want to show admob interstitial on app start

Question

I integrate the interstitial ad from admob in my application and that is of google play version. I want to show ad on starting of app but it does not work. I have a code in which ad comes up on "onPause", "onResume" etc methods. Is there any way to show ad on starting of app like within 2 second of starting an app. Here is my code for interstitial.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    StartAppAd.init(this, "110342272", "204516610");

    setContentView(R.layout.activity_start);

    // Create the interstitial.
    interstitial = new InterstitialAd(this);
    interstitial.setAdUnitId("ca-app-pub-2869508995487312/2690564381");

    // Create ad request.
    AdRequest adRequest = new AdRequest.Builder().build();

    // Begin loading your interstitial.
    interstitial.loadAd(adRequest);
           }
    @Override
protected void onPause() {
display();
super.onStart();
}

public void display() {
if (interstitial.isLoaded()) {
interstitial.show();
}
}

According to new policies of Admob , interstitial ads are not permitted on start and exiting of app.Your account may be banned if you will violate this policy. Therefore avoid it.

Here's what I created to load interstitial ad when user open the app:

      InterstitialAd interstitial;

private static final String AD_UNIT_ID = "YOUR_AD_UNIT_ID";
private InterstitialAd interstitialAd;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_start);


    interstitialAd = new InterstitialAd(this);

    interstitialAd.setAdUnitId(AD_UNIT_ID);
    AdRequest adRequest = new AdRequest.Builder().build();

    interstitialAd.loadAd(adRequest);

    interstitialAd.setAdListener(new AdListener() {
        @Override
        public void onAdLoaded() {

                if (interstitialAd.isLoaded()) {
                    interstitialAd.show();
                }

        }

        @Override
        public void onAdOpened() {


        }

        @Override
        public void onAdFailedToLoad(int errorCode) {

        }
    });

}
