Facebook SDK for Android throwing ClassNotFound exception

Question

My latest version of the app has been throwing this error occasionally:

Caused by: java.lang.RuntimeException: Parcelable encounteredClassNotFoundException reading a Serializable object (name = com.facebook.friends.constants.FriendRequestMakeRef)

Here is the stack down to the line which causes it:

   at android.os.Parcel.readSerializable(Parcel.java:2148)
   at android.os.Parcel.readValue(Parcel.java:2016)
   at android.os.Parcel.readMapInternal(Parcel.java:2226)
   at android.os.Bundle.unparcel(Bundle.java:223)
   at android.os.Bundle.getString(Bundle.java:1055)
   at android.content.Intent.getStringExtra(Intent.java:4426)

It's being thrown when I do getStringExtra on a Bundle as you can see. It looks like the Facebook SDK is adding an object to the bundle that upon reading, cannot find a class for and then crashes. The string I'm looking for on this line has nothing to do with Facebook.

I haven't changed anything related to the Facebook SDK for a long time, but all of the sudden this is popping up. I attribute it to my switch from the old ANT style compilation to Gradle, as that's the only thing that changed between the older versions and this new version getting the error.

Anyways, I searched around and found literally nothing on this. What's more, I don't blame it for crashing, the Facebook SDK version I'm using doesn't even have a package com.facebook.friends.constants

Has anyone run into this?

Upgrading SDK to the latest version will solve the problem
