How to save Bitmap to a file asynchronously?

I want to save Bitmap to a file. Do it using FileOutputStream. On StackOverflow write that such operations should be done asynchronously. I want to know is it possible to achieve this using RxJava? If Yes then I can show how )) !

Yes, it is better to do in the background. Something like this:
D Disposable = Observable.fromCallable(() -> {
 // save bitmap

And don't forget to call d.dispose() method in onDestroy() of your activity or fragment.
PS code is not tested, I am writing from memory from the phone.
