Question

我正在实施谷歌提供的原生广告代码.这样做还可以google

广告单元ID ADMOB_AD_UNIT_ID ="ca-app-pub-3940256099942544/2247696110"

但当我用我的id替换它没有显示广告和执行onAdFailedToLoad方法并且 无法加载原生广告:0错误.

I tried two different ad unit id but it didn't load ad.

so what should I do??please help me 

我试过下面的代码

final LayoutInflater li = (LayoutInflater) appContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            AdLoader.Builder builder = new AdLoader.Builder(appContext, Global.ADMOB_AD_UNIT_ID);

            builder.forContentAd(new NativeContentAd.OnContentAdLoadedListener() {
                @Override
                public void onContentAdLoaded(NativeContentAd ad) {
                    //viewHolder.rlnativead.setVisibility(View.VISIBLE);
                    NativeContentAdView adView = (NativeContentAdView)li
                            .inflate(R.layout.ad_content, null);
                    populateContentAdView(ad, adView);
                    viewHolder.fl_adplaceholder.removeAllViews();
                    viewHolder.fl_adplaceholder.addView(adView);
                }
            });

            AdLoader adLoader = builder.withAdListener(new AdListener() {
                @Override
                public void onAdFailedToLoad(int errorCode) {
//                  Toast.makeText(appContext, "Failed to load native ad: "
//                          + errorCode, Toast.LENGTH_SHORT).show();
                    Log.e("Call List adapter","Failed to load native ad: "+errorCode);
                }
            }).build();

            adLoader.loadAd(new AdRequest.Builder().build());

请添加至少一台测试设备并尝试，它可能会对您有所帮助，如下所示，

AdRequest adRequest = new AdRequest.Builder() .addTestDevice("SEE_YOUR_LOGCAT_TO_GET_YOUR_DEVICE_ID") .build();
