问题描述

I have WebView + ListView and AdView below of screen.我在屏幕下方有 WebView + ListView 和 AdView。 WebView or ListView works terrible laggy on older devices (4.0-4.3 Android) until AdView gets loaded, then it works very smoothly. WebView 或 ListView 在旧设备（Android 4.0-4.3）上运行非常缓慢，直到 AdView 被加载，然后它才能非常流畅地运行。

Logcat shows that AdMob try to load something incredibly often with no success until.. success and then app is smooth. Logcat 显示，AdMob 经常尝试加载一些令人难以置信的内容，但一直没有成功，直到..成功，然后应用程序才流畅。 May it be a reason?可能是一个原因吗？ How to fix it?如何解决？

I have a simple animation that runs when the app starts, it used to run smoothly before I put AdMob ads, apparently AdMob needs a lot of resources to start up.我有一个简单的动画，在应用程序启动时运行，它在我投放 AdMob 广告之前运行流畅，显然 AdMob 需要大量资源才能启动。

so my solution was to wait for the animations to end, then start loading the ad.所以我的解决方案是等待动画结束，然后开始加载广告。

Handler handler = new Handler();
handler.postDelayed(new Runnable() {
     @Override
     public void run() {
          AdRequest bannerRequest = new AdRequest.Builder().build();
          mAdView.loadAd(bannerRequest);
     }
},2000);

Admob is only slow at starting up, so this solved the start up lag. Admob 只是启动缓慢，因此解决了启动延迟问题。

Most likely it is a problem.很可能这是一个问题。 It can easily be checked by removing AdView (if I understand you correctly) I do not know the specifics of your application, but I advise you to try Crosswalk Project .可以通过删除 AdView 轻松检查它（如果我理解正确的话）我不知道您的应用程序的具体细节，但我建议您尝试Crosswalk Project 。

In general, work with the Admob to be synchronous, but you can try to use AsyncTask for its creation.一般来说，使用 Admob 是同步的，但您可以尝试使用 AsyncTask 来创建它。 Alternatively, you can try to run ads immediately, but after some time.或者，您可以尝试立即投放广告，但要在一段时间后投放。

Still I can advise to try to use a third-party plug-in for Admob.我仍然可以建议尝试使用 Admob的第三方插件。

Finally, the case may be in an unstable Internet channel.最后，案例可能是在不稳定的互联网渠道中。 That's all I could think of.我能想到的就这些。 I hope that everything will be OK.我希望一切都会好起来。
