一、AdLoader$Builder广告构建ANR

at com.xxx.xx.adc.process.displaying.AdDisplayingProcess.loadAd (AdDisplayingProcess.java:223)
结合日志查看GoNativeAd代码，逻辑如下：
public void load{
...
mAdLoader = new AdLoader.Builder(context, id)
.forNativeAd(nativeAd -> {
mNativeAd = nativeAd;
...
})
.withAdListener().build();
...
}
可知最终阻塞点为AdLoader.Builder，由于Google广告源码混淆了，通过调用堆栈追踪，其内部执行了数据耗时操作：
查看Google广告官方Demo相关issue问题：
https://groups.google.com/g/google-admob-ads-sdk/c/fXW1yZnGt6g/m/H_YTBDVhAQAJ
由issue也可以验证，AdLoader$Builder的创建为耗时方法，应该放到后台子线程进行。
故修改方案为将AdLoader$Builder放到子线程中创建，创建完成后再回到主线程使用。
二、AdView布局动态创建案例

日志分析可知最终阻塞点为LayoutInflater，结合业务分析，GoAnchorAd调用比较频繁：
public class GoAnchorAd extends GoAd {
public void render(Activity activity, String adSpaceName) {
...
AdView mAdView = (AdView) LayoutInflater.from(activity).inflate(R.layout.ad_content_container, null);
mAdView.setAdType(AdConfig.AD_SOURCE_GOOGLE);
mAdView.setSpaceName(adSpaceName);
NativeAdView nativeAdView = (NativeAdView) LayoutInflater.from(activity)
.inflate(AdConfig.getLayoutResId(adSpaceName, AdConfig.AD_SOURCE_GOOGLE), null);
nativeAdView.setHeadlineView(nativeAdView.findViewById(R.id.native_title));
...
}
广告数据请求回来，回调这里，由于调用比较频繁，每次inflater低端机上Binder资源不足，容易阻塞住，可以换一种思路，改为Java直接new出来AdView。修改后：
public class GoAnchorAd extends GoAd {
public void render(Activity activity, String adSpaceName) {
...
AdView mAdView = new AdView(activity);
mAdView.setAdType(AdConfig.AD_SOURCE_GOOGLE);
mAdView.setSpaceName(adSpaceName);
NativeAdView nativeAdView = (NativeAdView) LayoutInflater.from(activity)
.inflate(AdConfig.getLayoutResId(adSpaceName, AdConfig.AD_SOURCE_GOOGLE), null);
nativeAdView.setHeadlineView(nativeAdView.findViewById(R.id.native_title));
...
}
该inflater问题得以解决。
