Apps emulator does not show up

[gracy]

I tested a helloworld android program last 6 months ago and that program worked and I did not continue to learn that.
Now I started to learn that and tried to learn that program again. But the emulator does not show up.
So I did all the necessay steps from the starts and wrote a new program.
But the emulator still does not show up.
What is the problem?

Assuming you are using Eclipse, can you manually launch an emulator from Eclipse > Window > Android SDK and AVD Manager?

 

[gracy]

No, I can't.
I go Android SDK and AVD Manager and chose one of the virtual device and click start button.
Then a window with the title "Starting Android Emulator" appeared for a second and disappered. But no emulator show up.

Have you tried creating a new emulator using the Android SDK & AVD Manager?

How to create a new emulator using the Android SDK & AVD Manager?
I know nothing about Android. I am just testing , as a first step, the helloworld program from a tutorial that provides step by step instruction.
I cannot carry on without an emulator.
Can the reason be because of the virus of my laptop? Is it possible?

If you are using the latest SDK, there should be a 'new' button.

 

[gracy]

yes. there is a new button and I have a created a new one. But it does not work.

My next step would be to purge your computer of the SDK and possibly Eclipse and do a fresh install.
