title: Android Studio Build Errors after 9 Patch pngs Added to res/drawable
body: <p>After using Android Studio's 9-patch generation tool to make a few 9 patch pngs, I get the following build errors when I try to run:
  <code>Error:java.util.concurrent.ExecutionException: com.android.ide.common.process.ProcessException:</code></p>
  <p>I've tried running <code>clean</code>, <code>build</code>,  and <code>Invalidate Caches / Restart</code> and I cant get this error to resolve! When I delete the 9 patch image from my drawable/no-dpi folder and re-add the original non-9-patch png the code compiles and runs fine. How do I fix this error?<a href="https://i.stack.imgur.com/W61Q7.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/W61Q7.png" alt="enter image description here" /></a></p>
  <p><strong>Edit</strong>
  Using a different 9 patch image worked, so the problem seems to be with my 9 patch image I created. What's wrong with it? I want the text &quot;Capo&quot; to not stretch when the button is laid out vertically so I tried to make stretchy areas between that part of the image and the corners (which also shouldn't stretch).</p>
