Question

Is it possible to get the \"key\" value from a SharedPreferences file if I know the \"value\" value it is paired with?

Let\'s say I\'ve gone into the SharedPreferenc

You can try:

SharedPreferences prefs = context.getSharedPreferences(context.getPackageName(), 0);

Iterator iter = prefs.getAll().entrySet().iterator();
    while (iter.hasNext()) {
        Map.Entry pair = (Map.Entry)iter.next();
       // Check the value here
    }

You can iterate over that map and look for the value you want.
