[Bug]: Amazon + oneSignal crash on start

[Vladeng]

What happened?

We have a problem with Amazon version of our game with an integrated onesignal.

Steps to reproduce?

We did all like an instruction 
https://documentation.onesignal.com/docs/unity-sdk-setup
and
place api_key.txt on Assets/Plugins/Android/ AND Assets/StreamingAssets
our apk: https://www.dropbox.com/s/1n6wqafe058pqv4/do.apk?dl=0

and got crash on start:
