Error Handling Documentation

[benjchristensen]

Common questions are related to error handling such as retry, exponential back off, checked exceptions, user functions throwing, and handling different errors differently.

Let's add a section to the docs with code examples for these things and explaining the Rx contract with idiomatic solutions.

It should show how to convert from imperative try/catch thinking.

I've started work on this here: https://github.com/Netflix/RxJava/wiki/Error-Handling

Thank you.

I would be happy to contribute to the documentation. What's currently missing or what's partially complete that would need better support ?

[DavidMGross]

Here is what we have currently:
https://github.com/ReactiveX/RxJava/wiki/Error-Handling
It could use some fleshing-out with concrete examples.

There are also the operator pages for the onError...() operators, retry(), and such, which are now at the reactivex.io site:
https://github.com/ReactiveX/RxJava/wiki/Error-Handling-Operators

Those 2 wiki pages have both Error Handling label on a sidebar. It seems that the latter should be Error Handling Operators.

Thanks, @koral-- updated the wiki.

Closing as it will be handled via #6001
