Android 模拟器未启动，显示无效的命令行参数

我在Eclipse制作了一个简单的"Hello World"节目.我没有向Java文件添加任何内容，只在文件main.xml中添加了一个文本视图，如下所示

//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

这表明我的Android Virtual Device(AVD)由于某些原因无法启动.我可以做些什么来解决此问题？
