title: What's the effective risk of using deprecated methods on Android platform?
body: <p>I created a project using an old version of Android (2.2). Now I refreshed the project and I'm using the last version (4.x). I see a lot of warnings about method deprecation, for example: <code>addPreferencesFromResource()</code>.</p>
  
  <p>What is the effective risk on perpetuating the use of <code>addPreferencesFromResource()</code> in my code?</p>
