title: My app version control
body: <p>I was working on my application for android. And as I started it just now i gave the version as <strong>Version 0.01</strong>. and <strong>hard coded it in string.xml</strong> which is used in linear layout. </p>
  
  <p>Now <strong>my question is</strong>: do android provide some method so that instead of hard coding the version no., android provide this. And when I want to update the version it is easily updated. If android does not provide such thing , <strong>is there some way through which I save myself from hard coding it</strong>.</p>
  
  <p>Thanks in advance. </p>
