my foreign key isnt working?

I am having an issue with my tables, the first table creates a reference to the data in the second table, the CARD_ID increments fine, but the foreign key in CARD_INFO_TABLE isnt autoincrementing or even realising it is a foreign key of an autoincrement, So i would just like to know, where am I going wrong!?

    public static final String CREATE_CARD_TABLE = "CREATE TABLE "
        + CARD_TABLE + "(" + CARD_ID
        + " INTEGER PRIMARY KEY AUTOINCREMENT, " + CARD_NAME
        + " TEXT )";

    public static final String CREATE_CARDINFO_TABLE = "CREATE TABLE "
        + CARD_INFO_TABLE + "(" + CARD_ID2
        + " INTEGER, " + CARD_NAME2
        + " TEXT, " + CARD_WEIGHT
        + " REAL, " + CARD_REPS
        + " INTEGER, "
        + " FOREIGN KEY " + "("+ CARD_ID2 +")"+ " REFERENCES " + CARD_TABLE + "("+CARD_ID+"));";

and then I insert data to them as follows, where am I going wrong??

public void insertEntry(String name, double weight, int reps) {
    if(flag == 0) {
        open();
        database.beginTransaction();
        ContentValues newValues = new ContentValues();
        // Assign values for each row.
        newValues.put(DataBaseHelper.CARD_NAME, name);

        // Insert the row into your table
        database.insert(DataBaseHelper.CARD_TABLE, null, newValues);
        flag = 1;
        database.setTransactionSuccessful();
        database.endTransaction();
        close();
    }
    open();
    database.beginTransaction();
    ContentValues newValues2 = new ContentValues();
    // Assign values for each row.
    newValues2.put(DataBaseHelper.CARD_NAME2, name);
    newValues2.put(DataBaseHelper.CARD_WEIGHT, weight);
    newValues2.put(DataBaseHelper.CARD_REPS, reps);

    // Insert the row into your table
    database.insert(DataBaseHelper.CARD_INFO_TABLE, null, newValues2);
    database.setTransactionSuccessful();
    database.endTransaction();
    close();
}
