Generating a distributable VR experience outside of Google Play Store

Hi Folks,

I use Unreal to generate custom enterprise VR experiences for clients - generally product showcases or simple environment walkthroughs.

I am looking into publishing my experiences to Android but can’t seem to wrap my head around how to make that experience easily distributable to my clients without them having to install background programs on their laptop and hook their android device up to install the experience via the .bat file I publish from Unreal.

Is there an alternative way to publish from Unreal wherein I just have a .apk experience install file I can share to a client that they can then easily install on an android device?

Any help is much appreciated.

P.S. A novice user of unreal more in tune with developing experiences for the HTC Vive headsets - This is my first dive into the world of Android development.

Cheers.
