App crashes at boot, likely permission issue

[Georift]

Hey thanks for the App. It worked for a little while, but I think after setting a default photo I get a crash at boot.

I'll take a look shortly see if I can spot this issue. Just leaving this here as a reminder to myself. 👍

Thanks for leaving that crash report and for starting the issue. I'll use it as a place to keep notes for myself as well.

I've received some crash reports before and it looks like a permission issue, but I haven't been able to reproduce the crash in my Android Studio emulators or the physical devices I have. The crash report mentions that I have to obtain access using ACCESS_OPEN_DOCUMENT. I thought I did that in line 81 in MainActivity.kt, but I must have missed something somewhere.

If you could take a look I'd definitely appreciate it. I'm still clawing my way up the learning curve.

Hello, the app crashes at boot on my smartphone too (Android 12). I think it's since the v2.2.

Thanks for the crash report. I'm still trying to reproduce the issue on my devices or emulators. What device do you have?

[Georift]

Very delayed reply, I'm running Graphene OS on a Pixel 6. That's probably the cause if I were to guess. Permissions can sometimes be a little more locked down.

[JS-HobbySoft]

Thanks for the reply, I'd agree with your assessment. I've been meaning to try GrapheneOS, maybe this is a sign I need to install it.

The way I made it crash was:

1. Load background image
2. Close app
3. Delete background image from gallery
4. Try to open app again

I was not able to open the app again until I reinstalled it, which makes me think the app is trying to load a file that doesn't exist anymore.

@lufte Thanks for that crash report. You were right, the app didn't have any error checking on the background image load process. I released v3.2 to fix the issue.

To continue my notes on the permission-related crashes, I installed GrapheneOS on a Pixel 5 that I had lying around and the app loaded without crashing. I just used the defaults so there may be a setting somewhere that changes the permission handling. I'll still keep tinkering with it. It's a little strange to be disappointed when my app doesn't crash, but at this point I'd be very happy to see the permission crash on my own device or emulator where I could debug it.
