Is `Activity Results API` stable for production use?

Yes, it's released as part of stable release of Androidx, so it's stable now
Also onActivityResult is officially deprecated and new result api is recommended approach

onActivityResult is not deprecated, it's simply lower level API than the androidx.activity result API in jetpack

It's deprecated in Androidx ComponentActivity
<https://developer.android.com/reference/androidx/activity/ComponentActivity#onActivityResult(int,%20int,%20android.content.Intent)|https://developer.android.com/reference/androidx/activity/ComponentActivity#onActivityResult(int,%20int,%20android.content.Intent)>

it's very much not in `Activity` - `ComponentActivity` is trying to nudge you to use the newer API since it's easy to break the operation of the activity result APIs if you don't call super :slightly_smiling_face: <https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:activity/activity/src/main/java/androidx/activity/ComponentActivity.java;l=624?q=ComponentActivity.java|https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:activity[…]ctivity/ComponentActivity.java;l=624?q=ComponentActivity.java>

oh wow I saw the deprecation in ComponentActivity and just assumed it was deprecated everywhere - confusing if you ask me.

one gotcha with `ActivityResultContract` is that it is written in java so the generics do not support nullability - i.e. it’s easy to accidentally define the output type as non-null and then implement `parseResult` as nullable :cry:

Well, of course, but you cannot use Result API with android.Activity out of the box, isn't it? Of course it cannot be deprecated on Android framework level, there is no replacement tnere

But deprecation on ComponentActiviti affecta pretty much everyone. I think it's pretty rare for modern apps to not use Androidx activity
