    <p>Time to time users get following exception (I myself can't reproduce it):</p> <pre><code>java.lang.IllegalStateException: The content of the adapter has changed but ListView did not receive a notification. Make sure the content of your adapter is not modified from a background thread, but only from the UI thread. [in ListView(2131165209, class android.widget.ListView) with Adapter(class com.tfd.mobile.TfdSearch.TfdSearch$SearchList$PagesListAdapter)] at android.widget.ListView.layoutChildren(ListView.java:1567) at android.widget.AbsListView.onTouchModeChanged(AbsListView.java:2093) at android.view.ViewTreeObserver.dispatchOnTouchModeChanged(ViewTreeObserver..java:591) at android.view.ViewRoot.ensureTouchModeLocally(ViewRoot.java:2023) at android.view.ViewRoot.ensureTouchMode(ViewRoot.java:2007) at android.view.ViewRoot.handleMessage(ViewRoot.java:1775) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:123) at android.app.ActivityThread.main(ActivityThread.java:4633) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:521) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:858) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:616) at dalvik.system.NativeStart.main(Native Method) </code></pre> <p>I can't find why it happened. I use threading, but all underlying data changes in main thread. And I'm always call _adapter.notifyDataSetChanged(); after data has been changed. Please help me! This is my code:</p> <pre><code> private class SearchList extends LinkedList&lt;PageInfo&gt; { private static final long serialVersionUID = 1L; private PagesListAdapter _adapter; public PagesListAdapter getAdapter() { return _adapter; } public SearchList(ListView listView) { super(); _adapter = new PagesListAdapter(activity, this); listView.setAdapter(_adapter); } private void getSuggestions(final String typedText) { showProgressVisibility(true); new Thread(new Runnable() { public void run() { android.os.Process.setThreadPriority(android.os.Process.THREAD_PRIORITY_BACKGROUND); final String[] sugg = TfdMode.getMode().getSuggestions(typedText); activity.runOnUiThread(new Runnable() { public void run() { if (sugg != null) { clear(); for (String s: sugg) { add(new PageInfo(s, PageInfo.PAGE_SUGGESTION, null)); } } _adapter.notifyDataSetChanged(); showProgressVisibility(false); } }); } }).start(); } public void refresh(final String typedText) { if (typedText.length() &gt;= 3) { // use suggestions (separate thread) getSuggestions(typedText); } else { // use recent clear(); for (PageInfo p: TfdMode.getMode().recentManager.pages) { if (p.text.startsWith(typedText)) add(p); } if (size() == 0 &amp;&amp; typedText.length() &gt; 0) getSuggestions(typedText); // if no recent - use suggestions else _adapter.notifyDataSetChanged(); } } public class PagesListAdapter extends ArrayAdapter&lt;PageInfo&gt; { private LayoutInflater mInflater; public PagesListAdapter(Context context, List&lt;PageInfo&gt; objects) { super(context, R.layout.bookmarks_item, R.id.bookmark_title, objects); mInflater = (LayoutInflater) context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE); } @Override public View getView(int position, View convertView, ViewGroup parent) { final PageInfo b = getItem(position); View row = convertView == null ? mInflater.inflate(R.layout.bookmarks_item, null) : convertView; TextView title = (TextView) row.findViewById(R.id.bookmark_title); ImageView img = (ImageView) row.findViewById(R.id.bookmark_img); ImageView del = (ImageView) row.findViewById(R.id.bookmark_img_del); del.setVisibility(View.GONE); title.setText(b.text); int iconId = b.getIconResId(); if (iconId != -1) { img.setImageResource(iconId); img.setVisibility(View.VISIBLE); } else img.setVisibility(View.INVISIBLE); return row; } } }; </code></pre> <p>The only place where data is changing - when "refresh" method calls. It always calls from main thread. Why it still happen??? Help!</p> <p><strong>WHEN EXACTLY java.lang.IllegalStateException EXCEPTION OCCURED? ** **When I expressly run "refresh" method from non-UI thread, I get another exception (CalledFromWrongThreadException) at moment of _adapter.notifyDataSetChanged() call:</strong></p> <pre><code>10-12 13:20:29.057: ERROR/AndroidRuntime(24746): FATAL EXCEPTION: Thread-27 10-12 13:20:29.057: ERROR/AndroidRuntime(24746): android.view.ViewRoot$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views. 10-12 13:20:29.057: ERROR/AndroidRuntime(24746): at android.view.ViewRoot.checkThread(ViewRoot.java:2837) 10-12 13:20:29.057: ERROR/AndroidRuntime(24746): at android.view.ViewRoot.invalidateChild(ViewRoot.java:619) 10-12 13:20:29.057: ERROR/AndroidRuntime(24746): at android.view.ViewRoot.invalidateChildInParent(ViewRoot.java:645) 10-12 13:20:29.057: ERROR/AndroidRuntime(24746): at android.view.ViewGroup.invalidateChild(ViewGroup.java:2505) 10-12 13:20:29.057: ERROR/AndroidRuntime(24746): at android.view.View.invalidate(View.java:5192) 10-12 13:20:29.057: ERROR/AndroidRuntime(24746): at android.view.View.setFlags(View.java:4569) 10-12 13:20:29.057: ERROR/AndroidRuntime(24746): at android.view.View.setVisibility(View.java:3083) 10-12 13:20:29.057: ERROR/AndroidRuntime(24746): at com.tfd.mobile.TfdSearch.TfdSearch.showProgressVisibility(TfdSearch.java:315) 10-12 13:20:29.057: ERROR/AndroidRuntime(24746): at com.tfd.mobile.TfdSearch.TfdSearch.access$0(TfdSearch.java:313) 10-12 13:20:29.057: ERROR/AndroidRuntime(24746): at com.tfd.mobile.TfdSearch.TfdSearch$SearchList.getSuggestions(TfdSearch.java:783) 10-12 13:20:29.057: ERROR/AndroidRuntime(24746): at com.tfd.mobile.TfdSearch.TfdSearch$SearchList.refresh(TfdSearch.java:823) 10-12 13:20:29.057: ERROR/AndroidRuntime(24746): at com.tfd.mobile.TfdSearch.TfdSearch$8$1.run(TfdSearch.java:443) 10-12 13:20:29.057: ERROR/AndroidRuntime(24746): at java.lang.Thread.run(Thread.java:1096) </code></pre>

    2. COI call refresh from: 1. TextChangeListener of editText. 2. setDisplayMode method. This method call from different places around code, but a lot of UI objects touched in this method before refresh called so if it ever been called from non-UI thread it would failed more before "refresh" get chance to be called.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
