title: Android app shows debug options with release build
body: <p>I build an app with <code>./gradlew assembleRelease</code> and then running this app shows debug options.</p>
  
  <p><em>This is for android app only.</em></p>
  
  <pre><code>cd android &amp;&amp; ./gradlew assembleRelease
  </code></pre>
  
  <p>I expect it will not show debug options but they are shown. </p>
