Getting Nullpointer exception when i try to insert data in sqlite

In my database there are 2 tables. One for login info and another for store some report data. When i try to insert data in login table, it is successful. But when i try to insert report data, i get "NullPointerException" error. In different ways i checked and confirm that i am not sending any null value.

Please check the code below.

public class StoreReport {

public static final String KEY_ROWID = "_uid";
public static final String KEY_NAME = "username";
public static final String KEY_password = "userpassword";

private static final String DATABASE_NAME = "personal.db";
