How to migrate from getMessagesByTimestamp to getPreviousMessagesByTimestamp on android

currently i have this implementation to fetch messages

```auto
channel?.getPreviousMessagesByTimestamp(
                    createdAt ?: Long.MAX_VALUE,
                    false,
                    CHANNEL_MESSAGE_LIMIT,
                    true,
                    BaseChannel.MessageTypeFilter.ALL,
                    null,
                    null,
                    true,
                    messageHandler
            )

```

i tried migrating to the newer api, it was a bit confusing but i ended up with this,

```auto

val params = MessageListParams(
                CHANNEL_MESSAGE_LIMIT,
                CHANNEL_MESSAGE_LIMIT,
                BaseChannel.MessageTypeFilter.ALL,
                allowedMessageTypes,
                userIds,
                false,
                true,
                true,
                true,
                true,
                true,
                true
            )

            channel?.getMessagesByTimestamp(
                createdAt ?: Long.MAX_VALUE,
                params,
                messageHandler
            )

```

but this implementation didn’t work, the pagination just returns the same set of messages and completely broke the current implementation.

Hello @arjun,

Apologize for the delay in our response. I had a change to speak with one of our Android engineers and it sounds like you should be passing `0` to `nextResultSize` instead of `CHANNEL_MESSAGE_LIMIT`. This is likely what is causing you to receive the duplicate data.
