Overview (Java Platform SE 7 ) Launcher Icons. An icon is a graphic that takes up a small portion of screen real estate and provides a quick, intuitive representation of an action, a status, or an app.
When you design icons for your app, it's important to keep in mind that your app may be installed on a variety of devices that offer a range of pixel densities, as mentioned in Devices and Displays. But you can make your icons look great on all devices by providing each icon in multiple sizes. When your app runs, Android checks the characteristics of the device screen and loads the appropriate density-specific assets for your app. Because you will deliver each icon in multiple sizes to support different densities, the design guidelines below refer to the icon dimensions in dp units, which are based on the pixel dimensions of a medium-density (MDPI) screen. Launcher. Design. Canvas and Drawables. The Android framework APIs provides a set of 2D-drawing APIs that allow you to render your own custom graphics onto a canvas or to modify existing Views to customize their look and feel.
When drawing 2D graphics, you'll typically do so in one of two ways: Option "a," drawing to a View, is your best choice when you want to draw simple graphics that do not need to change dynamically and are not part of a performance-intensive game. For example, you should draw your graphics into a View when you want to display a static graphic or predefined animation, within an otherwise static application.
