    #2
    Solved every issue I had and got it to run.

    Issue #1: From the post.
    Solution: Copy SDK Licenses from Android Studio to NVPACK SDK.
    Licenses on my ...\NVPACK\android-sdk-windows\licenses\android-sdk-license file:
    8933bad161af4178b1185d1a37fbf41ea5269c55

    Issue #2: Build Failed because of Daydream API
    Solution: Disabled GoogleVR Plugin

    Issue #3: "Failed to open descriptor file error" when running the installed APK on my S7.
