Hello, I want to have some preferences stored forever by my application, for example username, remember me, etc...and other preferences to be stored only until the application is closed, or the user logs out. So basically my question is how do I delcare which preferences must be stored for ever,

Re: [android-developers] SharedPreferences

The stuff that should be cleared when the application is closed by the OS are not preferences, so do not implement them as such. Use static data members or something along those lines, so they will go away automatically when Android terminates the process. On Tue, Mar 6, 2012 at 10:00 AM,

[android-developers] SharedPreferences not persisting

I've been trying to save some state variables in the SharedPrefs, this seems to work fine when onPause, and onStop are called but not when OnDestroy() is called. When that happens the next time my activity loads the preference values have disappeared. Here is the code I use to save the variables:

Re: [android-developers] SharedPreferences not persisting
