Using images made for other operating systems, especially desktop-based, is not a good idea. Foreign icons will look out of place at best, or will make your Android apps appear hardly recognizable at worst.Designing Standard Tab and Menu Icons for Android Apps Description: When designing Android apps or drawing graphics for Android apps, it is essential to follow certain guidelines. Using graphics designed for other systems, especially desktop-based, is not a good idea. Foreign images will look out of place at best, or will make your Android apps appear hardly recognizable at worst. Body: There exist precise guidelines published in reference to Android icons. Different design guidelines are available for tab icons and menu images. ![]() Tab icons are drawn in individual tabs in tabbed UI. Tab icons should be supplied in two different states: selected and unselected. It is recommended that tab icons are designed as simple, flat shapes as opposed to images shown in 3D or isometric projection. Android OS and Android apps are used on a variety of hardware platforms using a wide range of hardware. In reference to icon graphics, those devices can have different screen sizes, screen resolutions, pixel density and dimensions. To accommodate the wide range of screens, Android developers should provide all tab icons used in their apps in at least three resolutions to be displayed on low, medium, and high density screens. Pixel-wise, the outer boundaries for the three resolutions are defined as 24x24, 32x32, and 48x48 pixels. Inner dimensions should not exceed 22x22, 28x28, and 42x42 pixels respectively. By supplying all three standard sizes, developers can ensure that their apps will display properly on a wide range of devices running the Android OS. Menu icons are drawn in the "options" menu, and are shown to users when they press the Menu button. Similar to tab icons, menu icons are specified as flat, greyscale images. Just as tab icons, developers cannot use 3D or isometric projections. Screen sizes for menu icons are defined in a slightly more comprehensive way as opposed to to tab icons. Instead of two sizes described for tab graphics (inner shape and boundary box), the inner shape of menu icons can be smaller or bigger depending on whether they are square-shaped or not. If a menu icon is square-shaped, its dimensions should be smaller than for icons with different shapes. The reason for specifying two different size limits is to establish a consistent visual size across the two icon types. The outer dimensions for ldpi, mdpi and hdpi icons are defined 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, mdpi icons should fit 30x30 and 32x32 pixel boundaries, while high-definition images should fit into 44x44 and 48x48 pixel rectangles respectively. Instead of designing your own images matching these guidelines, Android developers have an option of getting stock graphics from professional designers. For example, Android Tab Icons by Aha-Soft include 112 unique tab icons in both states and all standard sizes. Should additional resolutions be required, developers can render images at any resolution by opening scalable vector sources.
