title: Android studio strange warning
body: <p>I'm new to code in Android Studio and when i set a integer in a text like this:</p>
  
  <pre><code>textview.setText(String.format("%d",1));
  </code></pre>
  
  <p>This code give me back a warning:</p>
  
  <blockquote>
    <p>Implicitly using the default locale is a common source of bugs: Use String.format (Locale,...)</p>
  </blockquote>
  
  <p>What is the correct code for put an integer in a .setText?</p>
  
  <p>I founded more question on stackoverflow but don't apply to this.</p>
