[todo‑mvp‑rxjava] What is the purpose of setLoadingIndicator() need to check getView() is null or not

I guess it can prevent the async call setLoadingIndicator() when view was destroy.
But in `todo‑mvp‑rxjava`, the async call would be dispose when view on pause.
Is it necessary to check view is null or not ?

Locate the setLoadingIndicator() implementation in the todo-mvp-rxjava sample and inspect how it uses getView(). Trace the asynchronous call's disposal during the view's pause lifecycle, then determine whether the null check is redundant and record the rationale or required change in the issue.
