[Bug]: OneSignalUserDefaults Crash Take II
What happened?
The crash I reported in #1365 is still present in the 5.1.6 release. I’m reporting it again here because the previous issue was closed.
Steps to reproduce?
No idea. This is a remote crash report from Crashlytics.
What did you expect to happen?
The library should not cause a crash, regardless of what I may be doing wrong in using it.

Hi @danhalliday I followed up on your other stacktrace reports.
I am not sure how these crashes could be happening, so I am still investigating.
Any additional information you can share will be helpful:
- Do you have updated data on frequency of these crash reports?
- Do you have data if the app is in the background or foreground?
- Do you have information about the memory usage or state of the memory at time of the crash? One possibility I am considering is the app being out of memory at the time we are saving information. Particularly if you know that there is high memory usage in the app already.
I’m afraid my team has decided to drop OneSignal on the basis of these crashes, so I can’t devote any more time to investigating. But briefly:
- It’s about the same still, being roughly 1% of both users and sessions.
- It’s all foreground.
- I don’t have good data on that, all I have is the Crashlytics reports. I couldn’t discount something like that. But in general this app is not using a lot of memory.
Hi there @nan-li,
We are getting similar crashes in our production version of the app. Here is some data from Crashlytics:
