I install eclipse with adt with sdk for android and i can not start emulator. Thank you for help.

Answer 1

Try opening emulator with less device screen size like 3.2'and wait for emulator to launch,on first occasion it might take some time. Emulator with high config and screen size takes ages to open and sometimes does not even launch no matter what. I had the same problem and i opened emulator using small screen resolution and boom it worked. :) Try it.
