錯誤膨脹類android.support.v4.view.ViewPager

我一直在試圖爲我的應用程序創建一個傳呼機<uses-sdk android:minSdkVersion="10" android:targetSdkVersion="15" />我寫了我的代碼根據this blog post。錯誤膨脹類android.support.v4.view.ViewPager

XML的尋呼機活動：

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical" > 

    <android.support.v4.view.ViewPager 
     android:id="@+id/instructionsViewPager" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" /> 
</LinearLayout>

代碼適配器：

public class MyPagerAdapter extends PagerAdapter { 

    @Override 
    public int getCount() { 
     // TODO Auto-generated method stub 
     return 2; 
    } 

    @Override 
    public boolean isViewFromObject(View arg0, Object arg1) { 
     return (arg0 == ((View) arg1)); 
    } 

    @Override 
    public void destroyItem(ViewGroup container, int position, Object object) { 
     ((ViewPager) container).removeView((View) object); 
    } 

    @Override 
    public Object instantiateItem(ViewGroup container, int position) { 
     LayoutInflater inflater = (LayoutInflater) container.getContext() 
       .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     int resId = 0; 
     switch (position) { 
     case 1: 
      resId = R.layout.instructions_page1; 
      break; 
     case 2: 
      resId = R.layout.instructions_page2; 
      break; 
     } 
     View view = inflater.inflate(resId, null); 
     ((ViewPager) container).addView(view, 0); 
     return view; 
    } 
}

規範活動

public class Instructions extends Activity { 

    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.instructions); 

     MyPagerAdapter adapter = new MyPagerAdapter(); 
     ViewPager pager = (ViewPager) findViewById(R.id.instructionsViewPager); 
     pager.setAdapter(adapter); 
     pager.setCurrentItem(0); 
    } 
}

出於某種原因，當我運行這個程序，我得到這個下面的錯誤列表：

所以，我知道它的失敗，因爲我使用的是android.support.v4.view.ViewPager，我試着用，玩，改變爲純ViewPager和進口android.support.v13但它沒有幫助...

有關如何解決這個問題的任何想法？
