Looking for any kind of recommendation, like books, articles, anything that aids me in getting started with game development in Android.

Android - Is my App Draining Battery
I'm developing a game for Android. It uses a surface view and uses the sort of standard 2D drawing APIs provided. When I first released the game, I was doing all sorts of daft things like re-drawing 9-patches on each frame and likewise with text. I have since optimised much of this by drawing to Bitmap objects and drawing them each frame, only re-drawing onto the Bitmap objects when required.
I've received complaints about battery drain before, and following my modifications I'd like to know (scientifically) if I've made any improvements. Unfortunately, I don't have any prior data to go by, so it would be most useful to compare the performance to some other game.
I've been running Traceview, and using the results of it mostly for the purposes of identifying CPU-time-consuming methods.
So -- what's the best way of determining my app's battery performance, and what's a good benchmark?
I know I can look at the %s of different apps through the settings, but this is again unscientific, as the figure I get from this also depends on what's happening in all of the other apps. I've looked through (most of) Google's documentation, and although the message is clear that you should be saving battery (and it gives the occasional tip as to how), there is little indication of how I can measure how well my app is performing. The last thing I want are more complaints of battery drain in the Android Market!

Android - Tutorials and libraries for OpenGL-ES games
What tutorials and libraries are available which can help beginners to develop 2D and 3D games on Android using OpenGL-ES? I'm looking for tutorials which can help me learn OpenGL-ES, and I'm looking for OpenGL-ES libraries which can make life easier for beginners in OpenGL-ES.
Since Android is still small, I guess it may be help-full to read iPhone OpenGL-ES tutorials as well, as I suppose the OpenGL-ES functionality is much the same.
I have found the following useful information which I would have liked to share:
Android tutorials:
Other Android OpenGL-ES information:
What else is out there?

Other Android OpenGL-ES information:
- Google IO lecture regarding games, not much OpenGLES
- The The Khronos Reference Manual is also relevant to have, but its not exactly the best place to start.
