Android 安卓系统-整合facebook受众网络后崩溃率上升。如何解决这个问题？

我们在一个月前集成了风扇，它开始显示出崩溃率的巨大增长

我们的应用程序包含横幅广告、插入式广告和本地广告

以下是有关此崩溃的详细日志：

编辑1： 以下是VideoDetailActivity中插入式广告的代码：

interstitialAd = new com.facebook.ads.InterstitialAd(mContext,

getResources().getString(R.string.fb_interstitial_id));
            interstitialAd.loadAd();
            try {
                interstitialAd.setAdListener(new AbstractAdListener() {
                    @Override
                    public void onAdLoaded(Ad ad) {
                        super.onAdLoaded(ad);
                        String isShow = mFirebaseRemoteConfig.getString("show_vs");
                        if (isShow.equalsIgnoreCase("true")) {
                            if (System.currentTimeMillis() - QuotesUtils.getLastSavedDateForAds(mContext) >
                                    Long.parseLong(mFirebaseRemoteConfig.getString("duration"))) {
                                if (interstitialAd.isAdLoaded())
                                    interstitialAd.show();

                                QuotesUtils.setLastSavedDateForAds(mContext, System.currentTimeMillis());
                            }
                        }
                    }
                });
            } catch (Exception e) {
                e.printStackTrace();
                Crashlytics.log("FBAd>>>" + e.getMessage());
            }

adViewFB = new com.facebook.ads.AdView(mContext,getResources().getString(R.string.fb_banner_id),AdSize.BANNER_HEIGHT_50);
            final LinearLayout adContainer = 
findViewById(R.id.banner_container);
            adContainer.addView(adViewFB);
            adViewFB.loadAd();
            adViewFB.setAdListener(new AbstractAdListener() {
                @Override
                public void onAdLoaded(Ad ad) {
                    super.onAdLoaded(ad);
                    adContainer.setVisibility(View.VISIBLE);
                }
            });

以下是VideoDetailActivity的横幅广告代码：

interstitialAd = new com.facebook.ads.InterstitialAd(mContext,

getResources().getString(R.string.fb_interstitial_id));
            interstitialAd.loadAd();
            try {
                interstitialAd.setAdListener(new AbstractAdListener() {
                    @Override
                    public void onAdLoaded(Ad ad) {
                        super.onAdLoaded(ad);
                        String isShow = mFirebaseRemoteConfig.getString("show_vs");
                        if (isShow.equalsIgnoreCase("true")) {
                            if (System.currentTimeMillis() - QuotesUtils.getLastSavedDateForAds(mContext) >
                                    Long.parseLong(mFirebaseRemoteConfig.getString("duration"))) {
                                if (interstitialAd.isAdLoaded())
                                    interstitialAd.show();

                                QuotesUtils.setLastSavedDateForAds(mContext, System.currentTimeMillis());
                            }
                        }
                    }
                });
            } catch (Exception e) {
                e.printStackTrace();
                Crashlytics.log("FBAd>>>" + e.getMessage());
            }

adViewFB = new com.facebook.ads.AdView(mContext,getResources().getString(R.string.fb_banner_id),AdSize.BANNER_HEIGHT_50);
            final LinearLayout adContainer = 
findViewById(R.id.banner_container);
            adContainer.addView(adViewFB);
            adViewFB.loadAd();
            adViewFB.setAdListener(new AbstractAdListener() {
                @Override
                public void onAdLoaded(Ad ad) {
                    super.onAdLoaded(ad);
                    adContainer.setVisibility(View.VISIBLE);
                }
            });
