Question

我尝试通过异步任务加载Admob插页式广告，如下所示：

private class AdLoaderTask extends AsyncTask<InterstitialAd, Integer, InterstitialAd> {

    InterstitialAd mLocalInterstitialAd;

    protected InterstitialAd doInBackground(InterstitialAd... ads) {
          mLocalInterstitialAd = ads[0];
        AdRequest.Builder builder = new AdRequest.Builder();
        if (BuildConfig.DEBUG) {
              builder.addTestDevice("XXXX");
        }
          AdRequest adRequest = builder.build();
        mLocalInterstitialAd.loadAd(adRequest);
        return mLocalInterstitialAd;
    }
    protected void onPostExecute(Long result) {
        if (mLocalInterstitialAd.isLoaded()) {
            setLoadedInterstitialAd(mLocalInterstitialAd);
        } else {
            loadInterstitialAd(mLocalInterstitialAd);
        }
    }

}

我得到了这个例外：

这是否意味着无法通过AsyncTask加载广告，即使任务本身是从UI线程执行的？

如何解决这个问题？ MobileAds.initialize, setAdUnitId 执行似乎可以在AsyncTask中使用。我错过了什么吗？不使用AsyncTask时，广告加载正常。可以加载Service？

请勿尝试使用AsyncTask; admob异步加载广告，并包含AdListener课程，您可以将其扩展为接收onAdLoaded()，onAdFailedToLoad()等的回调。请参阅https://developers.google.com/android/reference/com/google/android/gms/ads/package-summary

Admob插页式广告使用AsyncTask失败
