Right now there's no good way to define settings for application name or icon.

Having no icon associated with the APK excludes the app from being able to be posted on the
Android Market (the interface for uploading the APK to the Market will notify you and stop the
uploading from happening).

The Android Market is an exciting way for Processing students and developers to immediately
share their sketches with the world, so this issue is higher priority than it appears.

Right, just like the 'applet' folder is destroyed on every build. There
isn't a good way around this, because people will make a mess of the files
(just like with the applet folder). It's possible that we can do some
overrides (the way you can with applet.html), but I'll hold off until
there's a real compelling reason to do so.

The application name is the sketch name, and is written into the manifest
file. Do you mean that you can't set the package name?

Icon would be another issue, will need to look into that.
