    text
    copied!<p>I have two tabs hosted in my Main Activity (I use ActionBarSherlock). My fragments load and parse a distant xml to populate the listview.</p> <p>If I change the device orientation when fragment is fully loaded, it loads again without problem with the new orientation. But if I change it while the fragment is loading, the app force closes at the completion of loading.</p> <p>Am I doing something wrong?</p> <pre><code>public class PartOne extends SherlockListFragment{ // All static variables static final String URL = "http://Y.xml"; // XML node keys static final String KEY_ITEM = "item"; // parent node static final String KEY_TITLE = "title"; static final String KEY_CAT = "category"; static final String KEY_DESC = "description"; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); new BackgroundAsyncTask().execute(); } public class BackgroundAsyncTask extends AsyncTask&lt;String, String, ArrayList&lt;HashMap&lt;String, String&gt;&gt;&gt; { @Override protected void onPreExecute() { } @Override protected ArrayList&lt;HashMap&lt;String, String&gt;&gt; doInBackground(String... paths) { ArrayList&lt;HashMap&lt;String, String&gt;&gt; menuItems = new ArrayList&lt;HashMap&lt;String, String&gt;&gt;(); XMLParser parser = new XMLParser(); String xml = parser.getXmlFromUrl(URL); // getting XML if (xml != null) { Document doc = parser.getDomElement(xml); // getting DOM element NodeList nl = doc.getElementsByTagName(KEY_ITEM); // looping through all item nodes &lt;item&gt; for (int i = 0; i &lt; nl.getLength(); i++) { if(i%2 != 1) { // creating new HashMap HashMap&lt;String, String&gt; map = new HashMap&lt;String, String&gt;(); Element e = (Element) nl.item(i); // data to string (to modify them) String titre = parser.getValue(e, KEY_TITLE); String categorie = parser.getValue(e, KEY_CAT); String description = parser.getValue(e, KEY_DESC); // adding each child node to HashMap key =&gt; value map.put(KEY_TITLE, titre); map.put(KEY_CAT, categorie); map.put(KEY_DESC, description); // adding HashList to ArrayList menuItems.add(map); } } } // selecting single ListView item ListView lv = getListView(); lv.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView&lt;?&gt; parent, View view, int position, long id) { // getting values from selected ListItem String name = ((TextView) view.findViewById(R.id.title)).getText().toString(); String cost = ((TextView) view.findViewById(R.id.categ)).getText().toString(); String description = ((TextView) view.findViewById(R.id.desciption)).getText().toString(); // Starting new intent Intent in = new Intent(view.getContext(), SingleMenuItemActivity.class); in.putExtra(KEY_TITLE, name); in.putExtra(KEY_CAT, cost); in.putExtra(KEY_DESC, description); startActivity(in); } }); return menuItems; } protected void onPostExecute(ArrayList&lt;HashMap&lt;String, String&gt;&gt; result) { ListAdapter adapter = new SimpleAdapter(getActivity(), result, R.layout.list_item, new String[] {KEY_TITLE, KEY_DESC, KEY_CAT}, new int[] {R.id.title, R.id.desciption, R.id.categ}); setListAdapter(adapter); } } </code></pre> <p>Log :</p> <pre><code>java.lang.RuntimeException: An error occured while executing doInBackground() at android.os.AsyncTask$3.done(AsyncTask.java:278) at java.util.concurrent.FutureTask$Sync.innerSetException(FutureTask.java:273) at java.util.concurrent.FutureTask.setException(FutureTask.java:124) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:307) at java.util.concurrent.FutureTask.run(FutureTask.java:137) at android.os.AsyncTask$SerialExecutor$1.run(AsyncTask.java:208) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1076) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:569) at java.lang.Thread.run(Thread.java:856) Caused by: java.lang.IllegalStateException: Content view not yet created at android.support.v4.app.ListFragment.ensureList(ListFragment.java:328) at android.support.v4.app.ListFragment.getListView(ListFragment.java:222) </code></pre>
