Android 导致窗口泄漏的本机Admob ad

我正在一个活动中显示一个本地广告，该活动使用FragmentContainerView来显示不同的片段。 但是当我使用后退按钮退出应用程序时，我得到了以下错误

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

请帮助我解决此错误。

问题似乎是由新的本机验证程序引起的，当我在清单文件中禁用验证程序时，错误就会消失。因为验证器对于发布版本是自动禁用的。 在清单文件中使用

NATIVE\u AD\u DEBUGGER\u ENABLED

禁用验证器可以解决这两个问题

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