I will get you a stack trace very soon, but in the meantime some more info.
I have had reports from users as well as from crashlytics that the app crashes when users login on multiple different apps, but all apps use the same or very similar code be it a 3.x app or a 5.x app. It seems to be when a user logs in. Other backendless functions seem ok. It is as if it is timing out on login
I use something like this
Backendless user = Backendless.UserService.login(email, password, true);
Anyway this code has been running on my apps for literally years without any problems and then yesterday on multiple apps I was getting numerous crashes. The apps were on 5.x as well as some older ones on 3.x apps. I could replicate the faults myself on installed apps, but was out of the office and couldn’t debug from IDE - I could just see they were crashing… Some of those faults seem to have dissapeared today on the 5.x apps as (my one anyway) seems to work again.
but one remains on and old 3.x app (ID already listed)
I am having to rebuild that old app now in Android Studio so I can get a proper stack trace for you.
