Android SQLite没有这样的表/预填充数据库

基于本文，我在应用程序中预装了一个sqlite数据库： [链接]

因此，将成功创建/复制/打开数据库（DDMS、文件浏览器等）。在下一步中，我想在表中插入一些数据。然后我得到了“没有这样的表格”的错误，我不明白为什么

创建/打开数据库

public void createSQLite() {
    try {
        helper.createDataBase();
        helper.openDataBase();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

    public static final String cust_id = "customer_id_fk";
public static final String app_cust_id = "app_cust_id_pk";
public static final String hash = "app_hashvalue";
public static final String version = "app_version";
public static final String date = "activation_date";
public static final String handy = "handynr";
public static final String device = "devicename";
public static final String active = "activated";
public static final String APP_CUSTOMER = "app_customer";

表格的名称和属性

public void createSQLite() {
    try {
        helper.createDataBase();
        helper.openDataBase();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

    public static final String cust_id = "customer_id_fk";
public static final String app_cust_id = "app_cust_id_pk";
public static final String hash = "app_hashvalue";
public static final String version = "app_version";
public static final String date = "activation_date";
public static final String handy = "handynr";
public static final String device = "devicename";
public static final String active = "activated";
public static final String APP_CUSTOMER = "app_customer";

插入选项卡中

public void addAppCustomer(Activation act) {        

    long rowId = -1;
    SQLiteDatabase db = sqlite.getWritableDatabase();
    ContentValues val = new ContentValues();

    // Create values
    val.put(app_cust_id, act.getApp_customer_id());
    val.put(cust_id, act.getCustomer_id());
    val.put(hash, act.getImei());
    val.put(version, act.getAppversion());
    val.put(date, act.getActivationDate());
    val.put(handy, act.getPhone_number());
    val.put(device, act.getDevice_name());
    val.put(active, act.getActivated());
    rowId = db.insert(APP_CUSTOMER, null, val);
}

再次：创建数据库/表。当尝试插入上述数据时，我得到“无此类表格”错误（app\U客户）

提前谢谢

编辑：

创建表语句

    CREATE TABLE `app_customer` (
      `id` INTEGER PRIMARY KEY AUTOINCREMENT,
      `app_cust_id_pk` INTEGER NOT NULL,
      `customer_id_fk` INTEGER NOT NULL,
      `app_hashvalue` VARCHAR(128) NOT NULL,
      `app_version` VARCHAR(45) NOT NULL,
      `activation_date` NUMERIC NOT NULL,
      `handynr` VARCHAR(16) NOT NULL,
      `devicename` VARCHAR(45) NOT NULL,
      `activated` INTEGER NOT NULL DEFAULT '0'
    )

你能发布创建表语句吗？请考虑使用比五岁的博客文章更现代的东西，这样。我已经更新了我的问题（见创建表）。
