我在屏幕下方有WebView + ListView和AdView。在AdView加载之前，WebView或ListView在老设备(安卓4.0-4.3android)上的工作非常滞后，然后它就能非常顺利地工作。

Logcat显示，AdMob非常频繁地尝试加载某些内容，但都没有成功，直到..成功之后，应用程序就会变得顺畅。这可能是一个原因吗？如何修复它？

我有一个简单的动画，在应用程序启动时运行，它在我放置AdMob广告之前运行得很流畅，显然AdMob需要很多资源才能启动。

所以我的解决方案是等待动画结束，然后开始加载广告。

代码语言：javascript
运行
复制
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
     @Override
     public void run() {
          AdRequest bannerRequest = new AdRequest.Builder().build();
          mAdView.loadAd(bannerRequest);
     }
},2000);

Admob只在启动时很慢，所以这解决了启动滞后的问题。

这很可能是一个问题。通过删除AdView可以很容易地检查到它(如果我理解正确的话)我不知道您的应用程序的细节，但我建议您尝试Crosswalk Project。

一般来说，使用Admob是同步的，但是您可以尝试使用AsyncTask创建它。或者，您可以尝试立即运行广告，但要过一段时间。

尽管如此，我仍然可以建议尝试使用Admob的third-party plug-in。

最后，这种情况可能发生在一个不稳定的互联网渠道。这就是我能想到的一切。我希望一切都会好起来。
