Using ArrayList with sharedpreferences.

Question

Am trying to store the values in my ArrayList with SharedPreferences and access them in another class.This is what i have tried so far.

public class sample {

final static String file = "myFile";
SharedPreferences fileName;

protected void onCreate(Bundle savedInstanceState) {

            Sharedpreferences.Editor list = SharedPreferences.edit();
            list.putStringArray("key", 0);
            list.commit();

    }
}

public class sample2 {

String array[] = {"can", "you", "help", "me", "with", "this?"};

protected void onCreate(Bundle savedInstanceState) {

         Random random = new Random();
         int x;
         x = random.nextInt(5);

         String generatedValue = arr[x];

         String get = fileName.getString("key", 0);
         SharedPreference.Editor editList = SharedPreferences.edit();
         editList.putString("key", get);
         editList.commit();
         }
}

Any help would be appreciated.

i want to store the values of my string array to the arraylist from the other class using sharedpreferences — terch, Feb 16 '14 at 17:04
Activities under the same Application package can read the same SharedPreferences file. — DeeV, Feb 16 '14 at 17:09
my problem is, I want to store those values in the arraylist permanently, and generate another values not equal to the existing values of the arraylist and store — terch, Feb 16 '14 at 17:11
