I can not delete part of [result.data], I am in trouble

[chocowa198]

Hello.

Let me questions.
In the table below, 1 and 2 will fail.

It crashes at run time.
message
"Unsupported OperationException"

No error will occur.
However, as you update the timeline, it will not be deleted.

If I get advice on these, I am very happy.

    call.enqueue(new Callback<List<Tweet>>() {
        @Override
        public void success(Result<List<Tweet>> result) {
            
            result.data.remove(index); //  error 1
            
            tweetList.addAll(result.data);

            tweetList.remove(Index); // error 2

            adapter.notifyDataSetChanged();
