Is it safe to call `requireContext()`/`requireActivity()` in a `LiveData` observer?

As long as the observer is scoped with the view, I don’t think there is any problem

How do I know if it scoped with the view?

Whenever you call ```myLiveData.observe(this, Observer { ... })``` where `this` is your `Activity` or `Fragment`, you're ensured that the `Observer` is tied to the lifecycle of that Activity/Fragment, i.e. it will unregister itself in `onDestroy()`.

Otherwise, it will be unsafe to reference a `Context` in that `Observer` if you register it with ```myLivedata.observeForever(observer)```, unless you unregister that observer with `removeObserver(observer)` (but if you do that in a Fragment, why wouldn't you use `observe` instead ?)
