Cannot get real path of some images on Android API 33 I have a strange situation and not sure how to debug further. I need to get the real path of a selected image from the gallery so I can upload it to a server via an API. It works perfectly that I can tell on a virtual Pixel 6 API 25, but fails on my real device, a Samsung Galaxy S20 with API 33. But it only fails on some photos.

Which is the best approach for an app with multiple users using Room database? I'm developing an app (Android, Kotlin) that allows the user to register different documents with specific information in Room database. I'll implement in the app to only be able to display the files registered if the user is logged in. It concerns me because if a device is shared, everything you need is to log in to access another user data, which is totally not cool. I'm using room database and firebase for authentication. I was wondering if every time the user add a new file to room...

lifecycleScope doesn't get cancelled when app on background Docs say that A LifecycleScope is defined for each Lifecycle object. Any coroutine launched in this scope is canceled when the Lifecycle is destroyed. But then they say that you should use repeatOnLifecycle function to automatically cancel the job when app on background. (Or also we can assign result to job variable, and cancel it manually on destroy) Shouldn't it cancel the coroutine itself when app on destroy called, because it says its scope is coupled with lifecycle?
