title: React Native: always gradlew clean before run react-native-run-android
body: <p>If don't run <code>cd android &amp;&amp; ./gradlew clean</code> before <code>react-native run-android</code> this fails with some error like: </p>
  
  <blockquote>
    <p>Failed to create folder: ...</p>
  </blockquote>
  
  <p>or</p>
  
  <blockquote>
    <p>Failed to delete folder: ...</p>
  </blockquote>
  
  <p>so I must run more times again to solve it.</p>
  
  <p>Help me solve it without <code>gradlew clean</code>, please.</p>
  
  <p>Thanks so much.</p>
