Can you read me? VR Controller for android

Hello World! I’m a complete NEWBIE or noob whatever, i was wondering if there is any tutorials on how to set up UNITY to make VR-Games from the ground( meaning no UNITY and no plug ins “0”)

Can I make any kind of game with UNITY and when I’m done add the Virtual Reality Feature?(camera)

Can I add specific controls for UNITY, for example a wireless mouse?

Can I add a multiplayer options after the app is made?

Can I add a browser, video, picture, etc…?

Can I add extra Items without making an update? ( a feature from the app that lets me or customers upload certain 3D objects).

I want to make a house with a movie theater connected to the files i decide, the rest of the house with 3D objects the player wants to show off(things you have in real life), add a browser that can pop up any time and ultimately a multiplayer set up so that people in my friend list can join. All this controlled by a wireless mouse. very important to be a wireless mouse, is part of the business model. ANYONE willing to help me?

Look at the google card API or the Dive VR API.

You can use a bluetooth wireless controller.
