自定義組件和ViewPager問題：「無法實例化活動ComponentInfo」

Question

我試圖使SwipeMenu。我在一個小的測試項目得到了工作，但是當我試圖實現它，我得到以下錯誤：

這裏是我的類：

package com.SverkerSbrg.Spendo.Graphics; 

import com.SverkerSbrg.Spendo.R; 
import com.SverkerSbrg.Spendo.Graphics.TransactionList.*; 

import android.os.Bundle; 
import android.support.v4.app.Fragment; 
import android.support.v4.app.FragmentActivity; 
import android.support.v4.app.FragmentManager; 
import android.support.v4.app.FragmentStatePagerAdapter; 
import android.support.v4.view.PagerAdapter; 
import android.support.v4.view.ViewPager; 

public class SwipeMenu extends FragmentActivity { 

    private ViewPager mPager; 
    private PagerAdapter mPagerAdapter; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.swipe_menu_layout); 

     mPager = (ViewPager) findViewById(R.id.pager); 
     mPagerAdapter = new ScreenSlidePagerAdapter(getSupportFragmentManager()); 
     mPager.setAdapter(mPagerAdapter); 
    } 

    @Override 
    public void onBackPressed() { 
     if (mPager.getCurrentItem() == 0) { 
      // If the user is currently looking at the first step, allow the 
      // system to handle the 
      // Back button. This calls finish() on this activity and pops the 
      // back stack. 
      super.onBackPressed(); 
     } else { 
      // Otherwise, select the previous step. 
      mPager.setCurrentItem(mPager.getCurrentItem() - 1); 
     } 
    } 

    private class ScreenSlidePagerAdapter extends FragmentStatePagerAdapter { 

     public ScreenSlidePagerAdapter(FragmentManager fm) { 
      super(fm); 
     } 

     @Override 
     public Fragment getItem(int position) { 
      return new TransactionList(); 
     } 

     @Override 
     public int getCount() { 
      return 2; 
     } 
    } 
} 

這裏是我的清單：

</manifest> 

所有幫助是極大的讚賞:)

烏爾清單

package="com.SverkerSbrg.Spendo" 

和UR活動課

package com.SverkerSbrg.Spendo.Graphics; 

所以我只好存包的名稱相同。
