Адаптивные значки

В Android 8.0 Oreo появилась поддержка адаптивных значков.

Для работы с адаптивными значками следует использовать API 26 и выше. Адаптивные значки состоят из двух слоёв: фон и основная часть.

В манифесте по-прежнему остаётся старая запись о значке.

Далее следует создать файл res/mipmap-anydpi-v26/ic_launcher.xml. Android Studio 3.0 генерирует подобный файл, можете изучать его.

Слои содержат векторные изображения VectorDrawable. К слову сказать, в качестве фона можно использовать просто цвет.

Для передней части значка можно использовать PNG-файл (используйте ресурсы mipmap).

Для совместимости с Android 7 вы должны также создать ещё один файл ic_launcher_round.xml с таким же содержанием.

Если изучить ресурс для фона, то можно заметить, что для значка используются размеры 108dp*108dp. Основной слой значка имеет те же размеры, но нужно учитывать одно обстоятельство — фоновый слой работает как маска, накладываемая на передний значок. Поэтому вы должны проследить, чтобы маска случайно не закрыла важные детали значка.

Гарантировано будет виден центр значка 66dp, а 77dp применимо к общему размеру значка.

Адаптивные значки можно применить к App Shortcut.

На эмуляторе следует выбрать устройство Pixel и включить у него режим разработчика. Далее в настройках домашнего экрана появится пункт Change icons shape.

Understanding Android Adaptive Icons

Android O introduces a new format for app icons called adaptive icons. To better understand the motivation and potential of this feature it’s useful to take a look at what it’s replacing.

While Android’s icon guidelines have evolved over time, they have always promoted using unique shapes. I was a huge fan of this! I held that it really helped users to locate the app they wanted to launch. If you want to get nostalgic you can listen to Roman Nurik and I talk about this to 6 whole minutes in an old video we made.

Here’s the ‘traditional’ icon (created by Roman) from Plaid, an app I work on. I believed that the distinct shape helped it to stand out, making it easier to find:

But it’s not all sunshine and rainbows in distinct-shape-icon-land. The flipside of this near-complete creative freedom is lack of consistency. When each individual app is responsible for shape, size and drop-shadow (which is baked into the icon) then the inevitable consequence is that they vary widely. Here’s an example of icons just from Google showing how they at one time varied:

Now admittedly the above image is from 2012 and things have improved a lot in the meantime; especially with the extra guidance in the material guidelines. Nonetheless, I’ve come to believe that the current system places too much responsibility on app developers; giving us too much scope to detract from the overall experience..

When we’re working on an app, we can become laser-focused on it. We rightly spend huge amounts of time pouring over the details that make it unique. We think about it in isolation. But that’s not how users see it; no app is an island and we need to recognize that it exists alongside many other apps on a device. As such it needs to get along. This is true for your entire app but it’s all the more important with elements like app icons which appear side by side. With this framing we can see how instead of our idealized situation, the reality often ends up being more like this:

In response to this problem, a whole cottage industry has sprung up: custom launchers offering icon packs to replace app’s icons or normalize their size. Devices also started shipping with launchers adding backgrounds to app icons to enforce consistency & brand their platform.

Indeed Google’s launcher will start placing icons of apps which target Android-O but do not supply an adaptive icon onto a background (scaling down their non-adaptive icon).

While normalizing icon shapes or sizes is understandable, altering an icon without input from the app developer can’t lead to the best outcome.

Android 7.1 introduced roundIcon as an attempt to bring some consistency here but this was pretty restrictive to OEMs looking to differentiate their devices (i.e. only supporting circular icons) and lacked any kind of validation (developers could supply any shaped icon and pinky-swear that it was round!).

I’d characterize the situation as lacking a well defined contract between the app icons and launchers which will display them. Balancing the complete freedom of icon design against a desire for consistent display currently places responsibilities in the wrong camps. Launchers try to resize icons but don’t understand the content, like which elements are critical and shouldn’t be touched. App icons need to keep up with any guideline changes to ensure they bake in correct sizing/padding or shadow information. I see adaptive icons as making this contract clearer; becoming more explicit about what an app must supply and how a launcher will consume and display it.

For icon makers, it’s easy to see this as losing some freedom. I think this is actually more of a shift rather than a reduction. Adaptive icons introduce new and interesting constraints that open up new creative possibilities. Join me in part 2: designing adaptive icons to explore these.

VectorDrawable Adaptive Icons

So the Android O APIs are final — API 26 is here! That means you can start compiling with API 26 right now (and you should really always compile with the latest SDK) as well as work towards targeting API 26.

One of the first things you should consider working on is providing an adaptive icon — an icon made of a separate background and foreground layer. This new format provides a consistent shape across all icons on a device and will also allow launchers to add visual effects by animating the background and foreground separately. This is really how you make a good first impression for users with Android O devices.

