boolean drawGlow = false;
//this is the pixel coordinates of the screen
float glowX = 0;

//this is the radius of the circle we are drawing
float radius = 20;
//this is the paint object which specifies the color and alpha level 
//of the circle we draw
Paint paint = new Paint();

@Override
public void draw(Canvas canvas){

    if(drawGlow)
        canvas.drawCircle(glowX, glowY, radius, paint);
}
@Override
public boolean onTouchEvent(MotionEvent event){
