Re-using graphics designed for different operating systems, especially desktop-based, is not a good idea.

Re-using graphics made for different systems, especially desktop-based, is not a good idea. Foreign graphics will look weird at best, or will make your Android apps hardly recognizable at worst. Body: There exist strict guidelines published 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 should be supplied in two distinct states: unselected and selected. It is required that tab icons are designed as simple, flat shapes as opposed to graphics 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 images, those devices can have different screen sizes, screen resolutions, pixel density and dimensions. To accommodate the wide range of displays, Android developers must provide 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 providing 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 used in the "options" menu, and are shown to the user when they press the Menu button. Similar to tab icons, menu icons are specified as flat, grayscale images. Just as tab icons, developers should not use 3D or isometric projections. Screen sizes for menu icons are defined in a slightly more complex way as opposed to to tab icons. Instead of two resolutions defined for tab icons (inner shape and boundary box), the inner shape of menu icons can be smaller or bigger depending on their shape. If a menu icon is square-shaped, its resolution should be smaller than for icons with different shapes. The reason for specifying two different size limits is to establish a consistent visual weight across the two icon types. The outer dimensions for ldpi, mdpi and hdpi 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 pixels. Similarly, mdpi icons should fit 30x30 and 32x32 pixel boxes, while high-definition images should fit into 44x44 and 48x48 pixel rectangles respectively. Instead of drawing your own icons matching these guidelines, Android developers have an option of ordering stock graphics from professional designers. For example, Android Tab Icons by Aha-Soft offer 112 unique tab icons in selected and unselected states and all three standard resolutions. If an additional size is needed, developers can produce icons at any size by accessing scalable vector sources.
