这是我的代码,我在做什么,

 if (fragment != null) {
             interstitial.setAdListener(new AdListener() {

             public void onAdLoaded() {

             displayInterstitial();

             }

             public void onAdClosed() {
            FragmentManager fragmentManager = getFragmentManager();
            fragmentManager
                    .beginTransaction()
                    .setCustomAnimations(R.animator.slide_in_left,
                            R.animator.slide_out_right,
                            R.animator.slide_in_left,
                            R.animator.slide_out_right)
                    .replace(R.id.frame_container, fragment)..commitAllowingStateLoss();

            // update selected item and title, then close the
            // drawer

            getActivity().getActionBar().setTitle(Title);
             };

             });

提前致谢.

您获得的错误是由于您在Activity上调用#onSaveInstanceState后尝试执行Fragment操作.即您的活动已被停止并可能被销毁,这无疑是因为广告活动已被显示.当广告关闭时,您的活动将重新启动(甚至可能重新创建),因此您需要在此处进行任何UI操作.

在旁注:

不要从AdListener#onAdLoaded调用displayInterstitial.

这将提供非常糟糕的用户体验,并且当您最不期望它们(例如在您的活动存在之后)出现广告时会导致大量问题.

而是在应用程序的自然断点处调用DisplayInterstitial.
