Everything in my code was fine a few days ago till this error started to happened on every conversion I do on the different classes I have. (APi version 24) This is the error stack trace:

You are trying to serialize a type that has a field whose type is java.lang.reflect.Method. This either needs marked transient or you need to write a custom type adapter for it.

Can you explain a little bit more? It may be because I have a list inside my object?

No. One of your objects or or one of the types it extends from has a field
whose type is Method.

I'm having this same issue only on Samsung Galazy 8 and up and some Huawei. It runs on most other android phones. Any reason for the inconsistancy on devices?

I'm having the same issue on the Samsung device. Could anyone help me with this?

You need to use transient on the properties you don't want to serialize in your object.
