在解编组时找不到的类: com.startapp.android.publish.banner.banner3d.Banner3D$SavedState？

Question

我使用的是来自StartApp的横幅广告，这给了我标题的例外。

activity_main.xml

<android.support.v4.view.ViewPager 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/pager"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

     <android.support.v4.view.PagerTabStrip
                android:id="@+id/pager_tab_strip"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_gravity="top" />

</android.support.v4.view.ViewPager>

我有三个片段用于填充上面的PageTabStrip

fragment1_layout.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:padding="@dimen/layout_padding"
        android:orientation="vertical" >

    <ListView
            android:id="@+id/list_fragment1"
            android:layout_width="match_parent"
            android:layout_height="0px"
            android:layout_weight="1" />

    <com.startapp.android.publish.banner.Banner
            android:id="@+id/startAppBanner"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="bottom" />

</LinearLayout>

fragments2_layout.xml和fragment3_layout.xml与fragment1_layout.xml完全相同

Fragment1.java

    public class Fragment1 extends SherlockFragment
    {

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) 
        {
            return inflater.inflate(R.layout.fragment1_layout, container, false);
        }
    @Override
    public void onActivityCreated(Bundle savedInstanceState) 
    {
                //Initializing list_fragment1 in fragment1_layout.xml here
    }
}

类似地，我有Fragment2.java和Fragment3.java类

CollectionPagerAdapter.java

class CollectionPagerAdapter extends FragmentStatePagerAdapter 
{
    @Override
    public Fragment getItem(int tabNumber) 
    {
        Fragment fragment = null;

        switch( tabNumber )
        {
            case 0: fragment = new Fragment1();
            break;

            case 1: fragment = new Fragment2();
            break;

            case 2: fragment = new Fragment3();
            break;  
        }

        return fragment;
    }

    @Override
    public int getCount() 
    { 
        return activity.getResources().getInteger( R.integer.number_of_tabs );
    }

    @Override
    public CharSequence getPageTitle(int position) 
    {
        //Returning titles here     
    }
 }

MainActivity.java

    public class MainActivity extends SherlockFragmentActivity
    { 

    @Override
    public void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        //Has to be called before setContentView() method
        StartAppAd.init( this, getString(R.string.my_startapp_developer_id), getString(R.string.my_apps_startapp_id) ); 
        startAppAd = new StartAppAd(this);  //For Interstitial Ads
        setContentView(R.layout.activity_main);
        CollectionPagerAdapter collectionPagerAdapter = new CollectionPagerAdapter( this, getSupportFragmentManager() );
    }

    @Override
    public void onBackPressed() 
    {
        startAppAd.onBackPressed();
        super.onBackPressed();
        Log.d(TAG, "onBackPressed");
    }

    @Override
    protected void onResume() 
    {
        super.onResume();
        startAppAd.onResume();  //For Interstitial Ads
        Log.d(TAG, "onResume");
    }

    @Override
    protected void onPause() 
    {
        super.onPause();
        startAppAd.onPause();   //Makes the Interstitial Ads appear when the user press the 'Home' button on the device
        Log.d(TAG, "onPause");
    }
}

当我运行我的应用程序更新，即，没有以前保存的状态。横幅广告显示在相应的PageTabStrip和一切运行良好。

假设我在Fragement1 PageTabStripe中，按下'Home‘键(以便该应用程序保存其状态)退出我的应用程序，然后在运行其他应用程序(以便在应用程序的MainActivity中执行protected void onDestroy() )之后，在稍后阶段返回。Fragment1 PageTabStrip恢复正常，但是当我滑动到Fragment2 PageTabStrip时，我的应用程序会崩溃，下面的例外情况如下。

同样的事情发生在Fragment3 PageTabStrip，按下'Home‘键离开我的应用程序，稍后再回来。Fragment3 PageTabStrip恢复正常，但当我滑动到Fragment2 PageTabStrip时，我的应用程序会崩溃，例外情况如下。
