I've obviously been spoiled by Visual Studio, because although I'm just learning Android and the Eclipse environment, debugging apps in Eclipse is becoming a serious detriment to further development.
For example, Eclipse will compile this divide by zero just fine:
public class Lesson2Main extends Activity
{
/** Called when the acti...

Having them hunt for the app or using the notification menu is not a workable option (too m...
