Error building player with project that includes the Facebook SDK

I'm currently trying to build my project which includes the latest version of the Facebook SDK (7.11.0). I'm trying to build just a simple project on multiple versions of unity - 5.6.1, 5.6.5 and 2017.3.1 and all of them are giving me the same issues.

On trying to build to a device I get the "Error building Player: Your Android setup is not correct. See Settings in Facebook menu.".

 Your Android setup is not correct. See Settings in Facebook menu.
 UnityEngine.Debug:LogError(Object)
 Facebook.Unity.Editor.XCodePostProcess:OnPostProcessBuild(BuildTarget, String)
 UnityEditor.BuildPlayerWindow:BuildPlayerAndRun()

It still creates an APK however when I try to put this on a device it instantly crashes with a fatal exception when trying to login using Facebook.The error is caused by:

 3-01 12:53:40.350: E/AndroidRuntime(4277): Caused by: java.lang.NoClassDefFoundError: Failed resolution of: Lcom/facebook/FacebookActivity;

If I look at the Facebook Settings menu I can't see any errors other than a warning that it's missing the android debug keystore however I know this is there as I can see it. I've tried deleting it and using Android Studio to create a new one to no avail and I've also used keytool to manually generate one - still says it's missing and it doesn't seem to matter which version of Unity. I've seen some people reference changing a CS file in the SDK to fix this but I don't seem to have the CS files in the Facebook SDK to do this.
