I am new to this, but followed all the steps and done research on other sites to get this working.
I tried to export the mobile template included in the to my developer mode Moto G phone.
It after a while finially exported, but it did not load.
When I Launch on my phone, which option do I choose for the phone?
It worked.
What I did not see in any tutorials (new to Andriod/other than PC), is that it creates a Icon/APP called UE4Game, where you place while connected after it says Deploy.
Hope this will be a good reference for all the the future.
