解决方法一：

This is a bug in the ADT Plugin. For a workaround until it is fixed use a NTFS symbolic link.

I have a C: drive for windows 7 and a D: drive for all my work and data. After installing windows 7 I relocate all my special folders from C:\Users\John Doe to D:\John Doe. The ADT Plugin is trying to load the emulator from C: when it and the configure files
are on D: (PANIC: Could not open etc.). NTFS can get the ADT Plugin to read from D: using a NTFS symbolic link. Open a command prompt in C:\Users\John Doe (obviously use your user name), use the mklink command.

mklink /J "C:\Users\John Doe\\.android" "D:\John Doe\\.android"

Now when the ADT plugin is trying to reference .android on C:, NTFS sends the request to D: and the emulator starts correctly.

解决方法二：

If it is not a path issue, then:

Create a environment variable called:

ANDROID_SDK_HOME

and
set it to

C:\Users\Administrator
Open Eclipse > Window > Preferences

and click in

Run/Debug

and
String Substitution Add a new variable called: user.home and set it to

C:\Users\Administrator

Create
an AVD and run it.

Try these steps

Create a environment variable called:

ANDROID_SDK_HOME

and
set it to

C:\Users\<<Administrator>>

Open

Eclipse
> Window > Preferences

, click in

Run/Debug

and

String
Substitution

. Add a new variable called

user.home

and
set it to

C:\Users\<<Administrator>>

Create an AVD and run it.

Note The

<<Administrator>>

means
the name of your Windows account; it is where resides the folder which contains your

.android

directory

An android project member says here:

As a work-around, you can define the environment variable ANDROID_SDK_HOME to point to the directory containing your .android directory. The emulator and SDK Manager will pick it up properly.

Also you should check that the AVD is created in the location D:\NN\.android\avd (check in your screenshoots, just above the list of AVD, the path in List of existin Android Virtual Devices).
