I am using 8 EditText boxes from the NewCard.xml from which i am taking the values and when the save button is pressed i am storing the values into a database, in the same process of saving i am trying to get the values and present them into 8 different TextView boxes on the main.xml file and when i press the button i get an FC from the emulator and the resulting error is java.lang.NullPointerException. If Some 1 could help me that would be great, since i have never used databases and this is my first application for android and this is the only thing keepeng me to complete the whole thing and publish it on the market like a free app. Here's the full code from NewCard.java.

public class NewCard extends Activity 
{
    private static String[] FROM = { _ID, FIRST_NAME, LAST_NAME, POSITION, POSTAL_ADDRESS, PHONE_NUMBER, FAX_NUMBER, MAIL_ADDRESS, WEB_ADDRESS};
    private static String ORDER_BY = FIRST_NAME;

    private CardsData cards;

    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.newcard);

        cards = new CardsData(this);

        //Define the Cancel Button in NewCard Activity
        New_Cancel = (Button) this.findViewById(R.id.new_cancel_button);
            //Define the Cancel Button Activity/s

                    }
                }
