Android Emulator for Ubuntu 12.04
What system are you running the emulator on? At the moment, it just seems like your system is probably too slow to run the emulator. The emulator is very resource intensive, and unless you have a high end machine it's going to be very slow.

For the start, you'd want to start with a smaller screen resolution. Tablet-sized screen resolution is practically impossible to emulate unless you have a very high-end machine, try WQVGA size. Next check how much RAM you allocate for the virtual machine, if it exceeds the amount of free RAM you usually have when you don't have the emulator running, then it's going to be very slow due to heavy swapping. Also, close other applications running on the system to free up resources.
