Robert, Do you start the emulator with "Wipe data" option, by any chance?
If you are, that explains it, as wiping the data means.... well, wiping the data.
The preferences are stored in the file system of the emulated Android device, just like on a real phone, not directly within the host computer's file system.
You can find the files under: /data/data/<your package name>/shared_prefs -- Kostya 23.04.2011 10:02, Zsolt Vasvari пишет:
No idea about the MODE_PRIVATE stuff, but I use PreferenceManager.getDefaultSharedPreferences() and it works fiine. Why do you need to control the file name?

String s2 = getStringFromStorage(keyName); Where SHARED_PREFS_FILENAME is a private final static string and keyName is the name of whatever key I'm currently using as a field name. The commit works fine, I don't get an exception. As you can see I added a test that retrieves the recently committed string and when I check it (s2) the value is fine. So I am not having any problems with shared preferences storage during the lifetime of my app. However, when I relaunch the application in the emulator the shared preferences storage area is empty and I can't find the values I stored in the last emulator session. I did some reading and as far as I can see the stored values should persist across sessions, apparently they are saved in an XML file belonging to the emulator. Yet I am having problems. Can anyone tell me why my shared preferences storage values are not persisting between Android emulator sessions? -- roshcler
