You can imagine how limiting this is compared to the vector format which describes the images as a series of points and paths composing shapes on an arbitrary grid size, which can also be colored dynamically. These are grids of pixels that are a fixed size only containing color information. PNG) are what you probably have the most experience with in the past. Well, to understand more you can compare with the older format, raster images. Why do you need this type of image format though if Android supports the ability to serve different resources using the density resource buckets? You can think of this process as drawing an image on paper using a pen or pencil. While the API on Android is not a one-to-one match with the SVG format provided by the web, it offers the ability to draw individual paths, groups of paths, and create clipping masks to compose complex graphical assets for your applications. The SVG format is an open standard image format defined by the World Wide Web Consortium (W3C) for creating scalable, interactive and animatable images through XML. They are defined in XML using resource files and can be dynamically altered at runtime. VectorDrawables are the SVG equivalent on Android. Try saving one.īy clicking History in the toolbar, you can view your creation. The first screen you’ll see is one where you can place baby-faced emojis on a background. If you need to brush up on any of these things, you can check out Beginning Android Development with Kotlin, Part One: Installing Android Studio or Kotlin For Android: An Introduction.īuild and run the app. You should also be familiar with the Kotlin programming language. Note: This tutorial assumes that you are generally familiar with building applications in Android Studio and working with assets to add resources to your project. Then, import the project into Android Studio to get started. Getting Startedĭownload the project materials using the Download Materials button at the top or bottom of this article. Finally, you will wrap up the tutorial by learning how to animate a vector drawable to create a cool loading animation on the splash screen of the app. In addition, you will learn how to apply them to widgets and about the support Android provides for SVGs on lower API levels. You will also learn by using the related APIs in Android. You will learn about this format through the standard SVG pathspec commands available which will help you to understand the theory behind drawing them. Vector graphics are an extremely powerful image format that both reduce your apk’s size and provide a more dynamic visual appearance that scales across the various screen densities within the Android ecosystem. In this tutorial, you will work with scalable vector graphics (SVG) on Android to build an application that creates shareable images using baby-faced emojis that can be scaled and repositioned on a background image.
