您的查询不正确：

  • 您缺少表名
  • 您在键和自动增量之间缺少空格

所以纠正它如下：

String DATABASE_CREATE = "create table TableName(id integer primary key autoincrement, "
+ "name VARCHAR not null, dob date, contact VARCHAR, email VARCHAR)";

现在它将起作用。

请在此处尝试使用表名

private static final String DATABASE_CREATE
 = "create table TABLENAME (id integer primary key autoincrement, "
 + "name VARCHAR not null, dob date, contact VARCHAR, email VARCHAR);";

这似乎是背后的原因

没有这样的表：profiles
