Maps error on latest Forms + Forms.Maps build

I'm using 1.3.1.0 Forms and Forms.Maps and just can't get the maps working Started an app from scratch. Here is my AndroidManifest.xml:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" android:versionCode="1" android:versionName="1.0" package="com.thehappiesthour.app.android" android:installLocation="auto">

I keep getting an error regarding CameraUpdateFactory. I've had a similar project run fine on older versions (1.2), and have regenerated a unique SHA1 key for the Google API. Only error from the log is:

[Google Maps Android API] Google Play services client version: 6587000
[Google Maps Android API] Google Play services package version: 6594036
[dalvikvm-heap] Grow heap (frag case) to 10.064MB for 1127532-byte allocation

Here is the stack:
