title: How to use SharedPreferences
body: <p>I'm new to android development - using a book called Sams Teach Yourself Android Application Development in 24 hours. Followed it so far but got stuck trying to use SharedPreferences. </p>
  
  <p>In the folder src/com.androidbook.triviaquiz I've got a file called QuizActivity, in it I've got the following:</p>
  
  <pre><code>package com.androidbook.triviaquiz;
  
  import android.app.Activity;
  import android.os.Bundle;
  import android.content.SharedPreferences;
  public class QuizActivity extends Activity {
  
      public static final String GAME_PREFERENCES = "GamePrefs";
      SharedPreferences settings = getSharedPreferences(GAME_PREFERENCES, MODE_PRIVATE);
      SharedPreferences.Editor prefEditor = settings.edit();
      prefEditor.putString("UserName", "JaneDoe");
      prefEditor.putInt("UserAge", 22);
      prefEditor.commit();
  }
  </code></pre>
  
  <p>This is what the book tells me to use, but it returns errors at the following points:
      under the "." after the first 2 prefEditor statements,
      under ("UserName", "JaneDoe")
      under ("UserAge", 22);
      and under "commit"</p>
  
  <p>I've looked on loads of websites for help but all seem to use the same code. What am I doing wrong?</p>
