Answer 1

I Slove it by this step you should delete this file that you can do it .

go to the path :"C:\Users\Administrator.android\avd" and delete all the avd folders files .

try again ,you can get it.

Answer 2

Why this happens

at  com.android.sdklib.internal.avd.AvdManager.parseAvdInfo(AvdManager.java:1616)

The error seems to be in Android SDK library Android Virtual Device Manager. It tries to open a file, and some argument in File constructor is null.

Solution:

I installed the needed plugins again..and it works

What else can be done in similar situations:

1. Plugin damaged -> reinstall the plugin.
2. SDK damaged -> reinstall Android SDK.
3. Wrong version used -> check the used version or update Android SDK.
