How do you load two apps onto the android emulator?

I am using Eclipse to develop a couple of apps for Android phones. I want to experiment with one app starting the other via startActivity(). What is unclea开发者_StackOverflow社区r to me, is how to I get both apps loaded onto the emulator. How do I get both apps onto the emulator so, I can test their ability to start each other?

First start one from Eclipse (it will be installed). Then start the next. Now both are in your emulator.
