title: Extract all hardcoded strings to string resource
body: <p>I know there is <kbd>Alt</kbd> + <kbd>Enter</kbd> combination to extract single String to string resource. But I am wondering is there anything that I can extract all string of my project into string resource?</p>
  
  <p>Also Android studio not making same String to string resource if I make one of them. </p>
  
  <pre><code>String s = "Hello World";
  String s2 = "Hello World";
  </code></pre>
  
  <p>For example. I make "Hello World" to string resource still another remain Hardcoded in same file as well in the project too.</p>
  
  <pre><code>String s = getString(R.string.helloworld);
  String s2 = "Hello World";
  </code></pre>
  
  <p>If anyone know something like that.</p>
