title: Android studio .XML confusion with the book that is teaching me android development
body: <p>I have just started my android journey with the help of a book. Which is not recommended but it is my preferred method of learning. In this book when I get to examine the layout file <code>.xml</code> the book says that this pre-made file starts and ends with</p>
  
  <pre><code>&lt;RelativeLayout&gt; ... &lt;/RelativeLayout&gt;
  </code></pre>
  
  <p>but in the android manifest file I was given, I noticed the contents were similar but started and ended with a </p>
  
  <pre><code>&lt;manifest&gt; ... &lt;/manifest&gt;
  </code></pre>
  
  <p>so are these two pieces of code the same, are they interchangeable, how can this confuse me in the future, and can this <em>Error</em> make the book I am using obsolete. (The book is called "Android Programming for Beginners" by John Horton)</p>
