A poster on one of the other android posts mentioned you can just telnet into the android app if you've got the emulator running.
Its easy to do and the preferred way if you just want to script events. Just telnet into localhost 5554 and you can issue emulator commands.
user@dev:~$ telnet localhost 5554
Trying ::1...
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
