We touched nearly every +pixel of the system as we expanded the new design approaches introduced in Honeycomb tablets to all +types of mobile devices. Starting with the most basic elements, we introduced a new font, Roboto, +designed for high-resolution displays. Other big changes include framework-level action bars on +phones and support for new phones without physical buttons.</p> +<p>We focused the design work with three overarching goals for our core apps and the system at large. +As you design apps to work with Android, consider these goals:</p> + +<div class="vspace size-1"> </div> + +<div class="layout-content-row"> + <div class="layout-content-col span-4"> + +<h4>Enchant me</h4> +<p>Beauty is more than skin deep. Android apps are sleek and aesthetically pleasing on multiple levels. +Transitions are fast and clear; layout and typography are crisp and meaningful. App icons are works +of art in their own right. Just like a well-made tool, your app should strive to combine beauty, +simplicity and purpose to create a magical experience that is effortless and powerful.</p> + + </div> + <div class="layout-content-col span-5"> + +<h4>Simplify my life</h4> +<p>Android apps make life easier and are easy to understand. When people use your app for the first +time, they should intuitively grasp the most important features. The design work doesn't stop at the +first use, though. Android apps remove ongoing chores like file management and syncing. Simple tasks +never require complex procedures, and complex tasks are tailored to the human hand and mind. People +of all ages and cultures feel firmly in control, and are never overwhelmed by too many choices or +irrelevant flash.</p> + + </div> + <div class="layout-content-col span-4"> + +<h4>Make me amazing</h4> +<p>It's not enough to make an app that is easy to use. Android apps empower people to try new things +and to use apps in inventive new ways. Android lets people combine applications into new workflows +through multitasking, notifications, and sharing across apps. At the same time, your app should feel +personal, giving people access to superb technology with clarity and grace.</p> + + </div> +</div> diff --git a/docs/html/design/get-started/principles.jd b/docs/html/design/get-started/principles.jd new file mode 100644 index 0000000..0b7147b --- /dev/null +++ b/docs/html/design/get-started/principles.jd @@ -0,0 +1,300 @@ +page.title=Design Principles +@jd:body + +<p>These design principles were developed by and for the Android User Experience Team to keep users' +best interests in mind.
