I want use point sprite (OpenGLES Extension) API in Android NDK(r4). right here int att[] = {0,0,1}; glPointParameterxv( GL_POINT_DISTANCE_ATTENUATION, att );
But, doesn't work it.

Hi,
Functions suffixed with 'xv' and 'x' receives fixed-point data. You can try:
GLFixed[] att = {0, 0, 1 << 16};

I tried it.But, displayed error message like "called unimplemented OpenGL ES API".After all, is not android NDK supported point sprite....?

What does glGetString(GL_EXTENSIONS) say about ARB_point_sprite?

Yes, extension API.It is defined in Android NDK, but displayed "called unimplemented OpenGL ES API" to console.

It is defined in the headers, but that doesn't not mean it's supported by the graphics chip. That's only detectable in runtime, if you call that glGetString function I wrote about.
