAR);
gl.glTexParameterf(GL10.GL_TEXTURE_2D,
GL10.GL_TEXTURE_WRAP_S,GL10.GL_CLAMP_TO_EDGE);
gl.glTexParameterf(GL10.GL_TEXTURE_2D,
GL10.GL_TEXTURE_WRAP_T, GL10.GL_CLAMP_TO_EDGE);
gl.glTexEnvf(GL10.GL_TEXTURE_ENV,
GL10.GL_TEXTURE_ENV_MODE,GL10.GL_REPLACE);
InputStream is =
gp.getContext().getResources().openRawResource(resID);
Bitmap bitmap;
try {
bitmap = BitmapFactory.decodeStream(is);
} finally {
try {
is.close();
} catch(IOException e) {
// Ignore.
}
}
GLUtils.texImage2D(GL10.GL_TEXTURE_2D, 0, bitmap, 0);
bitmap.recycle();
return mTextureID;
}
}
(I found the body of this in the ApiDemo with the 3 letters on a
textured triangle spinning).
Only a few differences, but they are there.
Again, I'm not sure which of those two things is what fixed it (and
it's even possible that it was something else that I don't remember
doing).
Hopefully this helps someone else.
(and thanks to R. Green for testing it on his Droid).
