If I have custom renderer in opengl-es prepared:

public void onDrawFrame(GL10 gl)
{
    gl.glClear(GL10.GL_COLOR_BUFFER_BIT | GL10.GL_DEPTH_BUFFER_BIT);
    // here i want to draw line from [0, 0, 0] to [1, 0, 0]
}

What is the easiest and shortest way to draw line?

In ordinary OpenGL it is:

glBegin(GL_LINES);
    glVertex3f(0, 0, 0);
    glVertex3f(1, 0, 0);
glEnd();

But how can i get the same effect with OpenGL ES?
