Answer 1

Facebook new sdk has been released yesterday. Change your facebook sdk dependency as:

compile 'com.facebook.android:facebook-android-sdk:4.15.0'

Answer 2

My gradle line for Facebook SDK was set to

    compile 'com.facebook.android:facebook-android-sdk:4.+'

So it was pulling the latest SDK that came out on 28th Sept (4.16.0). This version is causing this error. To fix this we added the following lines to <application> tag in manifest file:

tools:node="replace"
tools:replace="android:theme"

This seems to fix it.
