title: Cant get gradient backgrounds to look good?
body: <p>I've tried everything, and searched the whole web, but still, nothing works.<br>
  Here is the background my designer designed:<br>
   <img src="https://i.stack.imgur.com/vAGZp.jpg" alt="enter image description here"></p>
  
  <p>And here how it looks on my screen (Galaxy S I9000):<br>
  <img src="https://i.stack.imgur.com/Rgp3V.png" alt="enter image description here"></p>
  
  <p>I've tried to enable dithering with this code:  </p>
  
  <pre><code>findViewById(R.id.LinearLayout_Main).getBackground().setDither(true);
      @Override
  public void onAttachedToWindow() {
      super.onAttachedToWindow();
      Window window = getWindow();
      window.setFormat(PixelFormat.RGBA_8888);
  }
  </code></pre>
  
  <p>Can anyone tell me why?</p>
