title: difference in naming xml between res-auto and com.package.name - android
body: <p>I have seen custom xml with :</p>
  
  <pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:custom="http://schemas.android.com/apk/res-auto"
  </code></pre>
  
  <p>and  </p>
  
  <pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:custom="http://schemas.android.com/apk/com.package.custom"
  </code></pre>
  
  <p>whats the difference between these two separate names? </p>
  
  <ol>
  <li>Is the latter only points to default location like your package?</li>
  <li>Is the former points to the reference lib ?</li>
  </ol>
  
  <p>thanks.</p>
