android - 原生 Admob 广告导致窗口泄漏

Question

我在具有 FragmentContainerView 的 Activity 中显示原生广告以显示不同的 fragment 。
但是当我使用后退按钮退出应用程序时，我收到以下错误

E/WindowManager: android.view.WindowLeaked: Activity com.status.statusdownload.views.MainActivity has leaked window com.google.android.gms.internal.ads.zzbft{4119d98 I.E...... ......I. 0,0-840,0} that was originally added here

我已经按照官方文档 ( https://developers.google.com/admob/android/native/start) 销毁了对原生广告的引用

if (isDestroyed) {
                    unifiedNativeAd.destroy()
                    return@forNativeAd
                }

请帮我解决这个错误。

接受的答案是正确的。但如果有人不知道它在 list 中的外观:

<manifest>
  ...
  <application>
    ...
    <meta-data 
        android:name="com.google.android.gms.ads.flag.NATIVE_AD_DEBUGGER_ENABLED"
        android:value="false" />
  </application>
</manifest>
