OneSignal 5.1.20 - Android

[michael-winkler]

@jkasten2 Was this fixed in 5.1.20 ?

[jkasten2]

@fanwgwg @amrutkarsuraj @michael-winkler Thanks for reporting, this looks to be a very rare bug introduced in 5.1.19.

Based on the stack traces it looks like this happens if the app is backgrounded very shortly (~10-100ms) after OneSignal.initWithContext is called.

• SessionService.start() was moved to a background thread to prevent some ANRs, however this almost makes this rare race condition possible.

[michael-winkler]

A fix would be great @jkasten2 🙂

[aybarska]

any fixes yet ?

[Samin-roadsurfer]

[SimonFrandi]

We also received a lot of crash information, and the crash indicator suddenly went up. When will it be fixed?
