How to solve AndroidEclipse PANIC Could not open

Here i am going to discuss about how to solve problem AndroidEclipse PANIC Could not open .

Sometime when we are tring to run Android Eclipse,then we get  the following error

[2013-10-1010:10:10 – Test2] Android Launch!
[2013-10-1010:10:10  – Test2] adb is running normally.
[2013-10-1010:10:10  – Test2] Performing com.example.test2.MainActivity activity launch
[2013-10-1010:10:10  – Test2] Launching a new emulator with Virtual Device ‘dev1’
[2013-10-1010:10:10  – Emulator] PANIC: Could not open: dev1

because of this error  we cannot start the emulated device. It keeps saying PANIC Cannot start device... as below screenshot.

For this problem,we can do the following step:

Step:1

Open location of virtual device in  computer.For example given below

 

Step:2

Open Android Eclipse and navigate through the following setup,

Eclipse > Window > Preferences and click in Run/Debug and String Substitution

Add a new variable called: user.home and set it to Virtual device location as per screenshot (D:\Users\Administrator Create an AVD )

Step:3

Set Environment variable

Open MyComputer properties:>go to advanced option and create new system variable:

Variable Name:ANDROID_SDK_HOME 

Variable Value:D:\Users\Administrator (location of virtual device)

and finally run it,if it is not working just restart the system,it will work.If you have any problem or queries with this above step,write comment
