title: Why is my Android background color not visible?
body: <p>I'm trying to figure out one simple thing: how to set a background color in Android view. Here is the code in an Activity:</p>
  
  <pre><code>public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
  
      View v = new  View(this);
  
      setContentView(v);
      v.setBackgroundColor(23423425);
  }
  </code></pre>
  
  <p>and all I get is black screen.</p>
