Java: How do I start a standalone application from the current one when both are in the same package?

Java

This seems like it should be easy, so I must be missing something obvious: I have 4 standalone applications in the same package, us.glenedwards.myPackage,

myClass1 extends Application
myClass2 extends Application

etc...

I need each class to act as its own standalone application. Yet I want to be able to start the other 3 classes from the one I'm in by clicking a link. Android allows me to do this using Intents:

Intent intent = new Intent(this, EditData.class);
overridePendingTransition(R.layout.edit_data_scrollview, R.layout.state);
startActivity(intent);

I've tried starting myClass2 from myClass1 using

myClass2.launch("");

But I get an error, "Application launch must not be called more than once". The only way I can get it to work is if I remove both "extends application" and the start() method from myClass2, which means that myClass2 is no longer a standalone application.

How can I start myClass2, myClass3, or myClass4 from myClass1 with all 4 of them being standalone applications?
