title: Android: looking for a drawArc() method with inner & outer radius
body: <p>I have the following custom view:</p>
  
  <p><img src="https://i.stack.imgur.com/boJS4.png" alt="alt text"></p>
  
  <p>This I have achieved by using the Canvas' <code>drawArc()</code> method. However, with this <code>drawArc()</code> method I cannot limit the arc's inner radius.</p>
  
  <p>What I'd like to have is something like this:</p>
  
  <p><img src="https://i.stack.imgur.com/c1eqe.png" alt="alt text"></p>
  
  <p>where there is only an outer ring left.</p>
  
  <p>What I need is an <code>drawArc()</code> function where I can set the inner radius of the arc. Anyone an idea how to do that?</p>
  
  <p>(BTW, overpainting the inner area doesn't work, because it needs to be transparent. Painting an inner circle with <code>Color.TRANSPARENT</code> after painting the red and blue cones doesn't remove the old color. It just puts another layer on top, which is transparent and through which I can still see the red and blue)</p>
