SharedPreferences.onSharedPreferenceChangeListener not being called consistently

Question

I\'m registering a preference change listener like this (in the onCreate() of my main activity):

SharedPreferences prefs = PreferenceManager.get         


        

Answer 1

this accepted answer is ok, as for me it is creating new instance each time the activity resumes

so how about keeping the reference to the listener within the activity

OnSharedPreferenceChangeListener listener = new OnSharedPreferenceChangeListener(){
      public void onSharedPreferenceChanged(SharedPreferences prefs, String key) {
         // your stuff
      }
};

and in your onResume and onPause

@Override     
public void onResume() {
    super.onResume();          
    getPreferenceScreen().getSharedPreferences().registerOnSharedPreferenceChangeListener(listener);     
}

@Override     
public void onPause() {         
    super.onPause();          
    getPreferenceScreen().getSharedPreferences().unregisterOnSharedPreferenceChangeListener(listener);

}

this will very similar to what you are doing except we are maintaining a hard reference.
