1. Fwd: OnSharedPreferenceChangeListener never receives callback


I'm not sure I understand what you are trying to do ...but if it helps any,
I ended up using a broadcast/receiver to relay the preference change. While
I could have just re-read from preferences onResume on the second activity,
I didn't want the user to see data shifting around in the list as the new
sort was applied.

Hello Connick,

sorry to bother you, but have you done, that it works now
for you ?

My situation :
   Service  A has SharedPreference .. write them after some kernel

  Activity B can read them ( i.e. in onResume )

  BUT, if the Activity is currently shown   I will update them via
 a SharedPreferenceChangeListener. But he isn't called , when Service
a changes the Preference.

 For me a very simular situation to yours, right ?

So what is the missing point ? Thanks a lot !
