Crash on unlock after Android restart - JonathanKChang

[Eridyne]

Each reboot triggers one single crash dialog for Chrono, immediately after first unlock. It doesn't seem to impede Chrono functioning afterwards.

Suggestion for JonathanKChang - If you intend to keep your fork open, you may want to consider opening issues on it - there's no real indication that the dev(s) intend to return here, at this point.

[JonathanKChang]

Do you have any info on the crash or perhaps a logcat?

I opened up my issues for now or feel free to @ tag me, but the devs have said they intend to return, so here's hoping.

Sorry, it took a minute to get back to this, but this might help. @JonathanKChang

I did get a filtered logcat, and the ROM offered a crash log, so that's here as well.

I mentioned what appears to be the same problem in another issue, rather than creating a new one 😅: #495 (comment)

The log I got shows essentially the same thing as above: https://bin.kv2.dev/~69f4fa0e5c159600136abc8d

As I am rooted, I just disabled one of the receivers (com.flux.flutter_boot_receiver.BootBroadcastReceiver) which stopped the error, and the app is still working fine without it.

Nice, thank you for testing with that disabled. Here's an updated release

Oh, and I 'fixed' this by disabling com.flux.flutter_boot_receiver.BootBroadcastReceiver (there are several active boot/reboot receivers in the app). But that's a separate issue really.

Let me know which others you think might be redundant.

Thanks, I just installed your fork!

There are like 4 re/boot receivers, so I tried disabling these 2:
com.pravera.flutter_foreground_task.service.RebootReceiver
com.pravera.flutter_foreground_task.service.RestartReceiver

and my test alarms still went off after rebooting.
