title: What is the preferable way to hide private information in Android Studio?
body: <p>I want to hide private information like API key when uploading my project. So I am wondering if there's a way to set environment variable somewhere as I do in command prompt. </p>
  
  <p>For example, I want to hide my API key in <code>google_maps_api.xml</code></p>
  
  <pre><code>&lt;string name="google_maps_key" templateMergeStrategy="preserve" translatable="false"&gt;API_KEY_HERE&lt;/string&gt;
  </code></pre>
  
  <p>How can I do it in Android Studio?</p>
