title: Android Paint PorterDuff.Mode.CLEAR drawing black color on my view
body: <p>I want to implement eraser for my painting app . I am able to erase with the following code </p>
  
  <pre><code> paint.setColor(0x00000000);
   paint.setAlpha(0x00);
  </code></pre>
  
  <p>But after erasing when you start painting again it does not paint properly so any idea to erase paint please suggest.</p>
