Re: [android-developers] Widget-specific Preferences

Jake,

It's possible to make your subclass of PreferenceActivity use a specific
preference file by putting something like this inside its onCreate:

PreferenceManager prefManager = getPreferenceManager();
prefManager.setSharedPreferencesName("widget_pref_" +
String.valueOf(widgetId));

This seems somewhat inefficient though, because each widget will get its
own preference storage file.

To use a single preference file where each widget gets its own set of
keys (dependent on a particular widget id), you could try using
Preference.setKey:

for preference : all Preferences in the screen {
String keyOriginal = preference.getKey();
String keyWithWidgetId = keyOriginal + String.valueOf(widgetId);
preference.setKey(keyWithWidgetId);
}

Hope this helps.
