Prototypes, sure, but people always mention it to say “You can write apps in Python on Android”. That’s simply not true.
SL4A is kinda like PhoneGap: you can use it, but you will not get a quality app out of it. That might be fine for your use case, but it’s definitely not on par to using the canonical platform.
Other quick notes: The last commit on the Scala for Android project is from two years ago and says “add 2.2 support”, the related blog post is from one year ago. Same deal with Android ObjC: last commit April 2010. I would never trust either of these for production development.
I’m sorry but languages other than Java and C++ for Android development are closer to vaporware than reality right now. The only good alternative is Mono http://xamarin.com/monoforandroid which is actually working and supported and not a forgotten weekend hack.

Please note: I’m perfectly fine with Java.
