Apply transformations, such as translation, scaling, or custom transformations.The Paint object holds the style and color information about how to draw geometries (such as line, rectangle, oval, and paths), or for example, the typeface of text. Draw shapes, such as rectangles, arcs, and paths styled as defined in a Paint object.The types of operations you can perform on a canvas include: In this codelab, you learn how to create and draw on a canvas that is displayed in a View. This is useful when your app needs to regularly redraw itself, because what the user sees changes over time. The Canvas is a 2D drawing surface that provides methods for drawing. In addition to using drawables, you can create 2D drawings using the drawing methods of the Canvas class. In Android, you have several techniques available for implementing custom 2D graphics and animations in views. We recommend that you do all the codelabs in order, because they progress through tasks step-by-step. This codelab is part of a series that guides you through building custom views, drawing on a canvas, clipping canvas objects, and using shaders for cool effects. All the course codelabs are listed on the Advanced Android in Kotlin codelabs landing page. You'll get the most value out of this course if you work through the codelabs in sequence, but it is not mandatory. Instead of keeping those settings in your build scripts, let’s simply delete them (you can always restore them from your VCS history if needed).This codelab is part of the Advanced Android in Kotlin course. If you used the UI before switching to Kotlin DSL, there is a significant chance your build scripts contain a fair number of disabled settings, like obsolete build steps, triggers, and requirements. Remove disabled build steps, triggers & requirements In this article, we’ll discuss the next steps you can take. Your builds run successfully, but what next? What small refactorings can you apply to your Kotlin DSL code to help keep it clean and tidy?

Imagine you have just switched your TeamCity project over to Kotlin DSL.
