    <p>I'm trying to make a world creator thing like in games and I am using shared preferences to store the arrays and such. But there is a problem. I am trying to update it from another class so I use static variables to do so. But when I go back to the original class with the list view, I find out that nothing has been updated. Any ideas? Here is the code. Oh and no errors came in the logcat.</p> <p>ListView class.</p> <pre><code>package you.don't.need-to-know; import android.app.ListActivity; import android.content.Intent; import android.content.SharedPreferences; import android.os.Bundle; import android.preference.PreferenceManager; import android.view.View; import android.widget.ArrayAdapter; import android.widget.ListView; public class WorldMenu extends ListActivity{ public static SharedPreferences prefs = null; static String splitter; String[] worldList; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); prefs = PreferenceManager.getDefaultSharedPreferences(this); splitter = "Create World," + prefs.getString("worldString", ""); worldList = splitter.split(","); setListAdapter(new ArrayAdapter&lt;String&gt;(WorldMenu.this, android.R.layout.simple_list_item_1, worldList)); } @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){ Intent openWorldNamer = new Intent("you.don't.need-to-know"); startActivity(openWorldNamer); } } } </code></pre> <p>The Updater:</p> <pre><code>package you.don't.need-to-know; import android.app.Activity; import android.content.Intent; import android.content.SharedPreferences.Editor; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.EditText; public class WorldCreator extends Activity{ EditText worldNameEditor; Button saver; static String updater; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.activity_worldcreator); worldNameEditor = (EditText) findViewById(R.id.editText1); saver = (Button) findViewById(R.id.button1); updater = worldNameEditor.getText().toString() + ","; saver.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub Editor editor = WorldMenu.prefs.edit(); editor.putString("worldString", updater); editor.commit(); Intent openListWorld = new Intent("you.don't.need.to-know"); startActivity(openListWorld); } }); } @Override protected void onPause() { // TODO Auto-generated method stub super.onPause(); } } </code></pre> <p>Edit: New Code updated with closer to fixing.

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).
