Of course, Oracle's action threatens what we know as Sun's Java.

Indeed, it kills Java ME stone dead. But it was dead a couple of years ago. So no loss there.

However, I'm not clear how this affects Android, since Android is not Java.

When I code Android I 'feel' like I'm coding Java, because the syntax is the same. But I'm not running Java. I know that, and I feel that.

So, if Oracle want to attack Java, or protect its patents, take your pick, I say: knock yourself out. Here in Android world, it's no concern of mine as I'm not using Java.

Attacking Java isn't an attack on Android development. Although that appears to be what Oracle thinks it is doing.
