Facebook SDK throws ExceptionInInitializerError in ActivateApp on Android device. Can it bring the app down?

I've just integrated the Facebook SDK to track Ad App Install. It seemed working so I've deployed the app on Google Play. Anyway, I got an error in my log from some user's device. It was thrown calling FB.ActivateApp(), in fact with the exception of FB.Init(), that is the only code from the SDK I use.

My concern is if it is bringing the app down or not (if it spoils lunching of the app). I wished to find how UnityEngine.AndroidJNISafe.CheckException () to estimate if the exception is handled without causing the app to crash, but I could not find any reference.

Any comments about

1. damage by the exception

2. cause of the exception

3. the exception handling

are most welcome. Cheers
