I am loading a PreferenceScreen from an xml file to use as the screen to configure a new event so I'm attempting to clear and reset the values of the SharedPreference this activity is using. The problem I'm encountering is that when attempting to move to using a named preference manager, it seems the preference gets cleared but when I select an EditTextPreference element, the old data is still the default entered text on the popup. In my onCreate method I'm attempting to initialize the preferences, clear them, then set to default values. My understanding from the dev resources were that there's no way to clear/reset in one step.. <pre><code>private static final String PREFNAME = "newmeetingactivity.preferences"; //load preferences and set name addPreferencesFromResource(R.layout.newmeeting_preferences); getPreferenceManager().setSharedPreferencesName(PREFNAME); getPreferenceManager().setSharedPreferencesMode(MODE_PRIVATE); //Clear the preferences _sharedPreferences = getPreferenceManager().getSharedPreferences(); SharedPreferences.Editor ed = _sharedPreferences.edit(); ed.clear(); ed.commit(); //Load default preferences from file again PreferenceManager.setDefaultValues(this, _sharedPreferences.toString() , MODE_PRIVATE, R.layout.newmeeting_preferences, true); </code></pre> Edit: To try to better explain what I'm attempting to do (in case my approach is way off): I need to clear shared preferences used on a given activity while not interfering with the settings from other activities (as they should persist indefinitely).

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.
