am using onesignal 'com.onesignal:OneSignal:3.11.2'

It can be easily reproducible in development environment when sending inapp messages in TOP BANNER & BOTTOM BANNER mode

@gsksarath Thanks for the stack trace, I reviewed our code and I don't see a straightforward ways this could be null. It might be related to how your app is transiting between Activities.

Could you provide the following details so we can take a deeper look?

1. Does the crash happen immediately on startup? If not provide more detail on reproducing

2. Does the crash happen only sometimes or everytime?

3. Does it crash if you rotate the device? (Only a factor if allow rotation in your app)

4. Please enable full OneSignal logging and attach your logcat.

OneSignal.setLogLevel(OneSignal.LOG_LEVEL.VERBOSE, OneSignal.LOG_LEVEL.NONE);
