Are you really using "package.name" in the monkey
command line rather than your actual package name?
Did you ensure the APK was installed on the emulator before running monkey?
Otherwise, is there any output in the logcat.txt
which indicates what's going wrong?
Also, I'm not sure why you linked to a really old version of the Android Emulator Plugin wiki page, but since then there's a Jenkins build step that will run monkey for you, without you having to manually write it into a batch script step.