With the system handling the outer edge shape and its shadow, adaptive icons give you a chance to re-evaluate how you build your app icon. If you’re able to build your app icon as an SVG/vector image, consider avoiding bloating your app with more PNGs for the background and foreground and take advantage of VectorDrawables for your adaptive icon.

Note: there are valid cases where PNGs are the correct choice for your app. Talk to your designer before trying to force everything into vector drawables.

I’ll walk you through what it took to convert Muzei’s current icon into an adaptive icon.

Note: you do not need to target API 26 to provide an adaptive icon — only compile against it. Users will benefit from your work even as you work through other behavior changes.

The basics of adaptive icons

By placing it in the mipmap-anydpi-v26 folder, the resource system will use it in preference over any files in the other dpi folders (exactly what you want, since this file is replacing all of them) and that it should only be used in API 26+ devices.

You’ll notice that the drawables are in the drawable directory. This is because I’m using vector drawables. If you are using PNGs, this should most definitely be in mipmap . Another option is use a color resource for your background:

Round icons

For those of you with an android:roundIcon , you must keep that attribute to continue to support API 25 devices. Devices with round masks will use your custom roundIcon if available, but it is strongly suggested to use a single adaptive icon for those devices as well (this ensures you get the standard shadow, support for visual effects, etc).

I find this easiest by creating an alias resource. You’d keep your ic_launcher_round images in the res/mipmap directories for API 25 devices, but add a file in your values-anydpi-v26 folder:

Building a VectorDrawable Background

The background is a great place to start. Being a full bleed 108 x 108 dp image, there’s not much special about this one:

Just keep in mind that due to the masking of the image, users will usually only see the middle 72 x 72 dp.

Building a VectorDrawable Foreground

The foreground image, on the other hand, offers a unique challenge.

First, you have to handle creating the foreground shape itself. It is still on the same 108 x 108 dp artboard, but the ‘safe zone’ of what you know will be shown is only a middle circle of radius 33 dp — don’t put anything critical outside of that part!

Where I initially got stuck was when it comes to the traditional 45º material cast shadow that the foreground also needs to include. Normally, this would be where you’d have to break out the PNGs to get that perfect gradient. But gradient support was added to VectorDrawables back to API 24!

Getting gradients working, however, required a bit of research. The VectorDrawable docs point out the ability to use a GradientColor , but where to find a good example? On StackOverflow of course.

Now, Roman Nurik, the maker of the original Muzei icon, had made a fantastic SVG version of the launcher icon including the shadow as a
element in the SVG. I won’t pretend that I know how he came up with the correct values — talk to your local designers or read the material design guidelines for product icons a couple hundred times.

But what it became was a res/color/ic_launcher_shadow.xml file that looks like this:

You’ll note all of the attributes from the GradientColor documentation available to customize this to be just right.

Note: As of Android Studio 3.0 Canary 3, Android Studio flags gradient as an error (‘Element gradient must be declared’). It still works.

Now, we can refer to our gradient color the same way you’d refer to a color: with @color/ic_launcher_shadow in the VectorDrawable . In Muzei’s case, this means that the foreground background consists of two paths: the shadow and then the shape below it:

Note: this is also how you’d add a finish layer to your icon — a separate gradient above your shape as explained in the material design guidelines.

All the benefits, none of the APK bloat

By taking advantage of API 24’s addition of gradients to VectorDrawables, we can build well designed VectorDrawable adaptive icons that have the correct material shadows on foreground elements without resorting to adding even more PNGs into the app.

If you want to see it in action, join Muzei’s open beta, then download Muzei on an Android O Dev Preview 3 device and check out the commit that added the adaptive icon. (Although unless you have the superhuman ability to visualize VectorDrawables like Nick Butcher, you might find the full commit doesn’t add much over the code we already covered.)

47 Best Icon packs: Round, Square, Minimal, Transparent, Light, Dark, White, and more types

You already know how awesome Android is at customizing your device. Be it changing the wallpaper, ringtone, theme, buttons, LED notification light or icons, everything is possible on Android.

Talking about icons, in case you didn’t know, you can change the icons on your device with the icon packs. Icon packs are cool and give a new look to your device. Icon packs are apps, like any other app on the Google Play Store but instead of adding any new functionality, they replace the default boring icons on your device with the customized icons based on your liking.

However, you cannot use the icon packs directly on default launchers as most of them do not support the icon packs, you have to install a 3rd party launcher first. Here is our detailed guide on how to use and apply icon packs using 3rd party launchers.

Anyway, back to the awesomeness of icon packs. Google Play store is loaded with lavish icon packs and it becomes quite difficult to choose between them. So, we have made it easier for you by hand-picking the best icon packs available on the Play store in different categories.
