Microinteractions are small interface reactions to any particular action taken by the user in the app. Image Source:- What are Microinteractions? This way microinteractions in any app design help users visualize how the app’s UI interactions work. For example, On/Off sliders don’t really move like physical switches, but with animations, they appear to move. These not only dictate the visual appeal of an app but also lend the element of illusion in mobile UI interactions. Users may take these small actions for granted, but microinteractions in mobile UI design are what make any app usable and intuitive. Similar to these are the Transitions, which happen when switching screens but can also be used to create animations that move images around, altering their positions and properties.Microinteractions are the most subtle yet crucial part of all UI interactions in app design. Android has pre-defined effects with particular names (flip, zoom), it could be useful to know this vocabulary.įinally, layout changes are animations that happen when you reorder things around to better convey information or hint the user towards actions. E.g.: all buttons should have a ripple effect starting where the pointer clicks. This type may or may not involve image resources, and are usually applied to components of pre-defined types. One can also animate on the paths of the vector images, even morph between several of these, as long as the paths are compatible for morphing, which according to the documentation they must have the same number of commands and the same number of parameters for each command.this takes more understanding of the intrinsics of the vector file definitions, if you can see the image by reading the SVG code, go for it!Īnother major group comprises the animation (by acting on properties like color, position, size, etx) of the application UI elements. If the image is simple Vector Graphics would simplify the job for both the coder and the designer, regular SVGs are supported. Probably the same amount of different sprites you used for the video, never as many as 24/s! Keep in mind that to support different screen sizes and densities, different size/densities will have to be provided for each series. Here a common filetype would be PNG images, one for each step of the animation. PROTOPIE LOADING ANIMATION SERIESThis type of animation usually happens inside a pre-defined area on the screen and is achieved by loading a series of images, one after the other. PROTOPIE LOADING ANIMATION ANDROIDThe most common animations in android are:ĭrawable animations. Knowing the file types or formats the developer can or wants to use involves communication and you can expect them not to be always the same.Īlways provide a video of the animation, unless it can be described with a single word. Let's understand by resources anything that's not actual code: bitmap images, audio files, and even text. I dare to say this should never be conditioned by the nature or limitations of the provided resources. What type of files, prototypes designers should provide for the developer considering different cases?Īndroid animation API is really diverse, meaning there are lots of ways a developer may choose to deliver an animation. What are other technologies developers use to create animations? Designers try different ways to show the idea of animation but in this case all the work is left for a developer.ĭon't know when developers use this type and if designers can provide it using export from some design tools. PROTOPIE LOADING ANIMATION CODESince design tools don't generate production-ready code designers export video recording from tools like Principle, generate clickable prototypes in ProtoPie or other tools. UI elements that require complex interaction are usually build with code, like BubblePicker since it has changeable content in those bubbles and different conditions how it can be interacted with. Developer just gets the file and uses it as is, no more additional efforts for him. For a designer it's easy to provide JSON file since it can be generated with Bodymovin plugin in AfterEffects. I know Lottie works best for animating micro interactions and creating animated illustration, like those on onboarding pages. I'm a designer and interested in different ways I can handoff animation to Android developers and the best ways to do that depending on a particular case. ![]()
