onDataChange called receiving warning

[hermanghub]

I've tried the readValue method and managed to retrieved the records on Firebase realtime database. Then I try to implement onDataChange with (MyClass.class, new DataChangeListener()) and override the onChange method.

When running my app, I saw below in Logcat: W/ClassMapper: No setter/field for xxxx found on class ...MyClass

and onChange is not called.

Please find the definition of MyClass as below: public class MyClass { public String initials; public String dateTime; public String remarks;

public MyClass() {}
public MyClass(String initials, String dateTime, String remarks) {
    this.initials = initials;
    this.dateTime = dateTime;
    this.remarks = remarks;
}

public String getInitials() {
    return initials;
}

public void setInitials(String initials) {
    this.initials = initials;
}

public String getDateTime() {
    return dateTime;
}

public void setDateTime(String dateTime) {
    this.dateTime = dateTime;
}

public String getRemarks() {
    return remarks;
}

public void setRemarks(String remarks) {
    this.remarks = remarks;
}

}

What have I done wrong or missing?

Also, what I really want to do is to maintain some sort of hall of fame records in Firebase database and display. How should I code to retrieve the 10 latest records from the database? or I need to wait for the next release for filtering/query feature?

Thanks in advance. Herman

Hi!

Unfortunately at this point is no way to get limited number of rows. You can try limit records by structure. Yes, support for filtering/querying will be here in next release - but at this moment i don't know when it will be - I hope at some point of February .

Can you put some sample code, how do you call GdxFireapp API?

Please refer to the sample code I mentioned in #4. Thanks.

W/ClassMapper: No setter/field for xxxx found on class ... is throwing when there are some fields inside DB which your POJO does not cover by setters. Look here: https://firebase.google.com/support/guides/firebase-android#update_your_java_model_objects . GdxFireapp Api ignore unknown fields on ios, but i still working on it at android platform. I'll let you know here when I'm done - very soon

Thanks for the reference link. I'll study it. Thanks.

Recently used v1.3.1. The warning is gone on both Android and ios! Thanks anyway!
