I can't provide any input from my keyboard or from the on-screen keyboard when using keytool to generate key pair (public and private keys) and a signing certificate.
This problem occurs only when executing this command not in any other commands.
I tried using running command from .bat file but still can't provide any input.

The only input i can provide is enter(button).
So should i go forward by again providing enter(button)?
Note: I am referring Oreilly Android Application Development 2009.pdf
