Creating a sample Todo database model

Todo.java

@DatabaseTable(tableName = "todo")
public class Todo {

    @DatabaseField(generatedId = true)
    private Long id;

    @DatabaseField
    private String title;

    @DatabaseField
    private String description;

    @DatabaseField
    private Date dateCreated;

    @DatabaseField
    private Date dueDate;

This doesn't compile in https://gist.github.com/horaceheaven/c85a9414dc787aa5c337#file-todo-java with ormlite4.48
The class needs a empty constructor and the constructor that you are using in the activity

@DatabaseTable(tableName = "todo")
public class Todo {

    @DatabaseField(generatedId = true)
    private Long id;

    @DatabaseField
    private String title;

    @DatabaseField
    private String description;

    @DatabaseField
    private Date dateCreated;

    @DatabaseField
    private Date dueDate;

    public Todo(){

    }

    public Todo(String title, String description, Date dateCreated, Date dueDate) {
        this.title = title;
        this.description = description;
        this.dateCreated = dateCreated;
        this.dueDate = dueDate;
    }
}
