[qingfengmy]

i add prepopulated database ,like this:

<meta-data
            android:name="AA_DB_NAME"
            android:value="populate.db" />
<meta-data
            android:name="AA_DB_VERSION"
            android:value="1" />

i put populate.db at assets folder.

i have other classes like this:

@Table(name = "users", id = "_id")
public class User extends Model implements Serializable{
}

when i run my program，the users table did't be created. but when i delete the populate.db at assets folder.the users talbe is be created normaly after my program runs.
