title: How to modify IP & port use react-native Android?
body: <p>I used the react-native Android demo project AwesomeProject and within the project I executed:</p>
  
  <pre><code>react-native start
  </code></pre>
  
  <p>In a second terminal:</p>
  
  <pre><code>react-native run-android
  </code></pre>
  
  <p>To start webserver and install the Android APK. The default webserver configuration is localhost:8081, how can I modify the webserver port, and how do I update recording of the IP &amp; Port in Android project.</p>
  
  <p><strong>Edit:</strong> </p>
  
  <p>I just found out that can modify ip address in Android debug setting, it seems "getDebugServerHost" is a private API, does Facebook provide any API to change ip&amp;port?</p>
