title: Android shared preferences names
body: <p>I can obtain SharedPreferences via:</p>
  
  <pre><code>getSharedPreferences("someName", ...)
  </code></pre>
  
  <p>How do I get a list of all names of shared preferences in my application?</p>
  
  <p>If it's not possible via code, is there any way to do it via adb (without root)?</p>
