Re-using images made for other systems, especially desktop-based, is not a good idea. Foreign icons will look out of place at best, or will render your Android apps appear hardly recognizable at worst.Producing Tab and Menu Icons for Android Apps Description: When designing Android apps or designing graphics for Android apps, one must conform to srict guidelines. Using images designed for other systems, especially desktop-based, is not a good idea. Foreign graphics will look weird at best, or will render your Android apps hardly recognizable at worst. Body: There are precise guidelines available for designing standard-compliant Android icons. Different design guidelines are available for tab icons and menu graphics. ![]() Tab icons are drawn in individual tabs in tabbed interface. Tab icons must be provided in two different states: unselected and selected. It is required that tab icons are created as simple, flat shapes as opposed to images drawn in 3D or isometric projection. Android OS and Android apps are used on a wide range of hardware platforms employing a wide range of hardware. In reference to icon graphics, those platforms can have different screen sizes, display resolutions, pixel dimensions and density. To accommodate the wide range of screens, Android developers should supply all tab icons used in their apps in at least three resolutions to be displayed on low, medium, and high density screens. Resolution-wise, the outer boundaries for the three resolutions are defined as 24x24, 32x32, and 48x48 pixels. The size of the shape itself should not exceed 22x22, 28x28, and 42x42 pixels respectively. By supplying all three standard resolutions, developers can ensure that their apps will display properly on a wide range of platforms running the Android OS. Menu icons are displayed in the "options" menu, and are shown to the user when they press the Menu button. Similar to tab icons, menu icons should be flat, grayscale images. Like tab icons, developers should not use 3D or isometric projections. Pixel sizes for menu icons are defined in a slightly more comprehensive way as opposed to to tab icons. Instead of just two sizes defined for tab graphics (inner shape and boundary box), the inner shape of menu icons can be smaller or larger depending on whether they are square-shaped or not. If a menu icon is square-shaped, its dimensions should be smaller than for icons shaped otherwise. The reason for specifying two different size limits is to establish a consistent visual size across the two icon types. The outer dimensions for low, medium, and high resolution icons are described as 36x36, 48x48, and 72x72 pixels respectively. Inner shapes for square, low-definition icons should be 22x22 pixels, while non-square icons should fit into a boundary box sized 24x24 dots. Similarly, medium-definition icons should fit 30x30 and 32x32 pixel boundaries, while high-definition images should fit into 44x44 and 48x48 pixel boundaries respectively. Instead of drawing your own images conforming to these guidelines, Android developers have an option of obtaining stock images from professional designers. As an example, Android Tab Icons by Aha-Soft offer 112 unique tab images in both states and all three standard sizes. Should additional resolutions be required, developers can render images at any resolution by opening scalable vector sources.
