Android模拟器没有启动，显示出与QUOT;无效的命令行参数＆QUOT;

我取得 Eclipse中一个简单的Hello World程序。我什么都不添加到Java文件，只添加的文件文本视图的main.xml 为

I made a simple "Hello World" program in Eclipse. I added nothing to a Java file and only added a text view in file main.xml as

//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>

而现在，当我运行我的程序它显示在控制台下面。

And now when I run my program it shows the following in the console.

//console output

这显示了我的 Android虚拟设备（AVD）不能由于某种原因开始。我能做些什么来解决这个问题？
