How put Android native code into c# unity

Hi everyone …
how i can put android native code into c# unity, i need access for example: list contact or camera from my phone… and then i need work with that.

something like:

using UnityEngine; 
public class NewBehaviourScript : MonoBehaviour { 

	void Start () { 
              {JAVA CODE}


There’s no way to do that. You can include native code as a plugin if you have Pro (Desktop) or if you use Mobile platforms.

Try the following repository
