title: What happens to setInterval in react-native after app is in background?
body: <p>I have setup a timer to refresh the screen every 5 minutes. </p>
  
  <pre><code>componentWillMount() {
    this.handle = setInterval(() =&gt; this.props.refreshData(), 300000);
    this.props.refreshData();
  }
  </code></pre>
  
  <p>In componentWillUnmount, I clear the handle.</p>
  
  <pre><code>componentWillUnmount() {
    clearInterval(this.handle);
  }
  </code></pre>
  
  <p>What happens to the timer when the app moves to background? Will it be paused automatically? Or will it continue to run even if the app is in the background? Thanks.</p>
