title: Android Studio says I'm not on gradle build, but I am
body: <p>So I've just imported an app into Android Studio. It says </p>
  
  <pre><code>"Migrate Project to Gradle? This project does not use the Gradle build 
  system. We recommend that you migrate to using the Gradle build system."
  </code></pre>
  
  <p>However... it appears I am on the gradle system. I see </p>
  
  <pre><code>build.gradle
  </code></pre>
  
  <p>files at the app-level etc, so? This is causing issues when I try to run the module (getting AndroidManifest.xml does not exist error, which I apparently need to solve by synching the gradles... except that button doesn't exist because Android Studio thinks I'm not using the gradle system.)</p>
  
  <p>Help?</p>
