Neither AVD nor application show up

Hi!

I already wrote a small application for android before and everything worked nice.
After a week, I came back to android, and AVD doesn't show up anymore.
I think it starts, because it says that it's running when I try to delete it, but it doesn't show up on the screen.
Also, when I try to run application, console doesn't show anything, and nothing happens basically.

I don't know what to do.
I recently upgraded my Ubuntu, I don't know if that might be connected.
But after I did that I redownloaded and reset everything up.

Any help is really appreciated!
Thank you!

My advice to you would be to do the following:

1. Make sure your Ubuntu system is up to-date. Which version are you using anyway?
2. Next, download the Eclipse ADT bundle, the latest version -- that should include everything you need.
3. Try to create a new AVD in the AVD manager and start it. If it doesn't start normally, do you see any outputs in the console or the logcat?

Repeat the process to create avd in Ubuntu. it will work as before
