title: Multiple environment configuration with android xml config on Eclipse
body: <p>My android application could run on multiple environments - dev/test/live.
  I have few config values that are different between the environments (and a lot of values that are the same for all of them).</p>
  
  <p>Is there an easy way to keep a configuration xml file with few states in eclipse, that when changing between them, some of the keys and values will be changed?
  (like DEBUG/RELEASE in .net)</p>
