    <p>In my app I try to save ArrayList state with putSerializable method in onSaveInstanceState. And restore it in onCreate and onRestoreInstanceState. In my app if there is no saved instance of this object it will be create from internet data. But all the time I try to test this solution ArrayList start to downloading from network. Can anyone help me?</p> <pre><code>public class Activity extends SherlockActivity { ListView listView; SlidingMenu slidingMenu; ArrayList&lt;HashMap&lt;String, String&gt;&gt; newsList = null; String url = "/////here_my_url////"; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); getActionBar().setDisplayHomeAsUpEnabled(true); getActionBar().setTitle(R.string.news_vatican); listView = (ListView) findViewById(R.id.newslist); slidingMenu = new SlidingMenu(this); slidingMenu.setMode(SlidingMenu.LEFT); slidingMenu.setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN); slidingMenu.setFadeDegree(0.35f); slidingMenu.attachToActivity(this, SlidingMenu.SLIDING_CONTENT); slidingMenu.setMenu(R.layout.slidingmenu); slidingMenu.setBehindOffset(150); if (savedInstanceState != null){ newsList = (ArrayList&lt;HashMap&lt;String, String&gt;&gt;) savedInstanceState.getSerializable("list"); Log.e("Activity", "RESTORING"); } else { Log.e("Activity", "PARSING NEW"); JSONParser parser = new JSONParser(this); parser.execute(url); try { newsList = parser.get(); } catch (InterruptedException e) { e.printStackTrace(); Log.e("Activity", "Failed to get newslist"); } catch (ExecutionException e) { e.printStackTrace(); Log.e("Activity", "Failed to get newslist"); } } listView.setAdapter(new NewsAdapter(getApplicationContext(), newsList)); } @Override protected void onSaveInstanceState(Bundle savedInstanceState) { savedInstanceState.putSerializable("list", newsList); super.onSaveInstanceState(savedInstanceState); } @Override protected void onRestoreInstanceState(Bundle savedInstanceState) { super.onRestoreInstanceState(savedInstanceState); newsList = (ArrayList&lt;HashMap&lt;String, String&gt;&gt;) savedInstanceState.getSerializable("list"); } </code></pre>

    1. COThere is a difference between restoring state and persisting data. Is the ArrayList downloaded again even when you rotate the device from portrait to landscape(or vice versa)?

    3. COWell, in that case, `onSaveInstanceState(Bundle)` is kind of useless for you. What you need is a way to persist data across subsequent launches. Am I correct?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
