com.google.firebase.database.DatabaseException: Serializing Arrays is not supported, please use Lists instead

Question

I am trying to persist a custom object using the following code:

DatabaseReference databaseReference = FirebaseDatabase.getInstance().getReference();
Databas         


        

Answer 1

Add @Exclude to the functions that FB tries to interpret, like those that return a Drawable.

@Exclude
public Drawable getUnitColorImage(){
    return TextDrawable.builder().buildRound("", prefColor);
}
