Answer 1

Instead of using CompositeDisposable.dispose(), you can better use CompositeDisposable.clear() so you don't have to create a new CompositeDisposable: method documentation.

clear() //Atomically clears the container, then disposes all the previously contained Disposables.

dispose() //Dispose the resource, the operation should be idempotent.
