If-else not work properly when use Facebook Interstitial Ad, interstitial ad shows automatically

Question

if-else used for check is interstitial ad loaded or not. If not loaded then startIntent by else. (code is below).

Problem(see Logcat): If Ad not loaded then second activity open via else part then after some seconds AdListener run that is in if part Interstitial ad pop-up automatically. [this is against to Ad policy]

Here else part run then new activity open. Then automatically run AdListener that in Ifpart.(like:onAdLoaded, onLoggingImpression,onInterstitialDismissed)

@Override
    public void onClick(View v) {
        switch (v.getId()) {

            case R.id.btn1Home:
                if (interstitialAd.isAdLoaded()) {
                    Log.e(TAG, "===== btn 1: if part running");
                    interstitialAd=new InterstitialAd(this,"166868475011030_166000348414076");
                    interstitialAdListener=new InterstitialAdListener(){
                        @Override public void onInterstitialDisplayed(Ad ad){}
                        @Override public void onInterstitialDismissed(Ad ad){
                            Log.e(TAG, "===== Ad dismissed.");
                            Intent intent1btn=new Intent(HomeActivity.this,page1activity.class);
                            startActivity(intent1btn);}
                        @Override public void onError(Ad ad,AdError adError){}
                        @Override public void onAdLoaded(Ad ad){
                            Log.e(TAG, "===== AdListener : Ad loaded and then show.");
                            interstitialAd.show();}
                        @Override public void onAdClicked(Ad ad){}
                        @Override public void onLoggingImpression(Ad ad){Log.e(TAG, "===== loggin impression");}};
                    // For auto play video ads, it's recommended to load the ad
                    // at least 30 seconds before it is shown
                    interstitialAd.loadAd(interstitialAd.buildLoadAdConfig().withAdListener(interstitialAdListener).build());

                }else {
                        Log.e(TAG, "===== BTN 1 ELSE PART");
                        if (!interstitialAd.isAdLoaded()) {
                            interstitialAd.loadAd();
                            Intent intent1btn = new Intent(HomeActivity.this, page1activity.class);
                            startActivity(intent1btn);
                        }
                }

                break;

How can i solve this facebook interstitial ad problem?

Answer 1

I solve this problem:

Do not call interstitialAd.show() in onAdLoaded(Ad ad).

It call just after before AdListener mean before Log.e(TAG, "===== btn 1: if part running")
