    <p>Im trying to make a world creator in a list view that saves the world's name. But the shaed preferences causes the program to crash before the activity opens. Why is this happening? It is perfectly fine without the shared preferences. Any ideas? (that on list view click is unfinished, don't worry about that.) The errors that were most notable were the null pointerexception at the array adapter, storage == null, and skipped frames</p> <pre><code>package xxx.xxx.xxx; import android.app.ListActivity; import android.content.Intent; import android.content.SharedPreferences; import android.content.SharedPreferences.Editor; import android.graphics.drawable.Drawable; import android.os.Bundle; import android.view.View; import android.widget.ArrayAdapter; import android.widget.ListView; import android.widget.PopupWindow; public class WorldMenu extends ListActivity{ SharedPreferences prefs; String splitter; String[] worldList; PopupWindow worldNamer; Drawable background; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setListAdapter(new ArrayAdapter&lt;String&gt;(WorldMenu.this, android.R.layout.simple_list_item_1, worldList)); prefs = getSharedPreferences("worldString", 0); splitter = "Create World\\\\\\\\\\\\\\\\\\\\\\\\\\" + prefs.getString("worldString", "No worlds found."); worldList = splitter.split("\\\\\\\\\\\\\\\\\\\\\\\\\\"); } @Override protected void onListItemClick(ListView l, View v, int position, long id) { // TODO Auto-generated method stub super.onListItemClick(l, v, position, id); if(position == 0){ worldNamer = new PopupWindow(this); worldNamer.setBackgroundDrawable(null); } } } </code></pre>

    1. COWell what does the stack trace say, *exactly*? Your "errors that were most notable" sentence is particularly unclear...

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.
