Unexpected NullPointerException When Accessing Fragment Arguments in Activity on Android 14
I'm stuck on something that should probably be simple. I'm sure I'm missing something obvious here, but I'm working with a `NullPointerException` when trying to access arguments passed to a Fragment from an Activity. My setup involves using `Fragment` arguments to pass data between my `MainActivity` and `MyFragment`. The code looks like this: In my `MainActivity`, I initialize the fragment and pass the arguments: ```kotlin val myFragment = MyFragment().apply { arguments = Bundle().apply { putString("key", "value") } } ``` Then I add the fragment to the activity: ```kotlin supportFragmentManager.beginTransaction() .replace(R.id.fragment_container, myFragment) .commit() ``` In `MyFragment`, I try to retrieve the argument in `onCreateView`: ```kotlin override fun onCreateView( inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle? ): View? { val value = arguments?.getString("key") ?: throw NullPointerException("Argument 'key' is null") // rest of the code } ``` However, I'm getting the following behavior in the logcat: ``` java.lang.NullPointerException: Argument 'key' is null ``` I verified that the argument is set in `MainActivity`, and I'm running this on Android 14 with Kotlin 1.8. I'm confused as to why the `arguments` are null when the Fragment is created. Is there something I'm missing in the Fragment lifecycle or how I'm passing the arguments? I've tried moving the retrieval logic to `onViewCreated`, but the scenario continues. Any help would be appreciated! I'm working on a CLI tool that needs to handle this. Is there a better approach? This is part of a larger web app I'm building. What's the best practice here?
