HelloCardboard sample :sdk not visible in Gradle

I am trying to run the Google Cardboard sample by following their guide: https://developers.google.com/cardboard/develop/c/quickstart

However, I run into the same error mentioned in this guide. Their solution was:

You should click the "assemble" option under ":sdk", not the one under ":hellocardboard-android".

As shown below:

The following is the image of my window. I don't have the :hellocardboard-android or :sdk folders, just Tasks.

So, is this the right assemble to be running? I am not sure how to see the other folders mentioned. If you have any clarifying questions let me know!

My full error:

FAILURE: Build failed with an exception.

• What went wrong: Execution failed for task ':hellocardboard-android:externalNativeBuildDebug'.

Build command failed. Error while executing process C:\Users\Jonah\AppData\Local\Android\Sdk\cmake\3.10.2.4988404\bin\ninja.exe with arguments {-C O:\Dordt University Campus\hellocardboard-android.cxx\cmake\debug\armeabi-v7a cardboard_jni} ninja: Entering directory `O:\Dordt University Campus\hellocardboard-android.cxx\cmake\debug\armeabi-v7a'

ninja: error: '../../../../libraries/jni/armeabi-v7a/libcardboard_api.so', needed by '../../../../build/intermediates/cmake/debug/obj/armeabi-v7a/libcardboard_jni.so', missing and no known rule to make it

It appears the problem had to do with the path having spaces, moving the project caused the proper folders to appear in the Gradle window.
