Android 二进制XML文件行#4:<；项目>；标签需要一个'；持续时间'；属性

我是android编程的新手。我正在尝试使用eclipse IDE在运行WindowsVista x64位的计算机上创建一个4选项卡应用程序。在做了一些彻底的研究之后，我偶然发现了创建4个选项卡应用程序的教程。我严格按照说明进行操作，在必要时对其进行修改以进行申请

当我试图在安卓姜饼2.3.3模拟器中启动它时，我一直被迫退出。我做错了什么？欢迎所有建议。提前谢谢

这是我的MainActivity.java代码（请记住，额外的导入是为了将来的目的）

这是我的activity_main.xml代码

<?xml version="1.0" encoding="utf-8"?>

<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/tabhost"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <LinearLayout
        android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:padding="0dp">

        <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:padding="0dp" />

        <TabWidget
            android:id="@android:id/tabs"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="bottom" />
    </LinearLayout>
</TabHost>

它们对应的布局xml文件中的代码如下所示

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_favorites);
    }
}

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

</RelativeLayout>

这是当应用程序试图在模拟器中启动时，我在logcat中得到的错误信息
