Ambiguous getter for Field… Room persistence library

Question

I have the following Entity

public class User {
    @PrimaryKey
    private final long id;

    private String _id;
    private String userName;
    private          


        

Answer 1

As per documentation you need to declare getter for every field.

I can see that you have not declared your class with @Entity annotation. Also make sure you are using latest version of library as it is still in development you need to expat some ground breaking changes.

See below example it is working fine for me with below api version of Room.

api 'android.arch.persistence.room:runtime:1.0.0-alpha8'

Or you can use "alpha9" as well. Hope this will solve your problem.

@Entity (tableName = "user")
public class User {

@PrimaryKey
private int id;

private String _id;

@ColumnInfo(name = "user_name")
private String userName;

@NonNull
private String passwrod;

public User(String userName, @NonNull String passwrod) {
    this.userName = userName;
    this.passwrod = passwrod;
}

@Ignore
public User() {
}

public int getId() {
    return id;
}

public void setId(int id) {
    this.id = id;
}

public String getUserName() {
    return userName;
}

public void setUserName(String userName) {
    this.userName = userName;
}

public String getPasswrod() {
    return passwrod;
}

public void setPasswrod(String passwrod) {
    this.passwrod = passwrod;
}

public String get_id() {
    return _id;
}

public void set_id(String _id) {
    this._id = _id;
}

}
