Something really simple like initial settings of the application which stored in one module but read from other module(s). For example number of last active tab, some selected index from spinner etc. Thanks On Fri, Jan 9, 2009 at 9:30 PM, Mark Murphy mmur...@commonsware.com wrote: EvgenyV wrote: Hi!

If they are things that do not need to be persisted, and your application is all in one process (the default), you could just use static methods to access shared values. -- Mark Murphy (a Commons Guy) http://commonsware.com _The Busy Coder's Guide to Android Development_ Version 2.0 Published! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

SharedPreferences is private data per activity. I tried to store persist data from activity A but can't read it from activity B. Missed I something?

You just want the version of getSharedPreferences() that takes a String. On Fri, Jan 9, 2009 at 12:57 PM, Evgeny V evgen...@gmail.com wrote: Ok! I go my mistake.
