Re-using graphics made 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 exist strict guidelines available in reference to Android icons. Different design guidelines are published for tab icons and menu icons. ![]() Tab icons represent individual tabs in tabbed interface. Tab icons must be provided in two different states: selected and unselected. It is recommended that tab icons are designed as simple, flat shapes as opposed to graphics drawn in 3D or isometric projection. Android OS and Android apps can run on a multitude of hardware platforms using a wide range of hardware. In connection to icon graphics, those devices can have different screen sizes, display resolutions, pixel density and dimensions. To accommodate the variety of displays, Android developers should supply all tab icons used in their apps in at least three resolutions to be shown on low, medium, and high density screens. Pixel-wise, the outer boundaries for the three sizes 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 sizes, designers can ensure that their apps will be shown properly on a wide range of devices running the Android OS. Menu icons are drawn in the "options" menu, and are displayed 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 described in a slightly more comprehensive way compared to tab icons. Instead of two resolutions 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 resolution 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 defined as 36x36, 48x48, and 72x72 pixels respectively. Inner shapes for square, low-definition icons is 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 boxes, while high-definition images should fit into 44x44 and 48x48 pixel boundaries respectively. Instead of designing your own icons matching these guidelines, Android developers have an option of getting stock images from professional designers. For example, Android Tab Icons by Aha-Soft offer 112 unique tab icons in both states and all standard sizes. If an additional size is needed, developers can produce images at any resolution by accessing scalable vector sources.
