Answer 1

declare these two variable in your activity

android.content.SharedPreferences someData;
public static String filename = "mySharedString";

initialize the Shared Preferences like this:

someData = getSharedPreferences(filename, 0);

you can add elements to the Shared Preferences like this:

android.content.SharedPreferences.Editor editor = someData.edit();
            editor.putString("sharedString", stringData);
            editor.commit();

you can retrieve data like this:

String dataReturned = someData.getString("sharedString","Couldn't load data");

The Couldn't load data will be set to the dataReturned variable if the sharedString is not existed in the Shared Preferences
