Firebase警告显示片段中的非页内广告？

Question

我正在我的应用中实施非页内广告。我正在片段中加载广告并在按钮点击时显示它，并从片段中的'onAdClosed（）'列表器上启动一个活动。

这是我的代码： -

public View onCreateView(....){
        mInterstitialAd = new InterstitialAd(getActivity());
        mInterstitialAd.setAdUnitId(mContext.getString(R.string.admob_ad_unit_id_full_screen));
        mInterstitialAd.loadAd(new AdRequest.Builder().
                addTestDevice("XX_DEVICE_ID").
                build());

mInterstitialAd.setAdListener(new AdListener() {
            @Override
            public void onAdClosed() {
                super.onAdClosed();

            if(condition)
                startactivity(---, ---);

            // loading ad
            mInterstitialAd.loadAd(new AdRequest.Builder().
                        addTestDevice("XX_DEVICE_ID").
                        build());
        }
    }
}

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.mybutton:
                if (mInterstitialAd.isLoaded()) {
                    mInterstitialAd.show();
                } else {
                    startactivity(---, ---);
                }
                break;
        }
    }

除了我每次点击按钮并且广告显示我收到这些警告时，一切都运转正常： -
