Designer’s Guide to Supporting Multiple Android Device Screens
Unlike iPhones, Android devices do not have the same company developing both the software and hardware. This leads to different combinations of screen sizes, resolutions and DPIs and creates quite a challenge when designing and developing for these devices. While the iPhone 3G/S and iPhone 4 have different resolutions and DPI, they share the same screen size and the resolutions follow the same aspect ratio. Therefore, an image can be created to fit the iPhone 4’s specifications and be nicely down-scaled to the iPhone 3G/S. Credit to Steve Jobs for planning ahead and designing his phone with developers in mind. For some reason, manufactures using the Android OS on their phones did not give us the same luxury. We can spend all day comparing “Apples to Androids”, but instead let’s jump right into what we’re dealing with here. Popular Android Devices I thought it best to share a list of the most popular Android devices out in the market today and a few of their specifications.
Design - Devices and Displays
Android powers millions of phones, tablets, and other devices in a wide variety of screen sizes and form factors. By taking advantage of Android's flexible layout system, you can create apps that gracefully scale from large tablets to smaller phones. Be flexible Stretch and compress your layouts to accommodate various heights and widths. Optimize layouts On larger devices, take advantage of extra screen real estate. Assets for all Provide resources for different screen densities (DPI) to ensure that your app looks great on any device. Strategies So where do you begin when designing for multiple screens? For details about designing layouts for larger screens, see the Multi-pane Layouts guide.

Using the Emulator
The Android SDK includes a virtual mobile device emulator that runs on your computer. The emulator lets you prototype, develop and test Android applications without using a physical device. The Android emulator mimics all of the hardware and software features of a typical mobile device, except that it cannot place actual phone calls. It provides a variety of navigation and control keys, which you can "press" using your mouse or keyboard to generate events for your application. To let you model and test your application more easily, the emulator utilizes Android Virtual Device (AVD) configurations. The emulator also includes a variety of debug capabilities, such as a console from which you can log kernel output, simulate application interrupts (such as arriving SMS messages or phone calls), and simulate latency effects and dropouts on the data network. Overview The Android emulator is an application that provides a virtual mobile device on which you can run your Android applications.

CSS3 Properties
The W3C is currently working on CSS3 (Cascading Style Sheets, Version 3). The finished work will result in a number of CSS3 specifications, each one concerning a specific area of CSS. Although many of the specifications are currently a work in progress, many of the new properties have been adopted by the major browsers manufacturers in the form of their own proprietary properties (i.e. with their manufacturer's extension such as -webkit-, -moz-, etc). Below are a list of CSS3 properties. Following CSS3 Development If you're interested to see what happening with the development of the CSS3 specifications, check out the CSS3 current work.
