MainActivity's OnCreate throws System.IO.FileNotFoundException #7195

Closed jayveedee closed 2 years ago

jayveedee commented 2 years ago

Description

I have no idea how this happens. I have a phone called Motorolla Edge 20, Android 12. Whenever I open the app I've created, OnCreate throws System.IO.FileNotFoundException (and swallows, so the app does not crash). This this did not happen before I either updated to Android 12 on my phone or in earlier versions of MAUI. One of the two, because I updated both some time ago and since it hasn't been working.

But with that said, this is only on my phone. The emulator works just fine, be it Android 11 or Android 12 (Pixel 5). So I'm not 100% sure if this has something to do with my phone. This also does not happen on a fresh MAUI install. Also something else, not sure if related but I use the WebAuthenticator from Essentials and when I try to login, the browser goes to the right site and I login, afterwards it tries to go back to the app but somehow opens another browser or something, it's very odd. This also works on the emulator but not on my phone.

Steps to Reproduce

  1. Start the project with my phone
  2. MainActivity's OnCreate throws exceptions

It would be very helpful if you could somehow pinpoint further where this is coming from and put the relevant bits in a reproduction project. It seems you already have a hunch about the Essentials authenticator which might make sense as it seems to fail on trying to read/save some encrypted key.
