The Android emulator is not starting, showing “invalid command-line parameter”

by

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>

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

//console output

This shows my Android Virtual Device (AVD) could not start due to some reason. What can I do to fix this problem?
