Build error for gear vr app involving manifest in mac os

I am getting the following error when trying to build the sample vr assets.

I am using Unity 2017.1.0f3, and trying to deploy to Samsung Galaxy S8+ (which is running Nougat 7.0)

I have followed the suggestion of copying the AndroidManifest-main.xml to the {Assets}/Plugins/Android/ folder in order to override the temp project manifest and I have inserted the following tools:replace="android:theme" and tools:replace="android:debuggable" in the application element, but this has not prevented the error. Is there somewhere else that I need to change or is it possible to set the them and debuggable flags elsewhere to prevent the conflict from occurring?
