Are you trying to let the user change the value with a preference activity,
and still get access to the value from code?
If so, make sure that the shared prefs storage is the same in both cases:
Option 1:
- In your code snippet, call
PreferenceManager.getDefaultSharedPreferences() rather than
getSharedPreferences("settings"), to get the same shared prefs storage as
used by the preference activity.
Option 2, opposite of option 1:
- In your PreferenceActivity subclass, call
getPreferenceManager().setSharedPreferencesName("settings") telling the
prefs activity to use the same shared prefs storage as used in your snippet.
