title: Android onCreate() not working
body: <p>I'm having a strange problem to do with stopping my android app. On my phone I have a home button and a back button, now when I go into my app after pressing the home button, the program loads data from the internet as expected, but when I go into my app after pressing the back button, the data doesn't load. I've debugged it to an extent, and have found out that the only difference is that the back button calls the onCreate() method. I'm quite confused to why this is is happening.</p>
  
  <p>Here's some of my code: </p>
  
  <pre><code>protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
  
          Log.d("DAP", "Created");
  
          setContentView(R.layout.activity_ltc);
  
          getActionBar().setTitle("LTC Charts");
          getActionBar().setLogo(
                  getResources().getDrawable(R.drawable.new_litecoin_logo_large));
  
          TextView textView = (TextView) findViewById(R.id.ltcdata);
          textView.setText("Loading data...");
  
          TimerTask timer = new TimerTask() {
  
              @Override
              public void run() {
  
                  parseJSON();
              }
  
          };
  
          Timer time = new Timer();
          time.schedule(timer, 500, 85);
  
      }
  </code></pre>
