Java NoClassDef使用FragmentPagerAdapter发现viewpager适配器错误

我正在尝试用TabStrib实现要在viewpager中使用的片段，我在片段导入方面遇到了问题，所以我不太确定是否存在任何问题

以下是我的作品：

 package com.dev.lhexpress;
    import android.app.Activity;
    import android.app.Fragment;
    import android.app.FragmentManager;
    import android.os.AsyncTask;
    import android.os.Bundle;
    import android.support.v13.app.FragmentPagerAdapter;
    import android.support.v4.view.ViewPager;
    import android.util.Log;

    public class ExpressSlideActivity extends Activity {

        ExpressFragmentAdapter adapterViewPager;
        ViewPager vpPager;
        FragmentManager fm;

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.express_screen_slide);
            vpPager = (ViewPager) findViewById(R.id.express_pager);
            adapterViewPager = new ExpressFragmentAdapter(getFragmentManager());
            vpPager.setAdapter(adapterViewPager);

        }


        public static class ExpressFragmentAdapter extends FragmentPagerAdapter {
                private static int NUM_ITEMS = 3;

                public ExpressFragmentAdapter(FragmentManager fm) {
                    super(fm);

                }

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

                // Returns the fragment to display for that page
                @Override
                public Fragment getItem(int position) {
                    switch (position) {
                    case 0: 
                        return GeneralFragment.newInstance(0, "General");
                    case 1: 
                        return FavoritesFragment.newInstance(1, "Favoritos");
                    case 2: 
                        return HistoryFragment.newInstance(2, "Historial");
                    default:
                        return null;
                    }
                }

                // Returns the page title for the top indicator
                @Override
                public CharSequence getPageTitle(int position) {
                    return "Page " + position;
                }

            }
    }`

这是我正在运行的日志：

如果有人能帮我，我会非常感激的，我的心都快晕过去了

你们班的软件包在哪里？对不起，我没把它放进去，它在导入软件包com.dev.lhexpress之前；此错误：

java.lang.NoClassDefFoundError:com.dev.lhexpress.ExpressSlideActivity$ExpressFragmentAdapter

，您的

ExpressFragmentAdapter

在哪里？你能告诉我们项目结构吗？
