On Android, cannot save an object with a BigDecimal field

[eli...@innovorder.fr]

Hi,

On android I try to save an object to the firebase real-time database, it used to work on version 2.5.2 but on firebase version 9.8.0 I have the following exception when I try to save : 

com.google.firebase.database.DatabaseException: Failed to parse node with class class java.math.BigDecimal

                                                                                                        at com.google.android.gms.internal.zzamm.zza(Unknown Source)

                                                                                                        at com.google.android.gms.internal.zzamm.zzbt(Unknown Source)

                                                                                                        at com.google.android.gms.internal.zzamm.zza(Unknown Source)

                                                                                                        at com.google.firebase.database.DatabaseReference.zza(Unknown Source)

                                                                                                        at com.google.firebase.database.DatabaseReference.setValue(Unknown Source)

Any suggestion on how to handle this on the new version of firebase ?

Best regards.

Hello (Elid?),

Can you please share some code and sample data demonstrating the issue? Are you, perhaps, ignoring the offending field in your old 2.x code by using Jackson annotations?

Hi Kato, 

Here an example :

A simple java object :

public class Pojo {

    private BigDecimal value;

    public Pojo(BigDecimal value) {
        this.value = value;
    }

    public BigDecimal getValue() {
        return value;
    }

    public void setValue(BigDecimal value) {
        this.value = value;
    }
}

Then I try to push this object on the firebase database with

Pojo pojo = new Pojo(new BigDecimal(5));
String key = databaseReference.push().getKey();
databaseReference.child(key).setValue(pojo);

Then I get the following exception 

com.google.firebase.database.DatabaseException: Failed to parse node with class class java.math.BigDecimal

at com.google.android.gms.internal.zzamm.zza(Unknown Source)

at com.google.android.gms.internal.zzamm.zzbt(Unknown Source)

at com.google.android.gms.internal.zzamm.zza(Unknown Source)

Tell me if you need something else.

Thank you

Elid.

Make a converter in Java between String and BigDecimal,

Store the String value in Firebase Database, restore as String but parse to BigDecimal Constructor in your class java.
