Design principles
These design principles were developed by and for the Android User Experience Team to keep users' best interests in mind. Consider them as you apply your own creativity and design thinking. Deviate with purpose.
Enchant Me
Delight me in
surprising ways
A beautiful surface, a carefully-placed animation, or a
well-timed sound effect is a joy to experience. Subtle effects contribute to a
feeling of effortlessness and a sense that a powerful force is at hand.
Real objects are
more fun than buttons and menus
Allow people to directly touch and manipulate objects in
your app. It reduces the cognitive effort needed to perform a task while making
it more emotionally satisfying.
Let me make it mine
People love to add personal touches because it helps them
feel at home and in control. Provide sensible, beautiful defaults, but also
consider fun, optional customizations that don't hinder primary tasks.
Get to know me
Learn peoples'
preferences over time. Rather than asking them to make the same choices over
and over, place previous choices within easy reach.
Simplify My Life
Keep it brief
Use short phrases with simple words. People are likely to
skip sentences if they're long.
Pictures are faster
than words
Consider using pictures to explain ideas. They get people's
attention and can be much more efficient than words.
Decide for me but
let me have the final say
Take your best guess and act rather than asking first. Too
many choices and decisions make people unhappy. Just in case you get it wrong,
allow for 'undo'.
Only show what I
need when I need it
People get overwhelmed when they see too much at once. Break
tasks and information into small, digestible chunks. Hide options that aren't
essential at the moment, and teach people as they go.
I should always
know where I am
Give people confidence that they know their way around. Make
places in your app look distinct and use transitions to show relationships
among screens. Provide feedback on tasks in progress.
Never lose my stuff
Save what people took time to create and let them access it
from anywhere. Remember settings, personal touches, and creations across
phones, tablets, and computers. It makes upgrading the easiest thing in the
world.
If it looks the
same, it should act the same
Help people discern functional differences by making them
visually distinct rather than subtle. Avoid modes, which are places that look
similar but act differently on the same input.
Only interrupt me
if it's important
Like a good personal assistant, shield people from
unimportant minutiae. People want to stay focused, and unless it's critical and
time-sensitive, an interruption can be taxing and frustrating.
Make Me Amazing
Give me tricks that
work everywhere
People feel great when they figure things out for
themselves. Make your app easier to learn by leveraging visual patterns and
muscle memory from other Android apps. For example, the swipe gesture may be a
good navigational shortcut.
It's not my fault
Be gentle in how you prompt people to make corrections. They
want to feel smart when they use your app. If something goes wrong, give clear
recovery instructions but spare them the technical details. If you can fix it
behind the scenes, even better.
Sprinkle
encouragement
Break complex tasks into smaller steps that can be easily
accomplished. Give feedback on actions, even if it's just a subtle glow.
Do the heavy
lifting for me
Make novices feel like experts by enabling them to do things
they never thought they could. For example, shortcuts that combine multiple
photo effects can make amateur photographs look amazing in only a few steps.
Make important
things fast
Not all actions are equal. Decide what's most important in
your app and make it easy to find and fast to use, like the shutter button in a
camera, or the pause button in a music player.
