AdView 減慢整個應用程序的速度，可能的原因

Question

我在屏幕下方有 WebView + ListView 和 AdView。 WebView 或 ListView 在舊設備（Android 4.0-4.3）上運行非常緩慢，直到 AdView 被加載，然后它才能非常流暢地運行。

Logcat 顯示，AdMob 經常嘗試加載一些令人難以置信的內容，但一直沒有成功，直到..成功，然后應用程序才流暢。 可能是一個原因嗎？ 如何解決？

AdView 是在 Activity.onCreate 方法中創建的。 開始時可見。 http://pastebin.com/xZ7C8WGK

Answer 1

我有一個簡單的動畫，在應用程序啟動時運行，它在我投放 AdMob 廣告之前運行流暢，顯然 AdMob 需要大量資源才能啟動。

所以我的解決方案是等待動畫結束，然后開始加載廣告。

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

Admob 只是啟動緩慢，因此解決了啟動延遲問題。

Answer 2

很可能這是一個問題。 可以通過刪除 AdView 輕松檢查它（如果我理解正確的話）我不知道您的應用程序的具體細節，但我建議您嘗試Crosswalk Project 。

一般來說，使用 Admob 是同步的，但您可以嘗試使用 AsyncTask 來創建它。 或者，您可以嘗試立即投放廣告，但要在一段時間后投放。

我仍然可以建議嘗試使用 Admob的第三方插件。

最后，案例可能是在不穩定的互聯網渠道中。 我能想到的就這些。 我希望一切都會好起來。
