Re: glGenVertexArrays in Opengl ES 1.0 using android-ndk

check your hardware for gl extensions support I guess.

glGenVertexArrays = (PFNGLGENVERTEXARRAYSOESPROC) eglGetProcAddress("glGenVertexArraysOES");
    glBindVertexArray = (PFNGLBINDVERTEXARRAYOESPROC) eglGetProcAddress("glBindVertexArrayOES");
    glDeleteVertexArrays = (PFNGLDELETEVERTEXARRAYSOESPROC) eglGetProcAddress("glDeleteVertexArraysOES");

    if (!glGenVertexArrays )
            LOGI ( "Can't get proc address: glGenVertexArraysOES" );

    if (glBindVertexArray){
            glBindVertexArray(0);
            LOGI("Vertex array exists");
        }
        else
            LOGI("Vertex array DON'T exists");

Work fine.

But don't work correctly this code =/
glGenVertexArrays(1, &verticesVAO);
    glBindVertexArray(verticesVAO);

What must i write to use Vertex?

if u see no gl extension in list it may be actully supported, but partially.

better late than never :)
eglGetProcAddress() will return NULL for Your code.
You should use
void* libhandle=dlopen("libGLESv2.so",RTLD_LAZY);
glBindVertexArrayOES=(PFNGLBINDVERTEXARRAYOESPROC)dlsym(libhandle,"glBindVertexArrayOES");
//...
