In a document titled “Application Design Goals,” Google provides objectives with three areas of focus: performance, responsiveness, and seamlessness. It also provides a short list of recommendations: don’t drop data, don’t interrupt the user, design your UI to work with multiple screen resolutions, assume the network is slow, don’t assume the touchscreen or keyboard exists (i.e., write logic to detect them), and conserve the device’s battery. Even though this document is targeted at Android development, it is insightful to ActionScript developers as well. Read it at http://developer.android.com/ guide/practices/design/index.html.
