title: 9-patch image error in Android
body: <p>Whenever I try to add a 9-patch image to the <code>\drawable</code> folder in my project, I get the same error:</p>
  
  <pre><code>ERROR: 9-patch image C:\...\res\drawable\appwidget.9.png malformed.
  Frame pixels must be either solid or transparent (not intermediate alphas).
  Found at pixel #3 along top edge. Failure processing PNG image
  C:\...\res\drawable\appwidget.9.png
  </code></pre>
  
  <p>The weird thing in this example is that I've got this image from the "android-g1-icon" images found in the SDK resources, so it is supposed to be OK. The same happened with any 9-patch image I've tried so far. What could be wrong?</p>
