Android Admob无法销毁活动

虽然我没有在我的任何设备上看到过更令人沮丧的情况，但我从市场上的用户那里得到了这个堆栈跟踪

java.lang.RuntimeException: Unable to destroy activity

该应用程序是一个由AndEngine GLES1驱动的游戏。它使用XML方法来配置adview，例如在我的主布局中

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<org.anddev.andengine.opengl.view.RenderSurfaceView
android:id="@+id/xmllayoutRenderSurfaceView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_centerInParent="true"
android:gravity="center" />
<com.google.ads.AdView
android:id="@+id/adView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="@id/xmllayoutRenderSurfaceView"
android:layout_centerInParent="true"
ads:adSize="BANNER"
ads:adUnitId="<MyCode>"
ads:loadAdOnCreate="true" />
</RelativeLayout>

我正在使用Admob 6.2.1。它在我手头的每台设备上都能正常工作，包括SG 1和3、华为和Archos。。。所有工作都很好，从横幅和间隙广告显示。有没有其他人遇到过这个问题，或者设法解决了这个问题？任何帮助都将不胜感激

干杯
