[android-developers] Re: Sharing SharedPreferences from two different processes
Michael, Sorry but I don't understand your example. You are specifying MODE_PRIVATE which is what I am doing... SharedPreferences myMemory = getSharedPreferences(myMemory, MODE_PRIVATE); Are you saying that if I specify | 0x4 (don't know what that means) that it will be the same as specifying MODE_MULTI_PROCESS? btw, I'm targeting 2.33 gingerbread.

The additional flag does no harm in pre-level-11 runtimes. Also notice that OnSharedPreferenceChangeListener will not trigger across processes.

Yes, appending | 0x4 will result in the same value.

Re: [android-developers] Re: Sharing SharedPreferences from two different processes
No, it works just fine on all API levels. You can write in one process and read in another one. The only thing that is not working across processes is change notifications.
