Installing apk on emulator in mac

I have followed following tut to install messaging-simulator.apk on my Nexus 7 emulator of adt sdk...

http://www.orhancanceylan.com/installing-and-testing-apk-files-to-the-android-emulator-on-mac/

But, after the device (virtual) is launched (which is annoyingly slow), no further action could be performed from terminal as it gets stuck or no progress is shown. (Basically, I am stuck after ./android command. Nothing can be entered in terminal after that. How do i resolve this?

This is how it looks now at the end!, emulator not up!

Solution

Thanks a ton to @Uriel Frankel. Yet, all those tips and tricks given by him did not work out for me due to low memory in my macbook.

So I have used Genymotion emulator(http://techapple.net/2014/05/3-best-android-emulators-for-mac-os-macbook-run-and-install-android-app-on-your-mac-os-x-macbook-airpro/) instead of default android emulator and successfully launched the app by installing it.

You can all try above solution first and if it did not work out, use Genymotion, it's cool :)
