MobileCore 1.0 integration problem

Hello everyone,
I am using mobileCore for app monetization but the problem is since the update of the version to 1.0 methods changed. I put this code but the application exit then reload and when interstitial pop up I can’t close it. If anyone can help me, thanks. Here is the code:

using UnityEngine;
using System.Collections;
using UnityAndroid;

public class SimpleGUI : MonoBehaviour {

public MobilecoreAndroid mobileCore;

// Use this for initialization
void Start () {
	if(mobileCore == null){
		mobileCore = new MobilecoreAndroid("8J2R4UYSQWA3B6X7C99NXK19G2TN6",MobilecoreAndroid.LOGTYPE_PROD, 
		                                   this.gameObject, MobilecoreAndroid.ALL_UNITS);
		
	}

   mobileCore.ShowInterstitial();

}

// Update is called once per frame
void Update () {
}

}

Here is the answer mobile core gave me and that solved my problem:

Please make sure you have the following 2 features integrated in your app:

  1. Back button. To address the Back button problem, please check the “Back button” section of the documentation.

  2. User clicks on ad-units and ‘X’ button.
    Most likely the problem is that click event is not propagated to android correctly.

  • Check if activity tag in the AndroidManifest.xml has the “ForwardNativeEventsToDalvik” meta-data:
