I'm totally cool with this.

So, this feature existed because people want Eclipse to auto-build?
I've turned off that "feature" in Eclipse years ago, and I've never
been happier.  Sure, it means that I have to actually decide when I
want to build in Eclipse to see my errors, but I actually LIKE that,
because it's useless to see that I broke things when a change is not
even halfway written.

So, pretty much any modern Android project.

1. Can't you can do incremental builds in bin and gen by unchecking
"Build Automatically", or by not using Eclipse and only using Ant?
2. We may want to move to Gradle
3. Ant vs Gradle is an either/or thing, and I'm not looking forward to
the move, but I feel like it's closer than we think.
