title: Distinguishing development mode and release mode environment settings on Android
body: <p>I'm building an Android application and would like to maintain a few environment variables that I can tweak depending on whether I'm in development mode or release mode. For example, I need to invoke a web service and the URL will be slightly different in either mode.  I'd like to externalize this and other settings so I can change them easily based on my target deployment.</p>
  
  <p>Are there any best practices or anything in the SDK to assist with this need?</p>
