buddy Are you a developer? Can you interpret what the crash log mean?
I'm not a GrapheneOS dev. I'm just a random person helping out when I can.
I can understand the crash log, but the issue is I don't know anything about this CHOOSER intent, except the obvious: that it's supposed to open an activity that chooses something.
buddy Yes I remember trying to disable some system apps since Android 12.
This is probably the cause. I agree with de0u that to fix this you can go through system apps and enable any that were disabled.
buddy So could it be some code changes on AOSP 14 when handling intent to share texts or files?
Yes. That's probably what broke your share functionality when upgrading to Android 14. Maybe some functionality was moved to another system app. So, while you're still doing the same exact thing, the system could be doing it differently.
buddy Or my OTA update is corrupted? I really hope not.
Again, I agree with de0u. If the update was messed up somehow, it wouldn't have installed.
