title: java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Boolean
body: <p>I am trying to get and set a boolean through Sharedpreferences. The following code perfectly works on Marshmallow but not on Lolipop (5.0.1) - I get an exception: java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Boolean when I call getintroStatus()</p>
  
  <p>Any help?</p>
  
  <pre><code>public void setIntrodone(boolean status) {
          editor = settings.edit();
          editor.putBoolean("intro_done_boolean", status);
          editor.commit();
      }
  
      public boolean getintroStatus() {
          try {
              return settings.getBoolean("intro_done_boolean", false);
          } catch (Exception e) {
              e.printStackTrace();
              return false;
          }
  
      }
