Hello,
The crash is happening as you have excluded the android support library v4 from the build which is required to process an incoming OneSignal notification.
If you’re using 'com.phonegap.plugins.facebookconnect'
in your project I recommend removing it and add 'cordova-plugin-facebook4'
instead. I also recommend you follow our Clean Build instructions to make sure you don’t have any parts left from other removed plugins.
Let us know if you’re still seeing an issue after this.
Thanks.
