Project mention: Nextcloud cries foul over Google Play Store app rejection | news.ycombinator.com | 2025-05-13
> I believe the nextcloud team when they say they need the permission.
I don't (and I do use NC). The sentence "SAF cannot be used, as it is for sharing/exposing our files to other apps" is simply wrong and llm_thread is right that SAF should be able to handle that use case,see
https://developer.android.com/training/data-storage/shared/d...
There are some restrictions regarding which directories you can access, but for most use-cases it should be perfectly fine. It's also not that this should come as a surprise to them. In fact, there's an issue about this from the NC team themselves from August '23:
https://github.com/nextcloud/android/issues/10123
Why they still think SAF cannot be used is a mystery to me.
