private void draw() { 
     SurfaceHolder holder = getSurfaceHolder(); 
     Canvas canvas = null; 
     try { 
      canvas = holder.lockCanvas(); 
      if (canvas != null) { 

       // Draw background 
       canvas.drawColor(PrefService.getBgColor());         

       StaticLayout textLayout = new StaticLayout(TEXT_I_WOULD_LIKE_TO_ANIMATE, textPaint, screenWidth - screenWidth/8, Layout.Alignment.ALIGN_CENTER, 1.0F, 1.0F, true); 
       canvas.translate((screenWidth/2) - (textLayout.getWidth()/2), (screenHeight/2) - ((textLayout.getHeight()/2))); 
       textLayout.draw(canvas); 
      } 
     } finally { 
      if (canvas != null) {    
        holder.unlockCanvasAndPost(canvas);     
      }
