How to handle error exceptions with RxJava 2?

I have UserDoesNotHaveApiKey exception with the following code:

public class UserDoesNotHaveApiKeyException extends Exception {}

Now on Splash screen, I do some check if a user has an API key or not and I want to throw UserDoesNotHaveApiException inside onError and open login screen.

enter image description here

As you can inside onError I have if statement and it always goes to else, even it is obvious that I have a correct exception.

Why?

Long story short, RuntimeException is different than other exceptions.

You could throw an Exception, an appropriate existing subclass of it (except RuntimeException and its subclasses which are unchecked), or a custom subclass of Exception.

In Java, there are two types of exceptions – checked and unchecked exception. Here’s the summary:

  • Checked – Extends java.lang.Exception, for recoverable condition, try-catch the exception explicitly, compile error.
  • Unchecked – Extends java.lang.RuntimeException, for unrecoverable condition, like programming errors, no need try-catch, runtime error.
