我在Eclipse中制作了一个简单的“Hello World”程序。我没有在Java文件中添加任何内容，只是在文件main.xml中添加了一个文本视图。
//main.xml file
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Hello World"
/>
</LinearLayout>
现在当我运行我的程序时，它会在控制台中显示以下内容。
//console output

这说明我的Android虚拟设备（AVD）由于某些原因无法启动。我该怎么办才能解决这个问题？
