title: what's wrong with hardcoded string in android xml file?
body: <p>I love to put simple text directly on the xml file without declaring a string first. It is easier, more simple and less messy. However, it always has a warning badge whenever I do so.</p>
  
  <p>What if I have a dozens of hardcoded string in my xml file without concerning the warning? Will I get into a trouble?</p>
  
  <p>thanks in advance.</p>
