Facebook广告错误：您无法在状态LOADING中调用广告的show（）

Question

我正在按照他们的官方documentation将Facebook广告整合到我的应用程序中。但是当我运行我的应用程序时，我得到以下异常

java.lang.IllegalStateException: You can't call show() for ad in state LOADING. You can change Integration Error mode by setting AdSettings.setIntegrationErrorMode()

以下是我的代码

private com.facebook.ads.InterstitialAd fbInterstitialAd;
fbInterstitialAd = new com.facebook.ads.InterstitialAd(this, getString(R.string.fb_interstitial_ad_id));
fbInterstitialAd.loadAd();

我在下面展示它

if (fbInterstitialAd.isAdLoaded() && !fbInterstitialAd.isAdInvalidated()) {
fbInterstitialAd.show();//This line causes the crash

这是我在build.gradle中添加的依赖项

implementation 'com.facebook.android:audience-network-sdk:5.+'

Answer 1

您正在使用错误的依赖项。替换以下依赖项：

implementation 'com.facebook.android:audience-network-sdk:5.+'

同

implementation 'com.facebook.android:audience-network-sdk:5.0.1'

Answer 2

嗨：您需要检查广告是否为空，如果在展示之前已加载广告：

if(fbInterstitialAd != null && fbInterstitialAd.isAdLoaded()) fbInterstitialAd.show();

Answer 3

我将facebook广告从5.0.1更新为5.3.1，我也有同样的错误：

java.lang.IllegalStateException: You can't call load() for ad in state LOADING. Previous states: LOADING << CREATED. You can change Integration Error mode by setting AdSettings.setIntegrationErrorMode()

当您尝试在上一个广告加载时加载新广告时，会发生此错误。他们在编写代码时吸烟了什么？他们应该将错误重定向到“onError”方法，但他们决定抛出IllegalStateException

我的解决方案并不优雅，但它的工作原理是：

// load the ad
public void load() {
    if (interstitialAd != null) {
        try {
            interstitialAd.loadAd();
        } catch (Throwable e) {
            // Do nothing, just skip and wait for ad loading
        }
    }
}

// show the ad
public void show() {
    if (interstitialAd != null && interstitialAd.isAdLoaded()) {
        try {
            interstitialAd.show();
        } catch (Throwable e) {
            // Do nothing, just skip and wait for ad loading
        }
    }
}

Answer 4

 fb_interstitialAd.setAdListener(new InterstitialAdListener() {
        @Override
        public void onInterstitialDisplayed(Ad ad) {
            Toast.makeText(VideoStatusActivity.this, "Display", 
          Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onInterstitialDismissed(Ad ad) {
            fb_interstitialAd.loadAd();
        }

        @Override
        public void onError(Ad ad, AdError adError) {

        }

        @Override
        public void onAdLoaded(Ad ad) {

        }

        @Override
        public void onAdClicked(Ad ad) {

        }

        @Override
        public void onLoggingImpression(Ad ad) {

        }
    });
