I'm creating a reusable fragment in my project.

I want to force the calling Fragment to send the reference through a Bundle so I can get it with getArguments().

How to throw an Exception that I don't want to handle, so I'll force the implementation?

This is how I planed to do it:

Bundle bundle = getArguments();
    String callerFragment = bundle.getString(COMMON_COMPONENT_CALLER_TAG);
    if(callerFragment == null){
        throw new UnknownCallerException("Missing caller name");
    }

Just throw a RuntimeException... What's the problem with this code? – OneCricketeer Sep 28 '17 at 13:39
Using RuntimeException solves the problem. Android Studio forces to handle the custom Exception. – kike Sep 28 '17 at 13:42
You can extend RuntimeException, if you wish – OneCricketeer Sep 28 '17 at 13:46
