I'm looking at doing development using the libgdx Game Development Framework for Android. It's pretty slick in that you can run things on your desktop before having to worry about deploying them to the target Android device. That, of course, is just the tip of the iceberg... it provides a whole bunch of stuff you need for doing audio, graphics, etc.
I'm running through the initial tutorials and am up to the projection-viewport-camera tutorial, tweaking things as I try things out. I'm thinking it would be a good exercise to port my Slide Rule to utilize libgdx.
Here are a couple of screenshots of my bouncing sprite.
