title: Delete all shared preferences of my Application
body: <p>Is there a nice way to delete all SharedPreferences (= all data from all key to value maps, not just all values from a single map) of my application programmatically on Android? There were similar questions here, but I really want to delete <strong>all</strong>, not just "OneOfMany", so</p>
  
  <pre><code>SharedPreferences settings = context.getSharedPreferences("OneOfMany", Context.MODE_PRIVATE);
  settings.edit().clear().commit();
  </code></pre>
  
  <p>is not good solution.</p>
  
  <p>And <strong>programmatically</strong> means that Application manager/My app/Clear data is also not good solution. Any idea?</p>
