Kostya, I like your second suggestion.
So in my Preference Activity's onCreate() I should get every preference by original key name and then reset the key name to include the widget. That means I'll have a full set of non-unique preference keys without any data but that should not really be an issue. According to the docs it does not look like there is a method to iterate through "all preferences" so, instead, I'll have to get every preference by specific key name and manually change each one. Have I missed a more direct way of changing all the keys? If I use an onClickListener() and on SharedPreferenceChangeListener() to detect specific preference clicks or changes to a preference, I can parse out the widget ID from the key so that I know which specific widget has been effected. I can then make sure that I update just that specific widget accordingly. Can you think of a better way to do that? To facilitate parsing out the widget id, I have already externalized all my key names as string resources so that I can edit the string to include a ":". This way I can parse out the text that follows the ":" and get the widget id. Did you do something similar or did you not have the need to know which widgetid has had its preference changed? ...Jake >>>>> "KV" == Kostya Vasilyev <[email protected]> writes: KV> Jake, KV> It's possible to make your subclass of PreferenceActivity use a KV> specific preference file by putting something like this inside KV> its onCreate: KV> PreferenceManager prefManager = getPreferenceManager(); KV> prefManager.setSharedPreferencesName("widget_pref_" + KV> String.valueOf(widgetId)); KV> This seems somewhat inefficient though, because each widget will KV> get its own preference storage file.
