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

In case this helps others that are receiving the same error, I was getting the same error and the solution ended up being the following for me:

Changing:

databaseReference.child("somechild").setValue(etName.getText());

To:

databaseReference.child("somechild").setValue(etName.getText().toString());

As @fraggjkee points out, Firebase attempts to serialize getters, and this was the similar issue here with firebase attempting to serialize the result of the .getText().

Hope this helps others!
