Q:

Getting error in starting Emulator

When I run my application, I am getting an error. The error is:

invalid command-line parameter:
  sw\android-sdk-windows\tools/emulator-arm.exe. Hint: use '@foo' to
  launch a virtual device named 'foo'. Please use -help for more
  information

What can I do to fix this?

A:

This is because your sdk path in eclipse contains "Program Files", which contains space. Instead of "Program Files" do it PROGRA~1. This should solve the issue.
EDITED
To find the small names of your directories - 
Open a command prompt go to your parent directory and fire this command - DIR/X and you will get list of small names for all of your directories. Replace any name with space with the name you get here.
