The Latest news from the Android developers blog is the recent release of stencils for Android Design. According to Android designer Alex Faaborg, it was "by far the number one request we received.":
When we initially released Android Design, by far the number one request we received was for us to release stencils as well. The fine folks on the Android User Experience team are pleased today to release some official Android Design stencils for your mockup-creating pleasure.
With these stencils you can now drag and drop your way to beautifully designed Ice Cream Sandwich (Android 4.0) applications, with grace and ease. The stencils feature the rich typography, colors, interactive controls, and icons found throughout Ice Cream Sandwich, along with some phone and tablet outlines to frame your meticulously crafted creations.
Currently we have stencils available for those venerable interactive design powerhouses Adobe Fireworks, and Omni OmniGraffle and we may expand to other applications in the future. The source files for the various icons and controls are also available, created in Adobe Photoshop, and Adobe Illustrator.
