title: QT Creator wont list any available Android Build SDKs
body: <p>When attempting to build and run an example project with QT Creator, it fails, saying:</p>
  
  <pre><code>Build failed
  Warning: Android platform 'android--1' does not exist in SDK.
  Building the android package failed!
  </code></pre>
  
  <p>All the solution I have found say to select the appropriate Android build SDK in the Build Android APK, however the dropdown for that option is grayed out:</p>
  
  <p><a href="https://i.stack.imgur.com/i6fbq.png" rel="noreferrer">Empty Android build SDK dropdown</a></p>
  
  <p>When looking into this, the only solution I can find is people saying to make sure my JDK, SDK, and NDK paths were put into the <code>Tools &gt; Options &gt; Devices &gt; Android</code> area, which I'd already done:</p>
  
  <p><a href="https://i.stack.imgur.com/zeeOR.png" rel="noreferrer">SDK Path</a> </p>
  
  <p>Haven't really been able to find what else could be causing the problem. Any ideas on where to go from here would be most appreciated.</p>
