invalid command-line parameter: Files.The cause of this is that spaces are not allowed in the SDK location path. If you just installed the SDK to the default location (i.e. "C:\Program Files(x86)\Android\android-sdk"), this problem will definitely occur.
Hint: use '@foo' to launch a virtual device named 'foo'.

For Eclipse users, you can solve it by changing the SDK location path to "C:\PROGRA~2\Android\android-sdk".
Otherwise, if you cannot easily set the SDK location path in whatever IDE you use, you can solve it by creating a "legal" symbolic link to your actual SDK location. In Windows, you can use the command:
MKLINK /J C:\Android "C:\Program Files (x86)\Android\android-sdk\"And then you can just use the symbolic link location to refer to the actual SDK location.
Alternatively, I believe installing the SDK to a location with no spaces (e.g. "C:\android-sdk") would probably work as well.
