Hope someone could fix it.

It seems like your app's storage of alarm events somehow got corrupted. I assume clearing data let you start up the app again? What kinds/how many alarms and timers did you have?

Looks like #514 may have had a similar issue. For future reference you can export (and import) settings.

Either way, I think we can do a tmp write + rename strategy for all writes, since I think android can kill an app at any moment for memory purposes and it would protect against corruption from a partial write. Also we can at least have a graceful degradation where if we can't load a file, we continue on and display an error

EDIT: it looks like alarm_event's is purely just for the history log, so there's very minimal degradation in this case. But I assume this corruption can happen to the actual alarm storage file as well. And there is a a synchronous version of the function that crashes that gracefully degrades already.

Yes Clearing data did work. But just in a few weeks, the app won't start again. I have 7 alarms(4 of them enabled) and 4 timers(none enabled). That's not much right?

No it's not. Though I have heard Honor devices tend to have pretty memory management for battery optimization.

Regardless, I've generated a potential fix, feel free to try it out with one of the 2 recent Robust Serialization builds in my fork here. It should support importing data if you export it from your app, but probably won't let you update over it.

If it works, or helps #514 then I'll submit a Pull Request.
