Is it possible to have multiple Shared Preferences per app? If you create a PreferenceActivity, the values by default are persisted to /data/data/[PACKAGE_NAME]/shared_prefs/[PACKAGE_NAME]_
preferences.xml
Is there a way to have multiple such files and which one to use for a given PreferenceActivity?
Sure:
If you use
PreferenceManager.getDefaultSharedPreferences(context);it will create the file you mention.If you use
context.getSharedPreferences("OtherPrefs", Context.MODE_PRIVATE);it will create a file (and SharedPreferences object) in /data/data/[PACKAGE_NAME]/shared_prefs/OtherPrefs.xml.
