title: Changed the name of my Activity java file, how do I update xml reference?
body: <p>So I decided to rename a few of my java classes with the refactor tool. It didn't however update the references in my XML files. I tried changing the reference manually by changing</p>
  
  <p>from</p>
  
  <pre><code>    tools:context=".SomethingElse"&gt;
  </code></pre>
  
  <p>to</p>
  
  <pre><code>    tools:context=".CarbInput"&gt;
  </code></pre>
  
  <p>"CarbInput.java" is the new class name. And SomethingElse.java was the old class name.</p>
  
  <p>This does not work. I can't find another reference to the java file inside the xml. </p>
  
  <p>What am I missing?</p>
  
  <p>Clarification : I am working in Android Studio</p>
