O.K. I resolved this.  The problem was related to the fact that
Eclipse couldn't properly handle the gen directory that it created.
This error is generated:

[2009-04-30 14:14:15 - MyApp] /MyApp/gen already exists but is not a
source folder. Convert to a source folder or rename it.

So, here's how I resolved this problem:

1. Make sure Android 1.1 platform is selected for the project.
2. Delete the gen directory - let Eclipse update .classpath (if it
asks).
3. Clean the project - Eclipse will regenerate the gen directory
4. Add the directory gen to the Java source classpath if R.java cannot
be resolved.
5. Clean the project again.
6. if you still have a problem with the above error showing up, delete
the gen directory again and let Eclipse regenerate it.

This should clear up the error.  Perhaps a change to the Eclipse
plugin or the Eclipse API needs to be made - I don't know.

But, at least my projects are building now.
